OpenGL/S3TC,4.7 Catalyst,gamma problems?

[SkaarjMaster]

Well, I finally upgraded my ATI drivers from 3.9 to 4.7 a month or two ago, but never tried UT again until now. I'm having gamma problems with the gamma being way too dark even though I have it set brighter within UT with OpenGL/S3TC and the latest Enhanced OpenGL driver from:

I haven't tried any registry hacks yet or anything from this Rage3D thread:

I just wanted to find out how everyone's doing with UT/OpenGL/gamma problems lately. Thanks for any help.

Here's my specs:

WinXP (SP1a)
P4 3.2GHz(Asus P4P800-Deluxe)
Thermalright SLK-947U
2GB Corsair XMS PC3200 Pro (and regular) RAM(4-512 sticks)
Sapphire ATI Radeon 9800Pro 256MB-AGP8X(4.7 catalyst,VGASilencer,DX9.0b)
SB Audigy2,Klipsch 5.1 speakers
Enermax 550W PS
Lian-Li PC-71 full tower case with window
Kenwood 72X CD-ROM,Lite-On 8X DVD burner
2-200GB 8MB cache WD HDs 7200rpm

If posting my OpenGL section of my UT.ini helps any, let me know and I'll do it. I just didn't want to do it just yet because of the space it takes up.

I think the 4.7 drivers don't respect a certain convention when it comes to OpenGL gamma. This has been fixed in later drivers (I think...) but I'm using the 4.9 drivers now and it's hopeless playing in OpenGL as animation is much too jerky. I'm using TNSe's D3D renderer until I can figure out a solution.

I may try that hack mentioned in the Rage3D thread then and see what happens. They also mention changing the multitextures setting to something, but I think I already have it set to True. I guess it's a good thing I stopped at the 4.7s for now. I really don't need that jerkiness of the animations. I could try the 4.8s, but I'll wait and see other comments first. I don't play UT very often, but I guess I'll use my other computer (Ti4400) if I want to play UT online, hehe.

It would be nice if they fixed this in the next non-CC drivers. Thanks for the quick reply.

Chris Dohnal (the one making the enhanced OpenGL render) got an ATI card since some time, after having used a Nvidia one, and on his website he wrote about several problem he ran into with several ATI drivers.

So maybe if you want to play in OpenGL with your ATI card, contacting him about it (and read the infos on his website) or about specific settings should be a good idea.

I always had the openGL gamma problem, but with the Enhanced OpenGL driver it was fixed.
What you can try too as an temp solution (what I always did) is too increase the gamma from you monitor in Windows.

- rightclick on desktop (monitor settings), settings, advanced and then Color correction.*
you will find the gamma under that.

* I think, I translated it from my dutch windows XP

All my other games are fine, so I don't want to change them, so I don't think I'll mess with the ATI Color thing for now. I've heard some people run into problems when they try to change this also. I may e-mail Chris though at some point if I try some stuff and nothing works.

Anyone know if turning off the VPU recovery solves this problem at all (just a thought)?

How are these new 5.X ATI drivers working for people in UT these days? I know it might be worth upgrading to the 5.4s for UT2004 and Doom3, but how about UT?

Did you try increasing the gamma offset in the .ini under OpenGL?

Nice bumb

And the new drivers work better with UT then the drivers from 1 year ago so you might want to give those a try. You may also want to try the enhanced OpenGL renderer for UT. It works a lot better then the default D3D and OpenGL renderers UT comes with.
