I have Windows 8 running Radiant, clean computer, just installed the software.

But when I make maps, the camera moves very choppy, like one frame per move, and its really slow. Every time I right click and drag to move the camera, I get really annoyed because its hard to see everything and design when it isn't smooth.

I was wondering if anyone has any suggestions on getting the camera to move smoothly. I have gotten it to slide nicely across the map and around my designs, but right now the camera is really laggy. Is there any option in the Preferences panel I can edit?

Thanks in advance.

Have you tried turning on cubic clipping, what this does is only draw the part of your map you are viewing within x amount of units. If my memory serves me correct the toolbar icon looks like a blue square but it you mouse over them it should say in the tooltip. You can edit the distance drawn from the camera (your point of view) in the preferences.
