I got a minor issue with ET (nothing big tough), i’ve updated and updated my video-card/sound-card drivers. But my graphics flicker and the sound dissapear ever now and then. Anyone who have the same issues as i have and knows how to deal with it?
Doom III is goona rock! 
What OS are you running? What videocard are you using? Did you install the drivers which were bundled with your videocard, or did you download the newest drivers from your chipset manufactorer ati/nvidia?
I don’t know about your sound problem… As chr0nicles said, that’s probably either something to do w/ OS, hardware, or drivers…
As for the gfx problem, one thing to consider is that some graphics cards and some specific graphics settings in your config file may not work together very well… So, what you could try doing is make backups of your config file, then download other people’s configs and try a few of them out and see if any fix the problem… Then from there figure out what’s different and fix yours. I dunno if that will work, but it’s a good option if all else fails.
chrOnicles: i’m using Win98 and a GeForce2 on one comp, and WinXP and GeForce4 on another. The drivers were downloaded.
velocity: ok thanks… the gfx problems is more annoying than trouble really. my chara’s mugshot and weapon animations dissapear ever now and then [especially on the fuel dump map wich even goes as far as “hide” some of my foes"]
