What mechanism are you using to sync to vertical retrace?
Also, the for loop you provide is not going to be very fast code
for copying the buffer, at least not in my experiences. Try using
something like memcpy() for the bulk of the copying, perhaps a memcpy()
invocation per horizontal line.

If you want tearless rendering you should be flipping. Ie. render
to a non displayed portion of the framebuffer, then call XDGASetViewport
to display it after the copy is finished. See the DGA test apps at
http://www.xfree86.org/~mvojkovi/, specifically texture.tar.gz.
If the texture and

Isn't DGA mode being phased out? I been using XPutImage and the XVidMode
extension to provide fullscreen instead. Only problem being you have no control
over when the image is actually copied to the display, so tearing results,
unless someone else here would like to enlighten me...

Hi all,
Looking at the xfree86 source of nv, it seems that the maximum resolution
achieved when the input type is DDI is set by the BIOS (fpWidth/fpHeight).
Is there a way to bypass this limitation such as a flatpanel display capable
of 1600x1200, but only 1024x768 is achievable. IOW, what

The nv driver contains no code to program the DVI interface. The
only reason why it works at all with DVI is because the BIOS setup
the timings for the text mode. Subsequently, the nv driver is not
able to run in any mode other than the one the BIOS setup. If the
BIOS setup the text mode to
