CUDA on Cloth seems very slow

[Zakkorn]

Hello,
today I tried something with Cloth and I wanted to try CUDA as recently I got an RTX (3090) card.
Whenever I enable it it takes double time in comparison with the OpenCL.

I have put the latest CUDA dlls for the TyFlow.

I dont understand it looks like the card is useless.

Is there anything I missed or do wrong, I am confused.

I'm not sure I understand the issue.

The CUDA cloth computations are for mesh collisions. OpenCL is for the actual cloth motion itself (and potentially particle collisions, not mesh collisions). They're not the same thing and by enabling the CUDA collision solver the sim will take longer, yes, but the sim will be much more accurate.

So it is normal that when I enable it, that will take more time. 
As, if I understand correctly, it will add more calculations for more accuracy.

Thank you for the answer.
