Video Card

Post by **corpse** » Mon Jun 12, 2006 7:01 am

I have a Radeon 9800 Pro with 128Ram and lately when I play Quake3 the screen goes dark after a few minutes of play. When I quit Quake and go back to my normal desktop everything is bright and fine.

Is this a Quake thing, or is my video card dying?

does it stay dark?

have you tryed playing with the gamma?
or putting Hwgamma to 1?

do you have anything running in the background wile you are playing? ( Note: This happened to me wile i was playing and something like MSN was open in the background. )

NOthing is running in the background and yes it does stay dark.

Havent tried changing any setting, but they are the same settings I used to use and this never happened.

hwgamma to 1.......where do I find/change that setting?

Press tilde while in the game to bring up the console and enter the command there.

r_ignorehwgamma 1

my 9800 is set to
r_ignorehwgamma 0

also, when it go's dark Change your gamma settings "R_Gamma" even if you change it by a decimal point.. it will brighten up.

and scan for spyware/malware on your computer.

I tried changing to r_ignorehwgamma 0 but it still goes dark after a few minutes.

While in game, do I press the tilde key and then do

r_gamma 2.......................or whatever. I tried that and nothing happened.

press ~ ( titdle key )
then type r_Gamma
then enter
Read what the value is, then Up it up .1 or somthing.

it should brighten up.

Make sure you put in this exactly: r_ignorehwgamma 1

The fact you even said 2 makes me wonder if you input the command correctly.

Actually I put in r_ignorehwgamma 0 because Axbaby said his 9800 is set to that.

The '2' I mentioned was put in the r_gamma.....just playing around to see if things would brighten or darken while ingame.

I will change the r_ignorehwgamma from 0 to 1 and see if that helps.

No, changing it to r_ignorehwgamma 1 does not help. Still goes half-way dark after a couple of minutes.

I seem to recall a command something like overbrightbits or something......could this be it?

just delete q3config.cfg and let quake make a new one.

my screen the odd time will turn white when a windows task completes or an alert pops up like Amidy said earlier.

have you tried different video card drivers yet?

Post by **corpse** » Tue Jun 13, 2006 5:51 pm

Yes, I deleted the old ones and then installed the latest cat 6.5

I remember that my screen used to go white [kind of washed out looking] once in a while.....maybe that was what the r_overbrgihtbits thing was for

ax! you have your refreshrate at 100hz?!

Post by **axbaby** » Tue Jun 13, 2006 6:44 pm

yar

the highest my monitor can do

Post by **AmIdYfReAk** » Tue Jun 13, 2006 6:46 pm

corpse, check what your monitor can do before you use that "r_display refresh" command!

Post by **axbaby** » Tue Jun 13, 2006 7:18 pm

good idea

Post by **corpse** » Tue Jun 13, 2006 7:26 pm

I have a new acer LCD. My resolution is set to 1360x768.

Within Quake my resolution is set to 1024x768

Strange thing here...maybe

seta r_ignorehwgamma "0" was in my q3config, but within the game and the tilde key I changed it to 1.

Anyway, I changed it manually in my q3config to 1 and now when I start the game, it is dark right from the start.
