Wondering if there's anything that can "translate" the Physx effects kinda like how dgvoodoo has the Glide thing? Basically if its not an Nvidia card it gets passed to the CPU and will lag extremely hard when stuff like smoke/steam or particles using the Physx engine are on screen. I tried DXVK but it didn't seem to help.
Doesn't PhysX already work like that? I only have the original release of Mafia II for reference and I distinctly remember PhysX option working on non-NVIDIA hardware. If my memory is right, I recall Terminator: Salvation also having dependencies on PhysX libraries, but I'd have to recheck to be sure. No idea about Batman, there are multiple games which title start with Batman Arkham.
I suppose some games could have artificial limitations and not use PhysX if non-NVIDIA card was detected, but I don't think PhysX itself has limitation that it wouldn't work on CPU if nothing else was available, even NVIDIA Control Panel has distinct setting to choose whether it should run on GPU or CPU.

That's exactly OP's problem. PhysX was deliberately made in a way that it's unbearably slow on anything that isn't nvidia.

It's not an artificial limitation. The amount of physics effects in GPU mode was/is too much for a CPU to process and have acceptable performance (You can force it in the driver control panel to be processed by the CPU though).
The reason that mode is limited to nvidia is that GPU-accelerated Physx uses CUDA, which non-nvidia parts don't support.
The only option is to disable GPU PhysX in the game, which switches to a non-accelerated CPU-only Physx mode with reduced game physics.
There used to be a site that kept track of physx games:

AFAIK all retail games that support GPU physx also have the option to switch to a lighter CPU mode.
@OP
Maybe if there was a way to run CUDA on non-nvidia cards, then perhaps GPU physx can be made to work.

Yeah, I didn't read the original post right...
Still, can't say I found PhysX particularly performant even with a real NVIDIA GPU. Maybe if you fork a thousand for it it's better. Talking about mid-range GTX 750 Ti from 2014.
