This could be either a bilinear magnification filter or more likely your
trilinear MIP map minification interpolation. I expect if you have a 1 pixel to
1 texel ratio on a 'sprite' you'll be interpolating between the level 0 & level
1 MIP textures. The simplest solution is to select a point sampled or bilinear
minification filter and see if things improve, experiment to see what gives you
the quality you need (I expect bilinear is what you want, it depends on what
youre doing). You could also be seeing some colour quantizing due to internal
format bit loss so also try an internal format of RGB8 but bear in mind there
may be some performance related issues.
Rgds,
Angus.
