Graphics performance is better of what it seemed could be archieved at the 
beggining, but Glamo's bus slowness is not something "someone said", it's a 
Also, qtopia (qtextended, qtmoko) do a lot less effects on graphics than 
enlightment, that's why it's faster.
If you turn off shadows, transparency, etc, you can get shr graphics as fast as 
If you don't believe me, you can try SHR's Neo Theme. You will see it's not X, 
but eyecandy what makes SHR slower than qtopia.

You can search lists archives for several threads about this matter, it was 
spoken to death.

No, it can't, at least until we have an OpenGL driver. But it's true that using 
VGA resolution is a handicap for such a slow graphics chip, and it would be 
better QVGA for this hardware.

Fact is that glamo is a graphics "decelerator". It's known that Neo1973 was 
faster than FreeRunner on graphics (even on VGA), despite of slower processor.
