Updated> It solved the problem when I switched from borderless to fullscreen... "Only" some studdering now.
So, i have been away from computer for a couple of days. When I wanted to game today the game was deleted from my computer, so I downloaded it... again. Now I crash within5 min. My loadingscreen stays on even when 100% and game runs in background. When I finally join I am invisible to the enemies and cant kill or capture. Then im pulled back to spawn (rubberbanding?) Then I respawn as normal and can do what I do, only to have the game crash on me.
Im on i7 4710HQ @2.5Ghz
