Low fps after patch

Today I lauched the game and without any changes to settings or my HW/SW I was surprised of having only 20-32 FPS with spikes to 40-60 .. before last patch (after previous and before that) I was easily reaching 80-120 FPS .. MP4 on Sonoma and Moskow ...other sims are running fine ..
anybody with the same issues ?
Thanx
