Any reason why this new version (5.0.0) is glacially slow and significantly slower than the previous version on MacOS (M1 Max 32Gb, Sequoia)? UI, selection, scolling is extremely laggy (at least 1 second delay for any drop down or UI element), zoom and pan is extremely stuttery and lags even if only 2D is displayed.
Not hitting any memory limit, still free memory with zero swap.
Sampler has always been a bit chuggy on MacOS but this is a significant performnce decrease.

Hello,

Can you share with us your log file?

Did you enable the Path Tracing mode?

In rasterizer mode you should not experience slowdown on M1 Max, we have to investigate with you.

Hi,
It shouldn't be that way. Can you share your log file ? (go to help menu > Export log)
A video showing the issue could help us too.
