4.19 very laggy in editor?

4.18 was so smooth for me, now 4.19 lags very hard in the editor, basic starter scenes that were running at 120 now run drop out to 10 fps every 10-20 seconds for a couple seconds.

Same thing here, waiting for a fix until then going to go back to 4.18 (which runs as smooth as butter).

My PIE window freezes. That may be an OS issue.

But Stat RHI drops the framerate quite a bit as well.

120 fps drops to 106/108.
110 fps drops to 90/95.

I’m not seeing that in 4.18.
