I am getting fps drops on Batman AO with enabled physX on high.I play on a TV with refresh rate 60Hz so I cant take more than 60 fps either way but whwn physX is on high fps even drop to 30.With physX on normal it never drops from 60 fps.I think this is strange considering I am using the EVGA Gtx 780 Ti SC which is supposed to be one of the best cards at the moment.So my question is,cant my gpu handle physX on high or is it something else?Any help appreciated,thank you.

System information

Asus maximus V formula
i7 3770k 3.90GHz (OC at 4.60GHz)
Gskill trident 2x8Gb Ram
Evga Gtx 780 Ti Sc
Coolermaster GX 550w

When you use PhysX on high, the GPU has to render the scene AND do Physics. Two things instead of one. As a result, the GPU has fewer resources devoted to rendering, reducing overall performance.

Thank you for your answer. I understand what you say but the current GPU shouldnt be able to handle both operations without any limitation? So the solution is or use physX on medium or buy another card to run physX? I was hoping when I bought this GPU that I could run everything on maximum for a long time.

What do you mean by "FPS drops"? Exactly how low are you dropping? PhysX is going to reduce your FPS, by about 25% on a demanding game (as a rule of thumb, varies by a lot of factors).

I would take a look at some of your other Nvidia Control Panel settings, your AA level, your Ambient Occlusion, and see if there isn't some setting that's up a little too high. Keep PhysX on High though, because you should be running at least 60+ FPS.

All that was said here is right, but if you wanna a solution, you mat wanna spent some money on a low end video card ( 9800gt is ideal ) and use it only to render physx, it is very easy to be done and it increases your FPS by almost 50%
