nVIDIA PhysX broken?

[hawtdawg]

I have both games. Say where and at what settings you experienced this. I can try it with or without SLI.

Those floating purple things in Pre-Sequal pretty early in the game. Whenever I get in a fight with one, my FPS absolutely tanks, like literally into the 20's, when the majority of the time the game stays over 100fps.

I do have Windows 8.1, don't know if that matters.

Mafia 2 doesn't use the GPU for the extensive cloth physics with a single GPU and uses the CPU. However, it uses the GPU for cloth physics with a PhysX discrete card.

you cant run SLi and PhysX at the same time unless you have a dedicated card for GPU PhysX.

What?

What?

PhysX doesn't always play nicely with SLI, seeing as only one card does the PhysX whilst both render the image. Sometimes microstutter is the least of the problems.

This is mostly what I was saying. I should have been more clear
