It would hard be to overstate the utility for retro gamers of a visual feature list for games, accompanied by a hardware list of visual capabilities for applicable APIs.
- a single 16 gray texel scaled up and modulated up, to expose filter precision
- a basic room with colored mip levels to show the standard lod calculation and bias
- some really additive-blended overdraw of a dark texel to bring out the 16-bit color dithering matrix
- Some 1x1, 2x2, 4x4, 8x8 and 16x16 textures for testing the minimum texture sizes allowed
- Some rectangle texture tests to see if those are allowed
- Texture clamping modes
- a reminder that no 3d card is perfect in any of these results and they are purely subjective tastes
Some of those are a deep dive for me. I'd rather start with whether a given card can run 3D feature X in game X with official drivers and no tweaking. I'd be after objective results. E.g., the Matrox Mystique cannot do bilinear texture filtering for any game or API.
It may be helpful to identify, if at all possible, the 3D features developers considered ideal. So, while someone may prefer the look of emulated table fog to actual table fog, the fact that it's trying to be something else shows that something else is ideal.
