Fps drops on Batman Arkham Origins when physX is on high wih Gtx 780 Ti on 1080p

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.

  1. 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.
  2. 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.
  3. 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.
  4. 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%
  5. if you want everything on max, I found out turn off dynamic shadows and the game runs consistently 60 fps even with physx high
  6. Physx is affected also by game vidual settings (lets assume a light reflection on the floor. If you suddenly have 50 particles flying out of something, the light and the reflections will hae to be calculated on those as well).

    Physx is a strange beast. Depending on its implementation it can have little effect or a lot. Most people use a second lower end GPU to run Physx if they really want to have them on high, without sacrificing visual quality.

    Also, are we sure you PSU can handle your PC?
  7. Simple answer is Physx takes a fair amount of horsepower when set to high, which is why your FPS is lower with that setting and why many people get a lower end Nvidia card dedicated to only Phyx calculations.

    With Batman Arkham City, they did not recommend using PhysX on high without a dedicated PhysX card. I doubt that changed with Batman Origins. Without a dedicated card, your performance won't be optimal. Heck, in Batman Arkham City, even with a dedicated PhysX card, performance was not good with PhysX.

    You might also consider using adaptive V-sync, instead of normal V-sync. When your FPS drops with normal V-sync, it tends to drop from 60 to 30, unless the game supports triple buffering, or you use SLI.

    I remember playing this game when I had a 780 ti & remember some drops. These type of things happen when PhysX is enabled on high.

    I remember lowering some other settings because i like the PhysX on High...
  10. I'm going to download this game via steam and see how it plays on my current system.
  11. Are you using TXAA high?

    Using FXAA will give you a huge increase...
  12. I don't think FXAA would help, even on FXAA my 970 still couln't handle with high Physx
  13. Will FXAA High @ 1440p max settings PhysX HIgh I'm getting 140+ fps dips to 120 or 130...

    With TXAA HIGH I'm still not going lower than 60 fps, generarlly getting around 70 avg with max of 90.

    The Titan X is powerful however based on my memory my gtx 980 had no problems maintaining a 60 fps with the settings maxed out using fxaa...

    I'm guessing alexsocool69 is using different cpu than me...
