Well, weirdly enough, after a few more tests last night, and looking at the f11 menu to monitor, everything was running smoothly. Very minor stutters here and there, which is expected from any RTS. However, nothing like what my friends and I were experiencing the first night. We didn't have time to play through an entire game, but I'm optimistic things will work tonight. It's possible that since my friends had fresh installs, simply restarting their computers smoothed things out, but who knows. I'll reply one more time after we play a full game tonight with an update.
