I' ve already addressed a topic regarding this among other things, but still i cant finish a match without having "server disconnected" middle matchs just to restart the game again and again.. My ping is always low btw.
GAME CRASHES ALL THE TIME
I had crashes to desktop in a lot of games (maybe 60%) but changing to borderless window mode stopped all crashes, and I played about 4-5 hours after changing with no crashes. That was on a MSI GE70 laptop though, but maybe worth a try -> Also I had all settings on lowest, with only 8GB RAM, RAM usage may be a bottleneck.
My specs are i7 6700k msi gtx 1060 6gb and 16Gb of ddr4 ram. It should not be a prob with my pc specs i think. I will try the way you said it and see. i cant finish a match without " server disconnected".
