Title: Darkened Screen
Post by: ChrisTom on July 22, 2011, 03:21:58 am: Hello. I enjoy playing Tremulous, but ever since I've been playing it on my new Computer, the screen goes to it's normal brightness, then gets to a very dark grey color. This makes it difficult to play Tremulous.

How can I remedy this problem?

My system specs are:

Windows 7 64 Bit

HP Pavillion

4 GB

Quad Core

Intel Integrated Graphics

Thank you for your time.

i have to do 3.5, but i must do it from xserver, the trem console command does not work for me.

i'm not on win7 anymore.

but I don't remember its range

r_mapOverBrightBits is defaulted at 2, I use 3, some people I know got to use 5. No idea of the upper limit.

No problem, lol.

Post by: vcxzet on July 23, 2011, 07:37:22 pm: 15 as the upper limit seems reasonable anything higher may cause overflow
( worst case (2^8-1)*(2^15)*(2^8-1)<2^31=int_max on most systems ; R_ColorShiftLightingBytes )
edit:
probably you won't see any difference after 8

I have this problem too with my Intel HD 3000 graphics on my HP Pavilion dv6tqe. The brightness bar doesn't do anything and neither does using the gamma command. But I don't care because I have a jacked up model with an AMD 6770, so I just use that. Here's what happens with the 6770: Starts up trem. Desktop gets really really bright. (normal) then it suddenly dims again and trem starts, extremely dark. r_gamma command doesn't work. I have to go into options every time I play and tweak the brightness bar before my gamma works. Not too big of a deal but seems interesting that only HP dv6t laptops do this...
