Valve Hammer Editor Lag

[Caluminium]

I am experiencing lag in hammer, when I click, select or move .etc something it has at least a second of delay, even when I'm clicking on nothing. I've tried using VisGroups and updating my drivers, with no success.

The video shows the comparison between my map in progress (it's about 1/4-1/5 the size of phlames) and is only showing one VisGroup area, phlames, and a map with only one brush in.

Any ideas?

Raise priority on Hammer.exe in task manager.

Moving to the second core+ would also not go amiss.

That should fix it, but if not, check your processes for something that's locked or otherwise eating CPU, and the old stand by: reinstall graphics drivers.

Oh yeah - one more thing - zoom in on the other 2D panels (tap a number key). The 2D panels sometimes eat a lot of Hammer's alloted CPU, if they are zoomed out, for unlike the 3D panel, which is OpenGL, they are in software mode.
