Does anyone in here still plays CSS? I got a weird issue. My game skips a frame with every loud gun shot even though FPS doesnt drop. It feels like stuttering whenever I, or anybody who is close to me, shoots a gun. It doesnt matter if I have 300fps or 100fps it's always happening the same way. It gets really bad when people are spraying around, especially with P90. Only way to stop this behaviour is to turn on VSync but then I have really bad mouse input lag. Other games work just fine...

My system is Linux Mint 19.1, default kernel 4.15.0-48-generic.
