Kuronin Posted December 26, 2011 Posted December 26, 2011 Hey guys, what's up? I've got a question about PhysX, more specifically, the function and performance of having a card dedicated to PhysX. I'm not really sure how the system works, so if someone could explain it to me, I'd be grateful. I have a GTX 260 on one rig, and a GTX275 on another rig. I have been entertaining the idea of purchasing a 400 series card. And moving the GTX260 as a dedicated PhysX card for my GTX 275 rig. My question is, would there be any noticeable difference in performance for an obsolete card. Currently playing: Sykrim Battlefield 3 Dead Island Bulletstorm Thanks guys!

Boinker Posted December 26, 2011 Posted December 26, 2011 You would have to test the setup to see what happens but in my experience with many games and benchmarks it does not make a difference. Play the game and see what happens. Share this post Link to post Share on other sites More sharing options...
Black64 Posted December 26, 2011 Posted December 26, 2011 It is a function that allows nvidia and some AMD graphics cards to calculate complex particle / object interactions in real time. For example, having life-like clothing on player models, realistic fluids and collisions.

Waco Posted December 26, 2011 Posted December 26, 2011 I've yet to find the "killer app" that makes me want to use PhysX. Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted December 26, 2011 Posted December 26, 2011 You can end up bottlenecking high end SLI/xfired cards with something less than a GTX 460 1GB, but for what you have, you'll be fine. Share this post Link to post Share on other sites More sharing options...
CoachAub Posted December 26, 2011 Posted December 26, 2011 Is it possible to use an AMD video card and then add an Nvidia card for Physix only? The 990fx mobos allow for either brand cards. Share this post Link to post Share on other sites More sharing options...

No, if phisX detects a non-Nvivda card it disables it. Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted December 26, 2011 Posted December 26, 2011 You can use a hack to enable PhysX with AMD cards, it just means you'll need to install an executable and select the SLI hack or the normal Windows boot before loading Windows.

d6bmg Posted December 27, 2011 Posted December 27, 2011 @OP: it will be waste of money IMO. There will be very little improvement in the performance that you can't even notice normally. Share this post Link to post Share on other sites More sharing options...
