Playing CSS, if a Toast pops up, my FPS will drop within the game, but with netgraph showing, I am getting more FPS' it thinks, if I turn off Steam Community obviously it is fine.

I am now using Mesa drivers instead of AMD's own and seem to have better luck with them.

The game is locked to my refresh rate regardless of vsync, if that is anything, I assume the game is running a borderless window.
