Thanks a lot for your answer, really appreciate.
I’ve tried to desable those, but sadly still have the same problem.
Regarding memory, (I had a 3090 with 24) and now a 5090 with 32 go. I’m using them all + half of the 32 go of shared memory.
However with a resolution of 7680x2160 things are working fine, also with the 32 go of dedicated fully used and a 8 of 32 go used for the shared.
It’s a very important project for me, still trying to find a solution.
Thank you!
