So i actually just tried some settings I found a while ago and they did give me a slight bump:

Edit the bootconfig file with the first 2 lines being :

gfx-enable-gfx-jobs=1
gfx-enable-native-gfx-jobs=1

edit the launch parameter in Steam to include :

-window-mode exclusive -screen-fullscreen

*Edit : Went from 17-22 to 19-33 (also turned off steam overlay and VR)
