I've got an odd bug... I could be having 30 FPS in-game just fine, while in first person mode, however, once I get into the Map Mode, to command the groups of units, the responces from the mouse seem to be lagging. I could for example, drag a selection box with the cursor, and the cursor would move fine, but the selection box would only appear 3 seconds later, then disappear (as per unit selection) and the units would only appear as selected about 3 seconds later.
Another example is that, I can quickly select all the groups on the map using keyboard shortcuts, they would get instantly selected, however, when I set a waypoint, it does take a few seconds to be marked.
I'm not sure what the problem is, as I've looked around and tried several things, like turning off v-sync, and enchanced mouse pointer.
I've got a Quad Core AMD Athlong 64+ 2.6ghz, Nvidia GT240 1GB, and 4GB RAM. I am running Windows 7 x64.
