Package: gliv
Version: 1.9.1-1
Severity: normal
gliv seems to always use 128x128 textures. This unfortunately makes
rendering slow on certain systems (such as a Radeon 9000 chip or a $99
GeForce). The large # of small texture tiles seems to bog down the
card.
There is code in gliv's src/gl_widget.c to query OpenGL for the maximum
texture size, but this is commented out by a preprocesor directive and
is replaced by code to default the texture size to 128x128.
If I reenable to maximum texture detection, gliv runs much better on the
above mentioned graphics cards (performance jumps from approx. 1 frame
per second to undetectably fast).
The following patch reenables maximum texture detection:

My worry is that the preprocessor directive must have been put in for a
good reason (and it has been present in gliv for quite a few revisions),
and there must be some important cases in which using the maximum
texture size is unacceptable. I would hate to advocate breaking gliv
for others in order to fix it for me.
