Hi,
I upgraded to the 367.27 driver yesterday and when playing CS:GO my FPS suddenly dropped to ~15 and the game became very laggy and unplayable. I played 4 matches and this happened in 3 of them. The thing that triggered it was when I died or when I was buying stuff at the start of a round, and the only way to fix it was to quit CS:GO and restart it. Reverting to the 361.45.11 seems to fix the problem.
I have also reported this problem to valve here: [nvidia 367.27 bug?] FPS drops to 15 randomly after dying or buying. · Issue #1116 · ValveSoftware/csgo-osx-linux · GitHub
I have an nVidia GTX-560Ti and I am using Linux kernel 4.4.14 on Slackware64 current with xorg 1.18.3.
