Added 2020-02-21 18:23:23 +0000 UTC
One of the final pieces of the puzzle regarding Dreamcast mipmapping was finally solved! Dreamcast had a feature called βMipmap D-Adjustβ which in practice is nearly identical to mipmap LOD bias, with the only difference being that it works with a factor (* d-adjust) instead of a bias (+ lod bias).
Flyinghead came up with the implementation, it has been merged and should be in the nightlies later today.
We made two comparisons here β one with Daytona USA 2001, the other with V-Rally 2 β
