Hi. It’s a bit confusing to determine if the new RTX 5090 GPU is compatible with IsaacSim. From my understanding, Isaac Sim is built on the PhysX physics engine. Given that the new RTX 5090 graphics card explicitly states it does not support PhysX, I’m curious whether this will cause compatibility issues for Isaac Sim?

Additional Context

(Add any other context about the problem here)

Could you please share the specific statement or source where it says that the RTX 5090 does not support PhysX?

Hi Vick, thanks for your reply. Here are some links, though I didn’t find the official link.
As refer:

That’s confusing me.
Thanks for your reply.

This is correct. All 50 series cards no longer support 32bit CUDA or 32bit PhysX. Only 64bit. But the 32bit is very old. Isaac Sim 5.0 is not affected
