A question about 10.5....can I use 10.5 drivers and 10.8a profiles together without conflicts?
Yes. That's the point of splitting up the application profiles from the drivers, so you can mix and match.

A question about 10.5....can I use 10.5 drivers and 10.8a profiles together without conflicts?
...and the scaling issue wasn't fixed.
Thanks for the response Terry. I think the main issues in this thread are:
***4xxx X2 series with the second gpu not clocking or working properly.
***Hotfix on the way.
***10.8a BFBC2 crossfire 5870 or 5850 (2 cards 1 monitor), users experiencing low FPS, approximately half of 10.5a. Frames actually increase turning crossfire off.
***Open issue.
***Users with HDTV via HDMI: reporting over scan not remembering settings and color saturation slider not functioning properly with crossfire.
***Open issue.
***Crossfire scaling including quadfire. Nvidia has seen strong improvements in SLI over the last few releases.
***Open issue.
I am in the process of re-reading this thread and filtering through all the troll comments. I will update this post with issues that have been reported by more than 2 users on this thread. Hopefully that will help the team that is looking at this. I am sure that most of us, my self included, would be willing to give more details or clarification. So just ask.

4) I need to see specific numbers/games where it is percieved that scaling is not good, or nvidia has better scaling than us, in order to reproduce it and fix it. Note - Quadfire scaling was improved in last months hotfix http://support.amd.com/us/kbarticles/Pages/ATICat107aBetaDriver.aspx
Dual monitors enabled any games causes dropped frames / framerate dropping issues whenever I move my mouse.
2) BC2 details (5850 Crossfire)
Happy to add in details:
My specs:
Motherboard: Asus P5Q Deluxe
RAM: 4gb Corsair Dominator
GPU: 2 x Asus HD5850 (not overclocked)
CPU: Q6600 @ 3.2ghz
OS: Windows 7 64 bit
Resolution: 1920x1080
CCC settings: Default (I have played around with AI but didn't make any difference).
Game settings: Everything on highest except HBAO = OFF and SHADOWS = LOW. BLOOM might be off (need to check) and I think I use DX10 (though have messed around with the DX version via the config and it didn't make any difference anyway).
How I test my FPS:
1. Start FRAPS
2. Start BC2
3. Load up an empty ARICA HARBOUR map
4. Start game and make my way to the zebra crossing at one end of the main street, where I stand and point my crosshair at the flag on top of the flag pole in the middle of the street.
5. Make note of FRAPS figure
10.5a
Result = 80 fps
10.6 - 10.8
Result = 35 fps
If I turn CAT AI = OFF and use 1 GPU under these drivers the frame rate I get is 50 fps
Weird as heck. And no matter how many times I uninstall / re-install versions of drivers, the result is always the same.
I am experiencing the same issue. When I start up World of Warcraft for example the FPS drops to 0 every time I move my mouse and everything is very choppy. If I disable Hardware Cursor then the problem goes away but without the hardware cursor my mouse isn't nearly as responsive which is a deal breaker.
specs in sig.
I mentioned these earlier but they may have been missed:
1. The CrossFireX issue with Prince of Persia: The Forgotten Sands is still there in 10.8 + 10.8a CAP. When the prince dies and you start from the last checkpoint the framerate drops to 20 fps and stays there. Alt-Tabbing out of the game then back fixes it. Disabling CrossFireX is a more permanent fix but I'd rather see CrossFireX supported properly. It's what I bought the second card for after all!
2. Blur doesn't support CrossFireX at all. I believe ATI disabled it because of a bug with CrossFireX that caused the framerate to drop to 20 fps when driving through water and it stays there until you restart/reload the race. This is a similar issue to the Prince of Persia one.
Renaming the Blur executable to DiRT2_Game.exe allows the game to run on two GPUs with a better framerate, albeit it feels oddly laggy, so why isn't it properly implemented yet? I don't get a solid 60 fps with one GPU either and it annoys me to see my second GPU just sitting there doing nothing. The game has also always been stuttery on my system, especially during the pre-race fly-by, but I can't be certain whether this is a driver issue or something specific to my system.
3. Red Faction Guerrilla has some serious framerate dips with CrossFireX in areas where there is lots of vegetation/foliage but otherwise runs fine in the more desolate Martian areas. I know this is a comparatively old game now but I still enjoy playing it.
4. BioShock 2 doesn't support CrossFireX which would be useful when forcing anti-aliasing (at least in DX9 mode). Incidentally, why is it that NVIDIA support AA in DX10 in both BioShock and BioShock 2 but ATI don't?
This is good - thanks! Please can you just confirm that with the hotfix from yesterday 10.8b that you stil get 35 FPS on the above map
Brand/Model: XFX 5870 XXX
Driver Set: 10.8.
System:
- I7 940 Stock.
- Asus P6T Motherboard.
- 12 gigs Corsair RAM @ 1333MHz
- Corsair 1000 Watt PSU.
- Windows 7 Ultimate.
Problem: OpenGL support is still broken. If I start up any OpenGL game with a driver set passed 10.4, it crashes. I am at work now, but will take a SS of the error when I get home.
Another oddity I've noticed with the 10.7 and 10.8 drivers... DXDiag shows the Approx. Total Memory available as 716 MB for my HD 5870 rather than the expected 1,024 MB. Other third-party tools show either 1,024 MB for the card or several GB (which presumably includes some system RAM?). Is this a bug because I'm pretty sure it showed more memory with the pre-10.7 drivers?
My concern is that if DXDiag only sees 716 MB then games may too which in turn could limit the settings I can use or even introduce issues such as stuttering because the game is paging data to and from system RAM because it sees less free video RAM.
Do you have v-sync enabled by any chance?
I ask because I downloaded the Amnesia: The Dark Descent demo a couple of days ago, a game which uses OpenGL, and it will only run so long as I don't enable v-sync in the options. If I enable v-sync in the game, it attempts to restart but never loads, instead it crashes to the desktop every time. The same happens even if I manually edit the config file to enable v-sync.
Now I've not tried any other OpenGL games such as Doom 3 or Quake 4 yet, both of which I have installed with v-sync on, so it may be an issue specific to that game. If I remember I'll try them later to see if I get crashes with those.
To be honest, I'm not impressed at all with ATI's OpenGL drivers as it seems very buggy compared with the ones I was used to from NVIDIA's drivers. I tried playing Doom 3 a month or so back only to find out the HUD was all weird and the textures/shadows flickered. I fixed it by using the OpenGL file from the 10.4 drivers and placed in the same folder as the Doom 3 executable. That fixed the issue for me but it really shouldn't be necessary. OpenGL is rarely used in games these days so it's disconcerting when the few games that do use it don't even run properly.
Happy to help. Am currently on 10.5a with 10.8 CAPS. Went in and verified FPS as posted above and saw exactly 80 FPS with Crossfire enabled.
Grabbed the 10.8b hotfix and just installed it over the top of 10.5a, frame rate was just over 40 FPS with Crossfire enabled (and the Crossfire logo was displaying on the top right of the screen).
Now here's the weird part. I turned CAT AI = OFF and went into BC2 again and my FPS was 85. Crossfire logo was not displayed.
Now I'm really puzzled
forgive my ignorance but what does one need to run AA in SC2? Is it just 10.8a drivers? or do I need a patch on top of it.
I have been following this thread for about a week now and have decided to post.
Here are my system specs:
Asus M3A32-MVP
8GB Corsair Dominator @ 1066
Phenom II X4 965 (125w) @ 4.0Ghz
2 x Asus 3870X2 in Crossfire X (old I know, but still pwns)
Windows 7 64bit
I have tried everything except the 10.8b driver (since I just saw the hotfix just this morning). Nothing past the 10.4a driver works worth a crap for me in BFBC2. With the 10.4a drivers I have 3 second loads and am seeing about 90fps average at 1680x1050 everything full on and turned up except I don't run any AA. With anything above 10.4a I get C2D all the time, long load times (way over 30 seconds) and corrupted textures (appearing as big areas of black). I also see texture flashing and never get above a max of 50fps. I will give the 10.8b's a try tonight and see what happens. I thought I would say something since nobody has said anything about the 3000 series...
