I just got this game, and I'm liking it so far. But I've got a problem. Before, it would play at full speed, or at least at a playable frame rate. A few hours down the line, though, and the game is having noticeable slowdown for what seems to be no discernible reason. I've got Windows 7 64-bit, and I've tried running it at the various sizes from 1X to fullscreen, with AND without VSync, and it still has slowdown. I've seen others have this problem as well (not on this forum, however) and haven't been able to find a solution. If anyone could help, I would be most grateful.

I noticed this too. For me, it turned out that the slowdown was caused by me switching to using a gamepad instead of the keyboard. For reasons I still don't understand, playing TAG w/ a gamepad makes it run at half-speed or so for me even though it's running on a fairly powerful PC. When I switched back to keyboard the slowdown went away.

I really wanted to use a gamepad, though, so my final solution was to configure TAG to respond to keyboard input. Then, I configured my gamepad to emulate keyboard input using a free tool called JoyToKey. Now everything is great!
