A brand new video has come up showing a PhysX fluid similuation from NVIDIA.

RTX 50 series users can now gain access to GPU-accelerated PhysX effects in supported titles.
wait? i thought it was a hardware thing, so you're telling me it was there all the time and they just... turned it off?
That’s an excellent update. I thought this had something to do with the hardware itself and not just a software patch but either way this is great news
Great news! Initially was disappointed that my Steam copy of AC4: Black Flag wasn't compatible on my new 5070 ti laptop but since the update, happy to say I have downloaded and played the game successfully (Black Flag's my favorite AC).

It appears that NVIDIA has removed GPU PhysX support for all 32-bit games in its latest RTX 50 series GPUs.

This article shows the X58 and EVGA RTX 3080 'Black' Gaming GPU performance. The article consists of 23 benchmarks across several games and synthetic benchmarks with multiple resolutions. The article also contains power consumption, more in-depth information and comparisons for the X58 vs modern platforms.
Physx is a marketing gimmick.
gotta love the power of gpu's.
This is why I expect the next console generation to feature an extremely power gpu with very little cpu support, all coding for physics, ai, etc will be done via opencl, compute shaders, and cuda.
I want something like physx on ATI cards
I thought that was gorgeous... im no expert but thats pretty cool its dynamic
Still wondering when games will really start being able to do this kind of simulation in realtime in a normal game, not a techdemo. Hardware apparently has a ways to go before processing will be wasted on making proper shadows, water, fire, smoke and other particle effects look real.
