[Dri-devel] very slow glTexSubImage2D()

[Arpi <ar...@ba...>]

Hi,

Is it possible that glTexSubImage2D() in Utah_GLX is _much_ faster than
in DRI?

I'm using it in my mpeg/avi player to allow hardware-accelerated
scaling. It works well with Utah-GLX, but it's very slow (eats too
many cpu) with DRI.
I'm updating same texture in Nx16 pixel areas, where N is the texture width.
When all the areas are updated, I'm using glBegin(GL_QUADS)... to draw it.
