This is great! I’m happy to see someone is as desperate to get this working as I am. Unfortunately I can’t be of much help as I know nothing of coding, let alone PhysX’s inner workings however I’m curious how you managed to get 60fps Max with a Kepler GPU. My old 670 FTW edition would drop HARD in heavy combat despite numerous “workarounds” and tweaks to ini files and dlls.
By the way PhysX is open source now which I’m sure should help at least a little bit although I don’t doubt it works a lot different than what we see in BL2. I think BL2 runs on PhysX 2.XXX while the latest is 4.0 speaking in terms of the SDK. Some games also use PhysX as the entire physics engine (Arma 3 for example) so I wonder if those would provide any info to you.
I’ve tried everything to get it to run decently on my 670 and my 970 with no luck so I’ll make sure to check back every now and then.
Good Luck!
