I think I'm going to start another topic specifically on this - trying to optimize PhysX in Borderlands 2 to get it running better on CPU.Is it even possible to remove certain PhysX effects? The water effects absolutely destroy my i7-950, particularly in Caustic Caverns and Bloodshot Stronghold. In both of those cases the main problem is large bodies of water that are pointlessly modeled with physX effects that do almost nothing to enhance their realism (whirlpool, caustic lake). It makes a lot more sense to only model flowing water (broken pipes), or even just skip the water altogether since it doesn't look all that real to begin with, more like weird flowing goop in most cases. I'd gladly give up exploding barrels with goo inside if it meant I could keep the fabric and particle effects enabled without game-destroying slowdowns on certain levels.
