Yeah, but the solution is to subdivide the map further. The PS1 had that feature in the sdk from day one. The Saturn, as usual, doesn't and can't really do it. I'm trying to find a way to clip textures in vram to subdivide it in 4, but I'm not sure it will work.
These days I was watching what you told me that the SCU-DSP would not be useful for real time tesselation. Looking at the PSX SDK, it seems that it uses the GTE for it, but I'm not sure that it's for everything. I mean, I think for tessellation. The GTE is used to recalculate the UV coordinates of the new polygon or polygons. But I think that to divide it uses the CPU. In a technical document a developer asks which is better to divide the GTE or the CPU and they respond to the CPU. Which we can apply to the SS because the SCU-DSP and the GTE are very similar doing addition and multiplication to dot product mainly. And the SH2 has divison instruction. Unless divisions can be made with multiplications of decimal numbers in the GTE and in SCU-DSP?
