Hi,
I have a strange problem with the NVidia drivers on my machines: when I start
a glx-application (glxgears, quake2...) the performance is normal. If I
make another attempt a few minutes later, the performance is ridiculous slow.
Example:
glxgears, 1st run: 6400 FPS
glxgears, 2nd run: 17 FPS
FreeBSD-versions: 5.2.1-p9 and 4.10-STABLE
Nvidia-cards: GF4-Ti/4200
Boards: Asus A7V-600 (Athlon XP)
Same problem here on FreeBSD 5.2 (recent -current), I have the same
nvidia card with an Asus A7M-266 board (AMD chipset). I haven't observed
it on 4.10 (yet?).
If have tried several combinations of AGP-Support (FreeBSD vs. NVidia),
nvidia-sysctls, XF86Configs ... without success.
The next strange thing: if I wait several minutes, the performance
is normal again, but only for 1 attempt, the next one ist slow again. This
makes playing Quake2 impossible, because connecting a server includes a
vid_restart (- slw).
Yes, looks familiar. I'm playing UT2004 and often it starts very slowly.
A workaround that sometimes works for me: I switch to console (ctrl-alt-F1),
and wait until I hear from the sound that the main menu is displayed.
Switching back and voila, it's back to normal. At least, most of the time :-P.
(Usually, doing this sort of things is asking for trouble.)
I guess that something gets locked somehow. The next thing I want to
try is an older 4.x version.
Could this be a problem with the VIA KT600 chipset? Does anybody
else experience this problem or am I the only lamer playing Quake on
FreeBSD? ;)
You're not the only one... different chipset, different game but looks
like the same problem.
Karel.
