Physx on a radeon?

NagelFireNagelFire Member Posts: 409

Alright, so my old card was an Nvidia 8800 GTS and it had Physx on it (obviously).

I just replaced it with a ATI radeon 5850 and I was wondering if ATI had anything like Physx.  I cant play dragon age anymore because it requires Physx, and the game I want to get, Arkham Asylum also requires physx.

A mod or something mabye?

    You can play Dragon Age and Arkum Asylum on a Radeon.  The game's don't require Physx, its merely an option. The differences are minor at best, and both games still look outstanding running on an ATI card.

    You used to be able to use a secondary Nvidia card to run your Physx while your ATI card did the GPU work... however Nvidia had a sissy fit and changed their drivers so you have to have a Nvidia GPU active for Physx to work.  

    HavocFX was going to be ATIs answer to Physx, but last I heard Intel shelved it.  So your pretty much stuck with Nvidia for Phyics hardware acceleration.

    As I understand it, if you use Windows 7 there is a community patch that allows you to use old Nvidia drivers so you can use a a Nvidia card in conjunction with an ATI card.  I'm not an expert on it by any means though, I'm sure if you look hard enough you'll find more information on it.

    I am quite sure PHYSX is owned now by NVIDIA,i could be wrong,but i think so.

    I cannot see any game holding people back,because they know full well many do not have NVIDIA cards.

    The new Physx workaround patch 1.02 for Radeon + Nvidia cards supports Windows XP - Win7 and nVidia driver up to 195.x

    http://physxinfo.com/news/942/hybrid-physx-mod-1-02-195-xx-drivers-and-win-xp-support/


    This patch bypasses Nvidia's hardware check that disables hardware Physx if it detects ATI hardware, allowing you to use the Nvidia card for physics. AMD is pushing for an OpenCL physics engine (through Havok or Bullet) but that's still a long ways out so as long as this patch works it's the best option.


    Games that support hardware Physx will run on Radeon cards with lowered software Physx anyway, if the game is giving you Physx errors you probably just need to install the Physx software http://www.nvidia.com/object/physx_9.09.0814.html


    If you have trouble with bypassing the hardware check, you can try older versions of the Nvidia driver/Physx software (185.62 or earlier has no hardware check, not sure the equivalent Physx release)

    Nvidia owns physx. No game will require physx supporting gfx to work, if you don't have nvidia card then the effects are made with cpu.

     

    Ati supports havok, bullet and pixelux based physics via open cl. You shouldn't concentrate on physx too much, it will die totally soon enough. Closed system with very little 3rd party supporters will not survive against open source alternatives.

    actually nvidia is shooting itself in the foot all the time now.

    there is a new motherboard chipset in the works called hydra. the idea being you could run ANY graphics cards together-     even mixing brands/series! however nvidia is trying to kill it by blocking it at the driver.

    www.vizworld.com/2009/11/report-nvidia-plans-block-lucids-hydra-chip/

     

    running a dedicated 200 series card for physx/cuda and using the superior 5000 series ATI for grfx could have kept nvidia afloat.

    i suspect that between intel making a HD capable onboard chipset and ATI/AMD dominating discrete cards nvidia is on the way out. if not now then when AMD hits 15nm and starts making integrated cpu/gpgpu units. it will be the final wood screw it the coffin!

    Yea, off-topic but there really isn't a long term future for Physx. Most games are designed with consoles in mind and Nvidia has no marketshare there (ATI powers Wii and Xbox 360). Nvidia should be supporting an open physics standard since they are actually far behind in market share in the overall picture and very few devs are going to use hardware Physx when only a small overall segment can use it. They are actually hurting the PC market by trying to pin it to Physx which will never be supported because it isn't in consoles, at least an OpenCL solution would have the whole PC industry behind it.


    An OpenCL engine would run on Nvidia, ATI, Intel Larrabee, AMD Fusion and regular Intel and AMD CPU's (which both have/will have so many CPU cores that enhanced physics is the only thing to use the cores for).

    Im pretty sure the old Ageia physx boards will work with ATI's.  The only problem you might have is getting the original drivers for them.  Newegg doesnt carry it anymore, but you can find them on ebay fairly cheap.

    I own a PCIe version of the physx board and the only drivers you can download are from nVidia's website.  Not sure if this will jive with your ATI board or not, but they are seperate drivers from the standard nVidia video board drivers.

    I know first hand that regardless of ATi or nVidia card, Mortal Online requires Phys-X software to be installed or it will not work.

    PhysX is most likely going to be phased out, and its both AMDs and nVidias fault.  AMD is not making it easy to run PhysX on AMD GPUs because they know they can phase it out with 2 good GPU iterations.  nVidia initially did not want to support AMD GPUs which gave AMD reason enough to turn it around and look good.  Bullet and Havok Physics have become the standard, PhysX has just become niche.
