Stuttering:
Q:What is it ? Well if you enter the thirsty dog first time and you're screen is shaking as hell and you get 1 frame per X seconds instead of X fps (AKA the slideshow effect) that's the stuttering effect we're talking about =P
Q:Why does it happen and why does it still happen even though I have teh strongest bleeding edge new computer in the world ?
To generate the possibly insane goodlooking graphics the game uses objects called "shaders". Shaders are small programs that alter pixels or vertices. Consequently, there are two major types of shader - pixel shaders and vertex shaders. These tiny programs add effects to basic geometry - so a water-styled shader can be added to a flat blue texture to make it look reflective, or a glass-styled shader can be added to a polygon to make it appear transparent. These shaders are the key to what makes the graphics in games today look so much better than the graphics in games from let's say 5-8 years ago. These shaders are programmable, so games developers can make their own, allowing them to create a unique look and feel for their game and that is what Funcom has done. Now the problem is that some of these shaders in many area's in the game are not known yet known to your betaclient so when that happens the game uses the graphic card's onboard processing unit (the GPU) to compile (sort of calculate) the shader results and then displays them. The time of compilation is what gives the feeling of insane stuttering which is super annoying.
Q now we know the problem, how does Funcom handle it ?
Funcom thought of this when developing AOC. Their solution was and still is to simply have your computer hold the results of every compilation in memory -so that this stuttering would be a one-time thing as long- as you are standing in that 1 small space or area (let's say the area of thirsty dog inn). When you log off and exit AOC, the AOC client is supposed to write down those results from memory into a file on your harddisk so that all compilation results don't have to be done all over again next time. Upon a clean client exit (which never happens because AOC crashes all the time currently and therefore loses it's compiled shaders) it saves all these changes into a file in the general beta folder and that file is called "shader.cache.local"
As the result is calculated it's kept into memory as long as it's needed which means that if you leave the area to go and find new "previously unknown shaders" your current ones will be lost from memory and replaced by new ones which means you'll have the stuttering again. Also, after every crash you lost your compilations before your computer had the chance to write them down so you'll have the same stuttering upon next logon...
Q:So what's the magic trick then to get rid of the stuttering ?
Basically whenever your computer has compiled new shaders you want to immediately save those results to disk so your computer gets them from there next time instead of having to do it all over. That way you'll have no or almost no stuttering since it's much faster reading out the results than recompiling them. There's a button in the game that you can press to instantly save the current results of a shader compilation into the shader.cache.local file (you will actually see it grow in size when you do) and you want to do this RIGHT AFTER YOU FORCED/EXPERIENCED SOME STUTTERING because of new shaders being compiled.
Q:so where's that magic button ?
When you are in game, first open the debugging menu:
ctrl + ù for french keyboards
ctrl + for UK keyboards.
strg + ö for german keyboards.
Then press "dump shaders" because that is the magic button to save the results.
Q:What's the best way to test or use it ? You do it like this:
1. Upon feeling horrible graphics stuttering, stop running and start looking around 360°, move a bit back and forth and explore the very smalll area around your feet a bit until all stuttering stops and everything is fluent (this is when the computer has finished compiling the shaders of that area and has the results freshly in memory)
2. open the debug menu and press "dump shaders" to save the results to the file on your harddrive. You're safe now for next time you come across this small area
3. keep on repeating this everytime you experience stuttering in new area's
4. Check the size of your cache file before and after pressing the dump shaders button. If there's compilation data generated, it will grow. It can't hurt pressing it often.
Q:hey I tried it and it's indeed 5-10 times faster but when I restart AOC, it's not immediately ultrafluent. There still is some kind of mini-stuttering for like 1 sec or less everytime I first visit a previously saved area after starting the game. Is this normal ?
Yes this is normal, in fact this is as good as it gets. The client no longer needs to do all calculations but gets them from the precompiled results in your shader.cache.local file instead which is waaaay faster. Still it has to get them so it's normal to generate a small load, but nothing like what you experienced before so be happy and enjoy
Q:why doesn't Funcom provide us with a shader.cache.local file that contains ALL the shaders in-game so everything's smooth from the start ?
That is in fact their plan but it's not that easy: different cards and chipsets compile to different results so it's hard to make 1 file that has everything compiled for ALL videocards in the world. However, Funcom does plan to include shader.cache.local files with precompiled shaders for most known cards at around releasetime probably. In the meantime help yourself and make your own so you can play without stuttering !
Note: remember to backup that cache file regularly. If you reinstall the game or if a patch destroys it, you will want to copy your backed up version back to your gamedir to avoid going through all stuttering again
RAM
note: on a default 32-bit windows XP or Vista for that matter, no processes are allowed to grow over 2GB even though the maximum limit of a 32-bit process is 4GB per process. The game will simply crash when it reaches that size unless you make modifications. (you may be experiencing this right now). If and let me stress that only IF you have 3GB or more (4GB preferably) you can configure your Vista or windows XP installation to allow processes to grow over 2GB (at the cost of decreasing your OS's reserved kernel mem however...) so they no longer crash but instead run smoother. This change may be better OR worse for you. On page 4 (post 73) I explain how and why. Do this at your own risk and NEVER if you don't have 4GB of memory in your computer installed. Windows XP 64-bit and Vista 64-bit are by default enabled to allow up to 4GB for any 32-bit process do this so they do not require changes and your executable will not crash when it reaches 2GB on such an OS. Just make sure you have 3GB or more in your computer
note: 4GB is the ideal amount needed to run this smooth along with whatever other stuff you run on your OS (services, background apps, the OS memory itself) Vista will even use the extra memory to help cache other stuff. I have 8 and beyond 4GB you do not notice much more improvement in speed and smoothness so 8GB is NOT necessary for running ONLY this game while having all other apps closed. However having 8GB will help cache other stuff under Vista as well as allow you to simultaneously run a bunch of other windows programs. This is luxury however, not a must have. 3GB is must have minimum for smooth AOC gaming and 2GB means running the game at decreased performance. This is inevitable
note: the speed of the memory is completely trivial when compared to the actual amount of memory.Having e.g 1066 Mhz mem instead of 667Mhz will only yield a 1-3% memory read speed increase which you don't even feel or notice at all ingame
note: although increasing your RAM from 2GB to 3GB is in essence not a direct increase in fps but instead makes the game play and loading/zoning feel alot smoother, it should be noted however that if you lack alot of RAM your FPS will be affected through stuttering etc. Running the game with 1GB e.g will give such problematic play (enough to feel 'unplayable' Having 2GB is therefore a bare minimum for running at all while 3GB is the minimum for running smooth. 4GB is a good standard. More memory with Vista 64 gives you better HD access caching
note: Any 32-bit executable is by design limited to a max of 4GB physical memory usage and a non-modified 32-bit OS further limits it down to 2GB. If the 32-bit executable is marked for "largeaddressaware" (= allowed to grow to 4GB instead of 2G and the 32-bit operating system is set to allow largeaddressaware-processes to grow to 3GB instead of 2GB in mem size, then the executable can grow a bit bigger up to 3GB at a cost. (this is the reason in the first place while all 32-bit OS's further limit down all 32-bit processes to use a maximum of 2GB: because the OS itself can only address 4GB in total and wants to reserve 2GB for it's own (=kernel) operations and play it thus safe) For this reason the ideal situation is to have 6GB or more mem in your computer and have Vista 64-bit as OS. It safely has 2GB for itself and still 4GB free to let the 32-bit executable grow to it's maximum so the game feels like one big smooth train
note: as of today the game still has some technical issues that cause extreme drops in fps. All players are subject to this regardless their vid card (I talked to many ingame) Even with 2*8800 in sli running at low settings in the lowest resolution you still have this so it's not solvable by hardware. How bad is it ? Well it's like this: you stand still in a high graphs environment and notice 25-65 fps. As soon as you start sprinting or doing a 360° mouselook you may experience insane drops to below 1fps (= extreme stuttering) for a few sec due to the fact of missing precompiled shaders in the shaders cache database. EDIT: as of the april 19 build we now have a solution for this problem!! On page 6 (post 116) I explain why it happens and how to fix the stuttering yourself.
note: not all graphic cards appear to be "well compatible" with AOC. For example the latest badass 9800x2 series are known to give you trouble and low performance in many cases most probably due to bad driver support. all 8800series are rocksolid choices for this game as long as they have 512MB ram on them as an absolute minimum. Don't use a card with less memory !! All latest gen ATI cards such as 29XX and 3XXX series appear to be doing well
note: since 22 april and beyond, more GPU hungry stuff has been enabled in the beta-client. Therefore, as of now the sky is the limit since there is no longer any setup that can run the game at max settings. It is however possible with the latest gen hardware to achieve a framerate of 25-50 all the time without having to disable the game's beauty. I plan to implement a software tweak guide at releasetime once the video options are final (they keep changing currently in the betaclient)
2. (optionally) turn off AA (4-25 fps gain on average). AntiAliasing= a GPU hungry technique to improve the visual quality of a game even further
3. Run the game off a seperate fast disk or raid system (where you only install the game and put no other data or programs) This noticeably helps the loading times during zoning and launching the game
4. close all other running programs and antivirus before playing AOC and defragment at least twice a week. Use simpleconfig.exe in your gamedir to perform a compression while you sleep (takes ages!)
5. Run the game fullscreen!
7. Backup your gamedir before and after every patch

oh - we got new requerments for the game now ?
Basicly - If my 8800gtx and 5.4 rated PC can't handle Conan without some extra tweaking then the game isn't ready for launch. Its still not performing well enough for me.
4gb of ram.... Seriously .... The game has serious memory leak right left and center. Two loading screens and you crash. Thats great in a MMO game where you group up with ppl - just to find them dcing every 10-20 mins.... Seriously
Stability of the client is none existant atm. Its the basic of good gameplay - And Funcom can't provide it.
Thanks Terrapin54 for the informative post! I hope it helps those who are having problems come join us in game!
Cheers!

hehehe......sorry had too
the requirements are higher for beta than they are for final release. There are things that require more overhead in the beta clients, such as debuggers and uncompressed textures, and yes, on-the-fly shader compiling.
I don't know if I would suggest backing up and replacing the shader caches after a patch though, since the shaders themselves change often, and using cached data based on old routines would probably cause more issues than simply rebuilding them after each patch.
Also, terrapin, they aren't running the same build that we are m8. from what I hear there are quite a few differences. Posting build notes / versions in that thread might not be a good idea either
I posted this elsewhere but I'll repeat it here. I got this from the Funcom forums so I wanted to share.
STUTTERING FOR THOSE USING LCD MONITORS
If you're using an LCD monitor and experiencing about 5-10fps and major stuttering, try this:
1) Go into the debug menu (ctrl + ~ (tilde))
2) Click "Change Device"
3) Change "Vertical Sync" to ON.
The client will refresh without logging you off.
My system has run AoC very well since turning Vertical Sync on. The big problem is that this isn't a typical video setting in the game, so it must be done every time you run it.

You don't need 4 gigs of ram, I'm running very smoothly on High settings with 2 gigs of ram and vista 32 bit. My 8800GT and 4 ghz cpu chew through it easily.
This makes a massive difference in performance for me.
Quality information. Thanks for bothering guys.
Good tech-related post with explanations and solutions, gets sticky:ed for now.
(Also please try to keep posts related to problems and solutions regarding technical issues).
Thanks for the post, very good information. But, if I have to do any of this on launch day, FC failed.
What i read that it is usefull for 64 bit Vista systems because they suck up a lot of ram. got link in closed beta so cant post sry.
I just like to say very well noted post and very in depth. good worries are shown and right at hand, tips are good but not always working, its still to the individual gaming rig i guess.
Could we get a hardware forum for AoC perhaps?

You know it is sad but I think I have mentioned that Funcoms "recommended specs" are bogus. Why do companies do this? Also...are others, like myself, getting frustrated that we must continuely tweak our super fast gaming rigs just to run these games any more. We saw this in Vanguard and the first time I entered CB I was like...OMG my system can't run Conan? Remember my gaming rig could run Vanguard back when it was released on almost max settings and yet it couldn't handle AoC! What does that tell you? Think I mentioned this a few times in the past as well that if you think Vanguard requires a fast gaming rig wait until you experience AoC. So now you know why I was saying that because you guys are seeing it first hand.
AoC will eventually be a killer game...but it is not ready for prime time...not yet. Maybe...maybe 6 months or a year from now...but it is to early to be released. Just my opinion.
Taela, you seem to have missed the part about AoC beta clients having higher system requirements than the retail version.
Just because you could run Vanguard at max settings does not mean you should be able to run AoC at max. Vanguard was released in Jan 07. I would hope AoC looks better than Vanguard at release.
It runs just fine on my PC and I have not upgraded in the last year. Not max settings, but it still looks as good if not better than Vanguard on max settings. Maybe thats because I understand how to get the most out of my PC and the games I play.
---------------
Tested over a 115+ games since 1997.
Currently Playing:
Played(Retired): AOL NWN(91-95), UO, EQ1/2, DAoC, CoX, Lineage1/2, SWG(Pre CU/NGE), Planetside, Anarchy Online, FFXI, AC, Vanguard, D&D, AoC, DCUO, Rift, Eve, others
For those experiencing immense load times and lots of hardware lag, try going into audio options and unchecking "Enable Sound", I don't know why this works at all, maybe because of sound card issues, but my loads went from 10 mins to 30 seconds and I lost most of the lag I received when enter combat and rendering new areas. This on top of the shader dumping should help immensely. I now run at 35 fps or higher on the highest available nivida agp card, 1.7 gigs of ram, and a p4 single core 3.0ghz.
Something else someone mentioned was forcing your vid card's v-sync to be on if you are using an LCD screen. Go into your vid cards control panel and there should be an option there.
Thanks for the post, very good information.
to be honest i ve seen enough problems in the beta ( and i know its only a beta ) to cancel my pre order untill i see how well this game runs in a trial . lets hope they dont leave it too long or i may be happily playing warhammer and age of conan wont get a look in .
i m running a pentium duo 2.8 ghz nvidia 8600 gt with 3 gb ram... somewhere inbetween recomended and required specs . if (please note i say IF meaning that i m not saying it will be , i know what some of you are like )the released version is anything like the beta those specs are misleading .
I've played almost every MMO ever since 1997. Also fortunate enough to be in a lot of betas. I was in Vanguard beta as well. I saw first hand what happened to that game when they released it when it wasn't ready.
All the pre release hype that got stirred up. How excited everyone was. When are people going to wake up. The more you hype up a game the more you get disappointed when you see what a POS it turns out to be. For myself, I don't get pulled into the hype of ANY new mmo. I take all the fanboi speak and all the complainers with a grain of salt.
So it should be no suprise when I tell you from first hand experience... This Game Is Not Ready. And it will be months before enough bug fixing and polish is done for it to not cave in on itself on launch day. They better get their heads out of the sand if they think they are going to release in under 20 days from now. And yes I said first hand... I forsee another Vanguard coming. People aren't so forgiving when you frack up something they have waited and anticipated for so long.
Let's hope they can work a miracle in 20 days and I'm wrong.
as for warhammer, bleh, waiting 6 months (maybe 4 now that open b is running smoothly) is what i am willing to go waiting for the mandatory trapsing through posts until i find the truth (yes scully, its out there) by then i may or may not be playing, and well warhammer, unless aoc falls on its face, wont get a look. i can only stand one of these things at a time and bow my head to anyone playing multiple mmo's at the same time (and if so, you need help..................really)
can you smell that?!!...............there is nothing quite like it.....................the smell of troll in the morning............i love that smell.
I think this tool has been removed as of todays patch.
So, I'm half retarded and was wondering if my pc will run AoC decently.
AMD Sempron 3000+
1.81 Ghz 2GB ram
ATI x1300 512md vid card
turn view distance down to around 500k for beta you cant see the other gazillion k any way why load it it solved my left or right turn crashes
Some lead and some follow I prefer to stand beside!
