Crazy high system and compressed memory disk usage only when playing Gmod?

windows 10, hasn’t happened before I upgraded.
upwards of 1gb, leads to drastically decreased performance in everything when i have gmod running.
this literally only happens with garrys mod, no other games.
any solutions?

since you’ve told us nothing about your system specs:

is the handbrake on?

no but Ive turned on the ebrake

some shitty AMD processor
radeon HD 8330 shit edition
6gb ram
windows 10
some random ass 600gb hard drive
