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
