OK so I got busy and stopped playing TF2 for about a month.
Come back. Seriously long load times, and random shuddering.
No virus
Not an old comp (I5 with 5770 and 12 gb of ram)
all updated, no out of date drivers ect.
Other games like CS:GO play fine load fine ect.
Anti-virus ignores Steam entirely.
checked my printer cable.
Also no dust. My comp is dust free.
No heat issues either.
Anyone?
