Gamma and DarkPlaces / FitzQuake / Enhanced GL

[Baker]

Just wondering if I have terrible luck or what?

I have never been able to adjust gamma in-game with DarkPlaces, FitzQuake or Enhanced GLQuake. I can adjust brightness (gives a faded look). All of those engines use the same code for that, as far as I can tell.

On the other hand, JoeQuake/Qrack/FuhQuake/FTEQW/EZQuake all can adjust gamma perfectly with my desktop's GeForce2.

A laptop I have works fine with Enhanced GLQuake's in-game brightness controls but the Radeon 9500 (or whatever it uses) doesn't seem to like DarkPlaces at all and it won't run.

Just wondering, it is a little frustrating to me because I'm working on something for DarkPlaces that I can't actually get the full benefit of (being totally unable to set the gamma is very frustrating) but I am hoping this problem is limited to my card --- which I do not expect many people are using.

I've a GeForce3 Ti200 and I've no problems with hardware gamma in any of those engines except that DP uses cvar v_gamma and most others gamma. It might be a driver issue. In my GL-engines you can also set via option "-gamma x", but that usually produces a washed out brightness.

Is there a difference between fullscreen/window and what gamma value are you trying to set? Too high or low values are usually not accepted from the driver.

I use the -gamma parameter with your engine and everything works fine (the in-game one has the same issue).

I am just trying to use the standard gamma slider bar in DarkPlaces, it is really difficult for me to determine what textures and other graphics look like "in-game" without being able to set the gamma. It doesn't work in DarkPlaces in either -- windowed or full screen. I'm trying to set a gamma value of around 2 (well within the usual range).

I updated drivers (what a disaster!) tonight to see if it fixes the problem and it didn't and now I get 17 FPS after the driver update, hehe.

I think I'm going to get a new video card, if it's only me -- I never see anyone else talk about this.

I discovered I can set this manually in my video card settings in the mean time, which will allow me to use what I imagine are the typical settings so I can see how things look together.

Ive never had to adjust gamma in a Quake engine before honestly.

Me thinks scar3crow is telling the "tall tales" again.

"Always won with 800 ping", "Almost beats Monster", "Plays multiplayer with DarkPlaces real-time world lightning on", "Beat single player his first try without dying", "Has played Quake since 1995" ... hmmm

Should we believe him this time, hehe?

Just note that if you use the "-gamma x" option, the in-game gamma adjustments won't work. If possible, it's better not to use that option.

In Darkplaces, you can go into the COLOUR submenu and increase the gamma in game. I usually make it too. But still, the dark areas will still be dark and the bright places make the other players pure white.

I'll check this out on my laptop, which can run Enhanced GLQuake just fine.

I'd prefer to use the in-game adjustment, the command line option does look washed out a little (I guess I'm used to it).

Baker - I also didnt have trouble seeing in Doom3 for the most part, from what I can tell my monitor is brighter than most - hence Ive not had to adjust the gamma in any sourceport - I did for the original Quake, but that was back when I was in highschool and thus playing on the family machine.

"Plays multiplayer with DarkPlaces real-time world lightning on"

I only do that sometimes... LordHavoc and Willis (of the Transfusion project) do so in 1600x1200 with 4x AA and all that jazz - and get better framerates than I do in non-realtime.
