Whenever I pass from a path with textures that have too many lines or entities, I get lags which never stop happening!!! I discovered it when i was playing on italy2 map and got lagged when i strafed while seeing the lines but didn't when i strafed looking at sky :p
Anybody can explain it please. I also get it when someone bursts a granade near me and I look at it :p
it happens even when i play on my own server.
