Garry's mod lag issues

Sometimes lag is occurred for about 3 mins and then disappeared. It really bothers me.
it never lagged like this before. I thinks spec is not the source of this problem.
I tried run Garry’s mod with dx7 and it still got lag
I think there are some problems on system like config or console line.

please help me.

Hi ddok1994,

Is it FPS lag or connection lag.

it’s fps lag imo

Have you got addons installed?
if so try moving then out or if there from workshop to disable them

I just realized that it isn’t problem of only gmod. It happens at all 3D games

Try updating drivers.
