This game uses Direct3D Retained Mode as well as Direct3D Ramp Emulation for the 2D version. The 3D version works more or less the same with or without dgVoodoo2. The 2D version has issues, in Windows 10/11, the mission render is incomplete and it only renders the sky. dgVoodoo2 fixes it and the game renders quite fine.
Now the problem I faced can be traced from some specific points: Mission - Tunnel Race Level 1. Here, I find that the tree in 2D version has a white outlining for some reason. When you ride the scooter and reach the tunnel (which is white from outside), you will see that the tunnel is white inside in colour.
Now the comparison starts from Windows 98 and Windows 7. Both of them can play the game without dgVoodoo2. On both OS, the tunnel inside is opaque blue and the tree near the start line has no white outlining, something which doesn't match dgVoodoo2.
DxWnd is also trying to emulate the same on the RGB device instead (and has been quite successful except the tunnel is transparent glass now), so a discovery on how the game should look can help both softwares.
