I was playing C:S perfectly fine yesterday until I got a driver update last night. I thought "hey its a new operating system, there are probably a bunch of issues with nvidia drivers so they issued an update. Fuck it, I'll update."

The only problem is that if I enable G-SYNC on windowed applications(because the Fullscreen option in C:S is actually Fullscreen Windowed), I get *insanely low FPS.* I'm talking AT MOST 12-15fps and I have an overclocked 3770k and a 980ti SC.

Then when I disable G-SYNC for windowed applications, my FPS goes back to normal. Now the reason I am posting it here is because C:S is the only game this happens with, so idk if it is more likely to be a CO issue or an NVIDIA one.

I plan on downgrading my drivers until this is fixed.

Hey Andrew thanks for getting back to me. Unfortunately I downgraded my Nvidia drivers to 353.62, which solved the issue so I can't tell you if your solution works.

I couldn't go too long without playing C:S :p
