Plutonium

is there any way to replace any other camo with this one?

So recently I started notice that my game is lagging pretty bad and it sometimes I can get around 10-20 fps in-game, and same with freezes (Also my CPU doesnt reach 100% cause I did cleaned my PC like a 2 weeks ago).

Also my game crashes almost everytime while game or when im joining random server:

Honestly I dont know why its lagging that bad and im really struggling to play.

My PC specs: GTX 1060 6gb, I3 8100, 8GB ram, 1TB HDD
