I’ve recently been having problems with my regular Source SDK, namely of course, Hammer.
It didn’t used to be this way before either. It’s just not the 3D view lagging, everything is; and the program seems to like to hang on doing a single task for a few minutes, then goes back to its laggy state.
However, I don’t have this problem at all with the L4D SDK. It’s perfectly fine.
I’ve tried defragging it (took about 10 seconds) and verifying it’s integrity. After I did that, it proceeded to reinstall itself over and over whenever I restarted it. I seemed to have stop that, but still can’t find a solution to this.
