when using mods it puts a lot of strange on the cpu,  peteru callouts is unstable  i  also would turn off sync v  that should improve it  fps abit
 
also your cpu is only max at 3.6ghz with all the dlls on there it will be pushing this to the max eg that's y your frames are reduced
 
but i would do some long manual checks remove all the call-outs apart from assorted call-outs  and try that you should see the difference
 
this one is a big cpu user oj scenarios
 stop all  ambient events  or leave them on i use lspdfr comes alive its all ambient events is so good
