In order to play in glorious 1920x1080p, do the following steps: 1. Open your game folder (e.g. GOG Galaxy/Games/Rayman 2) 2. Run configuration tool "nglide_config.exe" 3. Set Screen Resolution to 1920x1080 4. Set Aspect Ratio to "Preserve Original" (optional, but IMO necessary due to lack of proper Widescreen support) 5. Set 3Dfx logo splash screen to Off (again optonal, for a faster start-up) And... that's it! Enjoy Rayman 2 as you should!
