Twinings Posted July 25, 2011 Posted July 25, 2011 Looking at what PhysX can do to a games eyecandy - and playing Arkham asylum without - is kinda making me feel like im missing out on the atmospheric elements of the game, especialy as its a new build with eyefinity. Is there a way of enabling PhysX on an AMD card (6950 2GB) or by utilizing the onboard AMD graphics? I read on Wiki that a group of programmers brought out a patch that would re-enable PhysX in Games when an Nvidia card wasnt detected? To counter this patch, Nvidia implemented a time bomb in driver versions 196 and 197 that slowed down hardware accelerated PhysX and reversed the gravity, but an updated version of the patch removed all unwanted effects. Anyone know of /Used? If the only other route is to buy a cheap Nvidia card Wikipedia tells me - (series 8 and newer, with a minimum of 32 cores and 256MB of video memory) will do the Job - However, would 2 video cards from different manufacturers with both drivers running together (+onboard GPU) work or is this just asking for a world of pain!!. anyone doing it and care to post their success/failures Share this post Link to post Share on other sites More sharing options...
VaporX Posted July 25, 2011 Posted July 25, 2011 To get the nVidia and AMD to work together for PhysX there is a hack you must use, at least that was how it used to be. As far as I know, right now there is no way to make PhysX run purely on an AMD card, the issue is that PhysX is actually a CUDA prgram running and not a truly stand alone program.

I have seen people run AMD gpus (in crossfire lol) and an old nvidia card like a 260 or 9800 purely for PhysX, but you need to use a hack to get both drivers running at the same time. also for cf you will need plenty of x16 slots Edited July 25, 2011 by Muchoman1 Share this post Link to post Share on other sites More sharing options...
ivangela Posted July 25, 2011 Posted July 25, 2011 (edited) There are tutorials on how to run the Nvidia and AMD cards simultaneously on OCC somewhere. As I am going to try to do just that in the next week or so, if you haven't found them by then I'll be looking also and let you know on this thread A quick 5 sec search of the forums led to this article. I'll add to this another day! Oh and also a quick addition as to which nvidia card to choose ANother edit...This sticky is old but might help.

VaporX Posted July 25, 2011 Posted July 25, 2011 I would personally grab a GTS 450 or a GTX 550ti at around $100-$150 these should give you all the Physics power you will need. Share this post Link to post Share on other sites More sharing options...
Andrewr05 Posted July 25, 2011 Posted July 25, 2011 I have anoher 8800GTS (though I don't have the original box) that you can have for $45 if you want it. It's the G92 core 512mb version. Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted July 25, 2011 Posted July 25, 2011 You can get physx without an nvidia card, you can use one of the old Ageia standalone physx cards but I don't think they'd fair too well with the enhanced modern effects Share this post Link to post Share on other sites More sharing options...
Waco Posted July 25, 2011 Posted July 25, 2011 You can get physx without an nvidia card, you can use one of the old Ageia standalone physx cards but I don't think they'd fair too well with the enhanced modern effects AFAIK the newer PhysX API isn't compatible with the one that'll run on the Ageia cards.

firefox11 Posted July 25, 2011 Posted July 25, 2011 There was some work done a few years ago. I had a HD2900pro at the time and was closely watching the tech pages. I haven't heard anything since, however. A quick look turned up this article: http://www.tomshardware.com/news/nvidia-physx-ati,5764.html Share this post Link to post Share on other sites More sharing options...

Scrub that - Found it here http://www.ngohq.com/graphic-cards/16223-nvidia-disables-physx-when-ati-card-is-present-28.html#post82812 - But if you jump to the latest post its back to not working due to updates in later games and the hack not keeping up - seems like a load of hassle !!

Thanks for the links - but on further research its still a dark area - Maybe Nvidia cards are the only realy way of doing itive a couple of years left in my new 6950 2GB maybe ill go Nvidia then!
