Recently i was wondering where does the latecy comes from. It was not consistent so i thought it was connection issue and server sided but then it kept happening even vs bots.
It turns out that if i alt tab few times the game starts choking untill i restart it which causes connection-like lag in game. Huge delays to input and units become generally unresponsive. If i don't alt tab that problem never occurs. Tried both borderless and real fullscreen, same thing.
The que times sometimes are longer than 5 minutes so not being able to alt tab to browse internet in the meantime is really annoying.
