The texture limit appears to be already smashed. I can load MIPs (~122 MB) with a vertical resolution of ~16384, by replicating the texture vertically. The horizontal resolution has limits,
Rendition hardware supported horizonal resolutions of around 2048 in Windows (RRedline), but the limit may be lower in DOS. I'll dig up a list of valid horizontal resolutions. The vertical resolution can't be scaled higher than 16384 because modern OpenGL hardware doesn't support textures bigger than 16384x16384, the wrapper wouldn't be able to handle it. Original Rendition hardware doesn't have vertical limits, other than memory.

Using this build of Dosbox-Rendition which supports 1.5 GB of RAM:

and these patched version of ICR2 (1200 MB) texture buffer:

For good measure this version of Denver with 16384 textures (43MB) can be loaded along with the carset. Performance is horrible, but it loads:

So tracks with higher resolution textures should be possible, but there's a limit to how many total MIP map levels can be loaded. That looks to be my next task.
