Many users complained about Need for speed 2 graphics distortion. One user tried to play that game and when race starts, graphics goes all bad and crappy. The reason is the graphics card or graphics software. One way to solve this problem is to use nGlide.
nGlide is a 3Dfx Voodoo Glide wrapper which ’emulates’ 3Dfx Glide Library, so you don’t need a 3Dfx Voodoo graphics card to play 3Dfx Glide API games.
All three API versions are supported, Glide 2.1 (glide.dll), Glide 2.4 (glide2x.dll) and Glide 3.0 (glide3x.dll). nGlide translates all Glide callings to Direct3D. Glide wrapper also supports high resolution modes.
