It's a pretty neat resource, but AFAIK it has a few (probably minor)
1) The data-set changes over time. This might not be a real-world
problem, as measurements are presumably taken with two identical
2) It contains a *lot* of basically the same thing; raymarched
raytracers. So I worry a bit that pulling in all of the
Shadertoy-shaders ends up punishing "normal" shaders, by making them
seem more fringe. The raymarchers on Shadertoy tends to be extremely
ALU heavy compared to games shaders, and do very long loops. I have no
doubt it's healthy to have *some* such shaders in shader-db, but
perhaps all is overkill?
3) Since all use the same vertex shader, won't changes to that get
artificially high scores?
I'm not saying these are showstoppers, just something that might need
