I tested the scene on a dual RTX2080 and a single RTX3070 and get the same amount of FPS.
I want to check the “enabling omni.physx.flatcache extension” hypothesis, but it seems this is not up to date as of November. Any idea how I should be activating this in Create 2022.3.0?
Hi there, that is what I am trying to do, but I could not find the extension in the launcher, nor could I find any settings for that in the physics settings in create.
Yep, works great. I’m getting 30-50fps on my 4080 with flatcache on. 23 with it off. You’re likely hitting a limitation with the GPU. Unfortunately I don’t have a 30 series to test on.
If you are limited by the GPU power, you can also try to let the simulation run on the CPU, on the PhysicsScene try to disable the GPU Dynamics and set the broadphase type to ABP.
Additionally you can run the simulation asynchronously, again on PhysicsScene in the advanced section set the mode to asynchronous.
But it does not sound right, that the perf is so low for that low number of bodies. Will check the perf.
Yes, I already filled internal Jira to investigate the TGS instability and the GPU perf on this scene. CPU simulation with PGS seems to get best results on this particular scene, but we are investigating why the other options are not viable. Sorry about that.
