So it looks like CS:GO has been having some issues. If you are unable to get the game to run properly add -windowed parameter to your launch options. This issue has been affecting users on all platforms. I just tried and it works now.
Edit - Adding -nojoy works even better

I'm more unimpressed by the massive performance hit in recent updates of CS:GO along with DOTA2. I have an ancient Phenom x6 3.2 Ghz w/ GTX 960, 8 GB of RAM on Arch w/ the latest Vulkan-enabled Nvidia drivers on a lean OpenBox setup. Both games used to run with a much more stable framerate and other games have actually improved performance wise on the same system.
Really? That is not good. I have not noticed anything getting worse, but I know how annoyed I would be if I did. Hope your troubles get fixed, man.
Did you try "-nojoy" instead?
That works even better! Thanks!
