OpenGL and GeForce Problems

I have this exact problem, except it also occurs in DirectX. Turning off 'GL Extensions' in-game for those that are based on the Quake 3 engine seems to delay the problem, and turning off 'Enable Write Caching' also delays it, but it still occurs. Hard lockup with horizontal and vertical lines and looped sound after a random amount of play. I actually E-mailed Leadtek about this (I have a Leadtek WinFast GeForce 2 Pro 64MB-5.5ns DDR) and they just gave me an RMA form.

I hope it is not an AGP bus speed issue, because my motherboard only works at 4x.

I have the newest BIOS for my motherboard, newest reference nVidia drivers (29.42 as of writing), newest Intel chipset drivers, etc.

Another one with similar problems, using :
Asus V8170 GeForce4 64mb DDR / ECS K7S5A / AMD 1400mhz on WinXP Pro. Latest everything.
I'm not a big gamer, so i only had this on the one game i play - Unreal Tourn GOTY edition.. Can be anything from first map to 10 maps into the game [always LAN games] and i get a hard freeze, reboot required. Noticed also that during this freeze it's not just the video subsystem frozen, the box cannot even be ping'd over the network, no traffic leaves the box at all [can see on the switch]. Audio seems to die just before the freeze, like quarter of a second before, a sort of crack sound from the speakers.. And again nothing in the event logs or the game logs, the game log actually stops "mid word"..!

Just thought I would chime in. G4 Ti 4600 Amd 1.33

Same problem as every one else.

Firstly, your fundamental problem lies in not the software, but the HARDware. Your processor does not support the machine code generated by Quake, Halflife, or Unreal Tournament, as well as varied cd-ROm male pornography. I suggest you ass-fist a yellow tailed monkey, while shouting and gesturing obscene and sexually charged things at your grandmother.
Secondly, find a girl, bitch. Get a ****ing life. Eat ****.

I'm staring to think that The G4 seris is a big piece of $hit. I'm having the same problems too but I have talked with everyone the maker of the card and maker of 3 different games and mircosoft too

I have the same prob with UT (but not JK2 or Renegade), those have a different problem (see post Graphics Glitches).
UT just freezes when i go to run it in opengl mode.

Okay I used to have that problem with two
different mobos an old FIC 503a and my current one, an ABIT kt7a. Both have VIA chipsets.

The tweak of slowing down your AGP card speed
from 2x or 4x to 1x worked in both cases when OpenGl games crashed. Installing the via driver and selecting the standard mode ( NOT turbo) worked. Also going into the BIOS and slowing down your AGP speed helped. Both times I had Win98se in my rigs. Since then I have upgraded to XP pro and all seem to be working fine. I have all the newest "official" updates from mobo BIOS to via chipsets.

My sys specs:
Abit kt7a ver 1.2
256mb ram
900mhz t-bird
Abit Siluro GeForce3 ti200 64mb
Snd Blstr Live value
pci modem
DVD decoder card
firewire card
cdrw, dvd, 40gb WD hd
winXP pro (with all the patches they post every other bloody day!)

I'm not using Nvidia ref drivers, but the Abit ones. ALL my openGL games work and I have the AGP at 4x. Via drivers all enabled, no slowing down agp drivers junk.

Try this forum I found some clues there way back when...

Lots of discussions on all subjects.
What have you tried lately? Have you fixed your problem yet? Sorry I can't be of more help but know that not all of us have problems with VIA and OpenGl.

Live well,
