Why do NVIDIA PhysX decrease my FPS?

[Takayuki_147]

I have my monitor acer s276HL 60hz monitor and then i play WARFACE then there is an PhysX option i set it to HIGH and then all of my video settings are high with Anti-Aliasing and it drops like 20 average FPS i did medium settings and then enable AA and physX but it just has a 30 FPS average...it there someone who is the same as my situation?

If you only have one card and use it for the game + PhysX, there will be a frame rate drop.
You can add another card (doesn't have to be the same) like an old GTX 460 with your current card.
Set the second card as a PhysX card (through nvidia control panel) and your fps wouldn't drop that much.

As ianyanian said use a dedicated physx card to decrease the frame drops. Just make sure the card does not bottleneck the bigger card or u'll end up with worst performance. For example if you have a gtx 960 minimum use a 460 and above as long as the card has more than 300 Cuda cores and memory is GDDR5 you're gold. What are your system specs ?.

On the forums they say the same thing looks like its not optimized a lot of people are having the same issue.

Turn it off for now and if you can't just put it on low and if you have a weak cpu overclock it to alleviate fps drops.

My question is what type of video card do you have? If it's an AMD card, then there's your answer; they struggle to run PhysX. If it's an Nvidia card, then the game itself must be too much of a match graphically for your card. The same thing happens on Borderlands 2 in intense scenes with a lot of PhysX particles on screen.

So what video card to you have?

That's typical for PhysX. Usually it is something you will only want to enable in games when there is extra grunt on your gpu; means on high/very high/max out setting excluding PhysX you can get high frame rates. Because with (gpu) PhysX they will try to callulate some of those visual effect physics in real time instead of rely on scripted behaviour.
