Hi all.
Grass 57 is running much faster on one Mandrake 9.2 (PentiumIII/450MHz) than
on several Debian boxes (k7/>1700MHz). This is especially apparent when
digitizing (screen refresh of background raster maps takes much longer). Has
anybody encountered this? Any ideas about possible reasons/solutions?
All the best.

It's probably due to DRI acceleration often not being turned on by
default in Debian's X. Probably depends on your video card/setup.

direct rendering: No
Except for NVIZ, DRI won't make any difference, as it is only used for
OpenGL, not for the core X operations which XDRIVER uses.
