Huge FPS loss after update to v0.20

After updating game from v0.19.4.2 to v0.20 i experience a huge fps loss, e.g. Gridmap: was 110-120 fps, now its 55-60 fps. Settings are the same (high). Interesting is that whatever graphic setting i change it has no impact on game performance. Config: i5 4690k, 12GB RAM, GTX 1080. Any ideas? Thanks in advance.

 

I have the same problem, massive loss of FPS and lowering the setting does not improve anything, stays laggy and fps is the same

 

I noticed it too, especially with traffic before it never dropped below 70 now there are moments where it drops into the 40s

 

yeah im at max 40-50 fps now. sucks tbh :/
