Both Carmageddon 2 and Ignition are as known compatible with the Glide API (Carmageddon 2 also has Direct3D support, but in my experience it doesn't run as well with dgVoodoo2), thereby they are excellent candidates to dgVoodoo2 and its Glide wrapper.

Using version 2.55.4 of dgVoodoo2 makes the experience running those games in 3dfx mode with forced resolution a more or less perfect experience in my humble opinion. Using the newer versions of dgVoodoo2 however, thereby the 2.62 version, there are some things with the graphics that seems broken in the 3dfx mode. In Ignition the yellow graphic effect for when the nitro/turbo bar refills seems to be missing in 2.62.1, yet it's fully displayed in 2.55.4. In Carmageddon 2 much of the graphics in the main menu seems to be missing in both dgVoodoo2 2.62.1 & 2.62.3, while it's fully displayed in 2.55.4 (all tests done in the 3dfx mode in the game).
