Ati Catalyst 8.12 hotfix (for multi cores)

They should at least give an example of the supposed speed increase.

And shouldn't we be hearing something about the 9.1 drivers by now?
 
I hope 9.1 delivers a major performance boost, else I may have to jump ship.
 
I assume you were testing at lower settings where a game is more likely to be bound by the CPU?

It doesn't really make sense that a game could improve by 80% unless something else were drastically wrong.

A graphics driver typically only takes up 10-30% of the total CPU cycles in a frame, so even if you were able to offload that to another core in full (which isn't the case here, it's just multi-threading so this is like a best-case measurement), the game could only spit out maybe 40% more frames with those extra CPU-cycles on that core where the driver used to be running along-side the game.

I'm not saying it's impossible, I just can't figure it out, so color me boggled.
 
8.12 increased my performance considerably in crysis, 20% at least. All other games also feel much smoother. The problem is that I get bsod's when even thinking about making any enabling/disabling of crossfire changes and reboots when watching videos when both monitors are enabled. 8.10 was 100% solid before anyone starts about problems with my pc. Many others out there are getting the same behavior with 8.12. I find it strange that they released these drivers so close to when 9.1 should be out. I wonder why they didn't just wait to incorporate the fixes into 9.1? I too am waiting for 9.1 as a last straw. If all the problems with bsod's and multiple monitor issues, black screens, etc aren't fixed by then, I am selling the 4850's and going to a gtx285. Do or die time ati.
 
It really is true for me as well. The original 8.12 (non hotfix) is a HUGE performance increase for me over 8.10, and this coming from a guy that has had just about enough of ati's craptastic drivers. If they can fix the stability issues with 8.12 and incorporate them with the performance increases into 9.1 then they will have one fine bit of software and hardware and I will be extremely happy with my 4850's for a change. 8.12 really does make a huge difference though. I can actually run with 2xAA and 8xAF at 1920x1200 in crysis with half high/very high settings and get a solid 30+fps now. I could do that before but certainly not with AA turned on. AA makes ALL the difference in crysis and warhead. I am crossing my fingers for 9.1 because I hate like hell to drop 4 bills on a new video card if I don't have to...
 
The 5% performance boost i got going from 8.11 to 8.12 did not impress me in the least.
 
God damn i hate % numbers expecially 5% which could very much be a margin of error in testing.

However, in games like crysis which have very low fps it can make a difference, just hope that this is true. As a quad core/X2 user this could benefit me.
 
Are the driver tested the ones in the GTX295 article?
The improvements that the new AMD 8.561.3 driver includes over Catalyst 8.12 are:

* Call of Juarez improves up to 15% with AA enabled

* Company of Heroes improves up to 5%

* Crysis improves as much as 18%

* Crysis Warhead improves as much as 20-30%

* Need for Speed Underground improves as much as 70%-80%

* World in Conflict improve as much as 5%

Ah it all makes sense now, and the 80% increase makes sense too. It's improved Crossfire scaling, not improved single GPU performance :p
 
The crysis ones look interesting just because that 's a 1/5th more frames which will translate into far more playable if you like playing crysis, which i do up to the alien part.
 
^ Yep, if you check out our GTX 295 evaluation you will see the Crysis improvements have allowed me to play at "Enthusiast" at 1920 with 4X AA.
 
Does anyone have an ETA on 9.1, and how did we get to 9.1 from this hotfix thread :D.

Check out the review at computerbase. They used the 9.1's. Big gains in some titles.

According to the review the 4870X2 is the better card due to price/performance. Heck it's better at high res with AA and AF. I was honestly expecting more out of the GTX 295.

As for Catalyst 9.1, it doesn't bring improvements to Deadspace it would seem.
 
When applying a hotfix, do you have to go through the whole rigamarole of uninstalling the driver, using driver cleaner etc., or do you just apply the hotfix? Also, would this apply to an x2 card, or just if there are two cards in cross fire (i.e., does the x2 count as cross fire?).

I didn't and it worked fine (just installed over old drivers),

It does apply to X2.
 
You don't have to do any of that for normal driver installs unless you have stability problems.
