Hi! I bought Rayman 2 when it was released in GOG, and since then, nobody resolved these little issues:

DirectX mode issues:

1- The game runs in 16-bit color mode.
2- The game's framerate drops from 60 FPS to 30 FPS frequently.

Glide mode issues (using nGlide):

1- The game runs at constant 30 FPS (even if it is displayed in 32-bit color mode).

I tried modifying the "ubi.ini" file but no luck.

Anyone knows how to solve these problems? The game runs fine, but not perfectly!

Thanks!

I believe the game runs at 30fps simply because it was coded to that frame rate. As far as I know, there were no 60fps games at that time (1999). It's an old game so you probably won't get the highest quality available.
