I didn't know where to post it since it actually works with all classic westwood games (td, ra, ts, ra2, dune 2000).
DDrawCompat is a DirectDraw proxy dll just like cnc-ddraw, ts-ddraw, ddwrapper. It improved the performance dramatically for everyone who tested it yet (went over 14000 FPS in ra1 for me!!). It also solves the alt+tab bugs on windows 8/10 (and the menu bugs too).
It should work fine on Vista, 7, 8, 8.1, 10. (We had no one to try Vista yet)
Even if you don't have any issues with the games, it's still worth a try. It prevents slow downs in big battles online or even in skirmish with AI.
Give it a try:
Note: use the latest experimental release
You should be able to start YR with a "-mpdebug" parameter to be able to see the FPS
