Degrade of performance after GPU driver update #202

Closed georgtree closed 4 months ago

georgtree commented 4 months ago

Hello! I installed latest proprietary driver from nvidia: image image

After that, performance of xschem GUI degraded significantly, it is still good but previously it was much more responsive, instant even with large circuits. Now it doesn't depend on the circuit size, looks like driver limited the performance of GPU, maybe disable some hardware acceleration... And the most interesing thing - after some time if I focus on xschem window again, it works fast for just one second, and then start work bad - seems like it turn on/off some acceleration there. I understand that this is difficult to troubleshoot such an issue, but maybe you can point in the right direction? Thank you in advance, George.

Another interesting fact - when I turn on OBS to record screen, issue disappeared...turn on recording - issue is back UPDATE - not every time, some time there is issue, sometime no issue...madness.

I put FPS counter, when it works ok, there is 75, when not ok - 38... I took the video

Sorry, issue was in the whole system and particular driver, but I noticed it only in xschem, sorry again
