Vista Crossfire/SLI hotfix

[Flying Gribble]

Microsoft have just issues a hotfix for slow performance with linked display adapters.

SYMPTOMS
In some scenarios, games and benchmarks perform more poorly than expected on a Windows Vista-based computer. This issue occurs when the games and the benchmarks use multiple display adapters in a Linked Display Adapter (LDA) configuration.

and

SYMPTOMS
Consider the following scenario:
• You have a Windows Vista-based computer.
• The computer uses two or more DirectX-compatible graphics processing units (GPUs) in a linked configuration.
• You are using a DirectX 10 application and driver.
In this scenario, the computer's graphics performance indicates that only a single GPU is being used.

Hhm, but does it actually work?
I thought they already had a Vista SLI hotfix?
I tried it and it made no difference - gaming still miles better* in XP.



*better as in better FPS.

Dunno, only got 1 card myself!

I just ignored when I see today as there was already one months ago but you had to go looking for it + I dont have dual GPU's

I've requested the 32-bit and the 64-bit versions. Will host a mirror when I receive them.

ok cool..will see what it's like once you have one up

So just 1 of me cards are being used in DX10?

No, that would be KB936710, not KB945149. God only knows why OP is confusing the issue by quoting a completely different hotfix that's already been released.

 

[metalmackey]

Will it fix my low 15k 3Dmark 06 score?

I was quoting it because it's referenced in the hotfix text under the "MORE INFORMATION" section. There ya go - now you know as well as God.

I've got the two fixes (x86 and x64) now, if anybody wants them without having to resort to asking microsoft, let me know.

 

[metalmackey]

Didn't make any difference to my framerates whatsoever.

 

[paradigm]

I haven't had time to test, was going to at the weekend (before I flatten vista and install XP to see if I can't get closer to the no.1 spot in the 3dmark06 list).

Did it make no difference at all, like stability in games that used to have issues with LDA (linked display adapters)? I'm hoping that at the least, it will solve my issues with TDU and crossfire.

 

[metalmackey]

How much lower is 3dmark 06 in Vista compared to XP?

 

[paradigm]

I'm not 100% sure yet, as I haven't had XP installed on this machine, ever.

Judging off similar systems on the ORB, I can expect a 1000+ point increase though.
