Hammer is verry laggy

My hammer has never been laggy at all, then a few days ago, it got so slow I couldn’t do anything, as if I was playing a game at 5 FPS.
I defragged, but that didn’t do anything, it’s been like this now for a few days…
Thanks if anyone has an idea on what’s the problem/how to fix it.

Update your video drives?

Has it been with the same .vmf? If so, try opening up another one and see if the same problem persists.

Up to date already.
It seems to be working just fine now, No idea why, just randomly stopped.
Oh well, sorry about the thread, and thanks.
