Oh, let me add that RC5 is not exactly the most exciting thing you can do on your computer, but it helps out TA quite a bit in the stats. The best think you can do is let it run as much as possible in the background, and forget it's there. It shouldn't cause any performance degration at all. If you do notice some lag in a game, let's say, just disable it before you play, and then launch it again when you're done. I'm a big Quake3/UT guy, and leave it running. I haven't noticed a slow-down at all, but some people find it to lower their gameplay by a couple fps, but that's it.
