I've no influence on the result of trilinear filtering.
Ah ok. Might just leave that option then.
For the S2 it should have the highest of settings on.
I can count the colours on that texture... 7 heh.
I did have glDither on but not before the FrameBuffer. It does help.
Found that replacing:
aa = new AAConfigChooser(mGLView, true);
with:
aa = new AAConfigChooser(mGLView, false);
Improves it a little more. But still really looks 8bit.
