Fallout4/Proton/GE

I run into Performance Trouble, On Proton 9.04 ~55fps little laggy On Proton GE 8.32 ~144fps few microlags remains but Crash as Image in the post.... (Simple start command won't cap the fps don't know why peaks above 1000fps) On Proton Experimental ~55fps again a little laggy On Proton GE9.x and GE10.x ~55fps and laggy I am on cashyprotontest And now the same as ge 8.32 in fear of the crash ~144fps few microlags remains but Crash as Image in the post.... (Simple start command won't cap the fps don't know why peaks above 1000fps) I wrote 55 fps but some of them were above 60fps and some were below 50fps Is there a way to know what's working fine without testing a lot and risking a big save file?
