Final 10 seconds

Hey I'm frequently getting much more lag in the final 10 seconds of my games than in any other part. My cursor was stopping short of where I was moving it in a recent game for example, that led to losing an extremely winning position. I'd recommend to not have special features pop up in those final 10 seconds to indicate the game is about to end, they seem to cause lag.

Or at least give an option to completely turn off anything that could cause the mouse or screen to lag. Perhaps something like this already exists?

Don't ask man, my friend have almost lost 3 games because of this. He somehow Ctrl+F5ed very quickly and did +M2 in 0.5sec left. Maybe those features trigger something that overload and crash/lag the system.

The final part of games is usually tough in terms of network utilization.
