Unfortunately, I too am experiencing this issue. I am using the latest drivers from ATI as of this writing.
Windows XP Pro SP2 Until now almost everyone I know that uses ATI seems to have this issue
It is not limited to official drivers either, Omega 3.8.421 as well as Omega 3.8.270 caused this for me too Second Life 1.18.5 (73655) Nov 13 2007 12:57:54 (Second Life WindLight) CPU: AMD (Unknown model) (2010 MHz) Hi: Hope it helps... Second Life 1.18.5 (73655) Nov 13 2007 12:57:54 (Second Life WindLight) You are at 258793.5, 261498.9, 646.6 in Anilis located at sim832.agni.lindenlab.com (66.150.244.77:13006) CPU: Intel Pentium 4 (Unknown model) (3391 MHz) Disabling the "Catalyst AI" does indeed seem to fix the problem on my Radeon X800!
Yay ! Seem like the bug appears (for me) when Catalyst A.I. is set to Advanced.
Works fine with Standard. Does anyone have a fix for Omega Drivers v3.8.421 (Catalyst 7.10)? In the tray, I can select Catalyst A.I. to Off, Low or High.. nothing seems to make a change.
I was unable to get this to work with the latest Omega Drivers. So I entirely uninstalled them, installed the Catalyst 7.10 drivers, disabled Catalyst A.I. in the ATI Tray Menu et voila, everything looks fine now.
So Omega Drivers people, it just doesn't seem to work. Use the standard Catalyst drivers. If you can't, then beg the devs to fix this. Have fun! Yes, the Catalyst AI seems to be the issue.
I turned it off, and nothing changed, but I needed to restart WindLight, and it's wonderful now. Thank you to all those who found the answer. Gennifer Think you can add ATI RADEON XPRESS 200M Series to the list of cards with the Catalyst AI problem.
As soon as I put a check next to Basic Shaders box I get a crash. Unfortunalty I'm going to miss out on Windlight for now I'm using a Toshiba laptop so cant download Catalyst 7.10 from ATI to turn off AI and asChotaire says, nothing appears to change if you turn AiIoff in the Omega driver. Any ideas would be welocmed Second Life 1.18.5 (73655) Nov 13 2007 12:57:54 (Second Life WindLight) You are at 255835.1, 255667.1, 38.7 in Georgean located at sim2873.agni.lindenlab.com (64.129.43.115:13004) CPU: Intel Pentium M Series Processor (1592 MHz) After enjoying Windlight for a while, I found out that other Direct3D applications would blank my screen when using the standard Catalyst 7.10 drivers, leaving me no other option than a cold reset. This ofcourse is a driver issue not related to SecondLife, but It leaves me with the fact that for my X850XT I had to re-install the Omega Drivers thus breaking Windlight's color depth again. With other computers I am using, e.g. my Notebook running a OEM-modified Radeon 9600, my only option is the Omega drivers aswell, since the standard Catalyst drivers would not identify the card properly. So I rather abandon Windlight than the other Direct3D applications which I need to use.
Why I am writing this? I consider this Windlight issue CRITICAL due to the fact that not everybody has the ability to disable Catalyst AI as needed by this version of First Look. This serious bug is to be fixed so that Windlight will run in full color depth even with Catalyst AI set to advanced, and also when Omega Drivers (necessary for several chipsets and OEM-modified boards) are in use. Please do not release Windlight before this is fixed. I would also like to note that even when disabling Basic Shaders, performance is significantly worse than with the release version of the Second Light client. Thanks to each and everyone who chimed in on this; keep the feedback coming, we treasure it. I infact helped several Residents yesterday by telling them to turn OFF Catalyst A.I.. I'm not that familiar with ATI but Chotaire's note does concern me, so I'm importing this for closer inspection by Team WindLight.
Snippet from our office hour yesterday: [2007/11/15 13:20] Lillyann Chaplin: Quick note... the colorbanding is also present without the AI... on a x850 General advice
the x1950 pro and other ATI x1000 series seem to have many issues see link...
ATI's Catalyst AI has some problems with some specific edge case coding. There are some work-arounds that the end user can do, but they can cause other problems, esp. in other programs. The only real fix is to find the code that is triggering this edge case and fix it.
Work around #1: Turn AI off. (This does not seem to always work, and not everyone can turn it off) REPO: (On a working system, well after I actually tweaked Windlight to work, see
I'm having the above trouble and the suggested tweaks, re: disabling the Catalyst AI, do not seem to work. I've checked my card specifications and according to the details sent by the manufacturer it should support the level of Shaders used in the Windlight client up to Shader 3.0.
CPU: Intel Core Series Processor (1666 MHz) Graphics Card:Radeon X1900 Series
Another workaround is to turn off renderglow in client.....cant see the results of building your new glowy objects but if that's not top of your priority list then windlight works well. Client Menu / Debug Settings - type in renderglow and set to false
Yes, definitely Catalyst AI turned off solved on X1600 Mobile too
OK - X1950GT showed the same banding problems, which I fixed by changing OpenGL Texture Preference to High Quality. Having confirmed that it works, I reset my generic GFX prefs to Tecture Preference Performance, and set up an ATI Tray Tools profile for Windlight to turn HQ on when loading the program.
This works well for graphics quality in game, but breaks preferences. Running with the ATT profile and then opening preferences in the viewer will lead to the preferences window opening empty apart from the tabs at the side. Clicking any tab will immediately exit windlight and dump me back to the desktop. The workaround ATM is to load windlight without the ATT profile, change prefs from the login screen, then quit and restart using the ATT profile. It works, but is damn inconvenient. Using the latest (7.11) Catalyst drivers. As an aside, windlight seems to want to run in full screen mode regardless of the prefs setting. X850 Pro and 7.12 Catalyst drivers, disable Catalyst A.I. and the banding goies away. Thanks for posting this guys, I am now over the "WTF are they doing this looks like crap" reaction to WindLight.
CPU: AMD K7 (Unknown model) (2204 MHz) I just wanted to say, I have an x1300 Graphics card and I turn off the Catalyst A.I. off and all my problems are resolved with the banding. I look forward to the time when I dont have to turn this off. Keep up the good work. Windlight will really be awesome once it is completed! I keep missing the sessions hopefully I will be on one soon.
I have the same issue on my ATI Radeon X850 Platinum 256meg card.
CPU: AMD (Unknown model) (2408 MHz) However, None of the mentioned fixes for ATI settings work for me. No matter what, the only way to get rid of the banding is to turn off Renderglow as deedee mentioned. Hmm dont know if this a new thing or already covered.
WindLight First Look 1.18.6(75762 as previously mentioned if I set renderglow to false all tickety boo exept for glowing objects obviously scrap previous comment
Reloaded ati catalyst suite and driver....snapshots back to normal......weird Turning the Catalyst A.I. off also worked for me (Radeon X1300 Pro). WIndlight looks fine now!
Thanks yet again for your reports. We currently consider this issue a "Someday Maybe" (a status that exists internally but not on the public Issue Tracker), and here's a condensed version of what Brad Linden found after investigating:
Only after updating to the latest 7.12 drivers did this start happening to me.
I'm using an X800GTO, if it matters. Maybe rolling back your drivers would help. I was able to get my version of Windlight to look proper with my X800 running Omega 3.8.220 drivers by setting up a game profile under the ATI Tray Tools application. There are just two things you want to make sure of. Switch the OpenGL profile Texture Preference to High Quality, and disable the Catalyst A.I from the 'additional' tab to Off.
The solution is essentially the same, and since it's a game profile used only for this executable, the setting modifications don't affect your other applications as long as you set the option to "restore previous settings after game's end." I can post more detailed instructions for Omega Driver users if need be. The newest driver stack (the official ones) seem to have resolved this issue. I am now able to use the latest Windlight RC without setting a custom driver configuration profile. Perhaps it was fixed by Radeon?
