That's pretty much what changing the resolution does for 2D and "2.5D" games. You can only see more of the screen as the content in the game can't adapt. I can happily change the resolution for all the other old C&C games, including Red Alert 2, which I believe was made with the same engine as TS wasn't it?

Does anyone know if the actual game resolution can be changed for TS? Any alterations I make to it, either in the sun.ini file or the game itself, seem only to change the dimensions of the screen. The native resolution of my laptop is 1366 x 768, so at this resolution the game units are tiny. Any ideas?

Hey, check out this solution, it worked for me with fixing the lag problem. It isn't perfect as there is some flickering between the game and the desktop, but the frame rate should be completely fixed.

I think you fixed it! Thanks so much for figuring this out, was dying to play this classic, the above explanation is the only one that sorts the screen lagging for me. Thanks again!
