HD 7xxx drivers for flicker/BSOD fix

[alexey_detr]

Some another details about this annoying flickering problem.
Playing Witcher 2 today and noted that latest Catalyst 13.3 beta 3 driver cause flickering every time when I'm playing with ultra settings. Can anyone confirm that?
I've reverted to 13.1 and there is no flickering now. But in another thread on this forum already talked about that version 13.1 is the cause of flickering in Firefox under heavy load.
Oh, so many problems with new video card. That's really disappointing me. I'm going to RMA it if next version of drivers will not fix issues.

Thats strange. 13.1 doesn't contain the flickering fix. 13.2/13.3 does. May be a different flickering?

Probably you're right... All this situation looks like AMD making too aggresive optimization of their drivers. I've heard that they are optimizing a lot for certain games via tuning visual quality (e.g. cut not important graphical details) in these games to achieve maximum FPS. May be this is the reason of artifacts and glitches. That's just my thoughts about current situation, I'm not sure if it's so actually.

Furthermore I've made a many stress tests of my GPU with errors checking and they all telling that graphical system is ok.

Simply get close to any wall, and rotate camera in a manner when body of your character becomes transparent. it will start to flicker like this:

I keep old not updated version of skyrim to re-test all I can.

to alexey_detr:

I have been testing Witcher 2 for long time. The game contain flickering which is related only to game engine, not to the graphics card. I have tested it with both Nvidia and AMD...

the flicker you see in Wacraft 2 is quite strange, but its not DX9 flickering. Also keep in mind that 13.3 Betas dont use CAPS, they have them already installed inside the driver. So if you forget to uninstall previous drivers or caps it may result in bugs you see.

Oh that one? But thats not the DX9 flickering imho. As long as you can reproduce it it's mostly smth different in my opinion. The Dx9 flickering was never reproducable for me. It appeared random, on some places more frequently on some less frequently.
The only game with some rare artifacts i play is starcraft 2. Sometimes is see strange lines for a moment there's also a picture of that issue somewhere in the forums. Guess most people wont notice that.

its visible only on HD 7000 series. When I tested any other graphics it was gone...

I can say only that its related to HD 7000 series, while it was always visible regardless driver. I have not tested different game version.

Its certain that while skin is becoming transparent it will become completely transparent instead of partially. According to my knowledge this feature is directly related to DirectX...

Previous known issues with DX9 flickering was mostly triggered on waterfalls. There is done a lot of transparency effects. This is transparency again. As you notice not each texture is affected. Affected and unaffected textures switch over time in apparently random manner.

Thats all I know about it, and I can see similarities...

I believe that all those issues have something to do with "transparency level" and alpha channels. shader sometimes returns 255,255,255 or 0,0,0 instead of correct value...

Would this issue be reproducible under Linux + fglrx + Wine?

[erocker]

I get a very occasional 2d flicker. Happens in Windows 7 and windows 8. Linux? No, doesn't happen. Almost positive this is driver related... It's just not that big of an issue where I feel like trying different drivers to correct it. Aside from the occasional flicker these latest beta's have been outstanding.

I dont know, but its worth a try to test it.

Its just only my opinion that the best testing has to be done on native game, DX and driver environment. Wine however does not comply to this...

short test (GTA4, DOTA2) confirmed that official catalyst 13.4 seems to be first WHQL with no flickering

[NiColaoS]

Lol... These corruptions came to BF3... A guy on OC.net mentioned black artifacts and I just saw them. These artifacts are flashing extremely fast...

Offler2, do you play BF3 in order to confirm if you can? Personally I know what I saw, but for other people here.

I'm on 13.4 currently.

I use this, though: WorldRender.DxDeferredCsPatchEnable 0 -which I think it disables something Dx11-related. Now I turned it on to check again whether the flashing continues to occur...

[Offler2]

I dont play BF3. And i refused to buy games for sole purpose of gpu testing

Sorry I cant confirm this.

to the topic:

Skyrim:
Black flickerspot: Clear
white Flickerspot: Clear
Transparent skin flickering: Still present

Witcher 2:
Flotsam forest: Clear

Not DX9 related flicker:

Starcraft II "newkirk" bug:
Still reproducable from the replay...

I believe that majority of DX9 flickering is solved with latest WHQL. I have to re-test a bunch of games old and new. The transparency trouble in skyrim are the last trouble I still can reproduce.

AMD is currently moving to different problem - crossfire and stuttering. performance-wise its more important for now.
