In my main retro PC, I use an ATi Rage 128 32 MB AGP card, as the original TNT2 M64 didn't want to get detected by any of the games I wanted to play. 😕 😕 Unfortunately, the card has some weird visual issues in 3D games, but is fine in Windows. For example, in ReVolt, this happens.

In Sega Rally Championship, things get even more messed up;

Any ideas as for what could be causing this?
