Potential Crossfire Fix coming? (Catalyst 13.5)

Catalyst 13.5 rumor

http://www.overclock.net/t/1382725/catalyst-beta-13-4/20
Few more Crossfire profiles and optimizations vs the current 13.3 beta. It also has a new component that will reduce stuttering and frame time deviations generically across DX10/DX11 engines

Here's my prediction if either rumor is true (24th 7990/13.5 driver crossfire fix):

7990 paper release the 24th, released in May with 13.5 crossfire fixes.

Sounds good. AMD seems to be getting good a CrossFiring their Radeons now. Less microstuttering will only help AMD GPU sales.

Let's hope 😀

Evidently the guy on OCN had been using them...

Now we're getting breaking news about Catalyst rumors?
AMD Serbia STRONG @ AT VCG 😱

As explained by D. Bauman, don't expect a single miracle driver. Getting things right is a process.

And dont forget to say BIG Thank You to Techreport, PCPER and Alienbabeltech.
If it was up to you kooks, AMD would have never even looked into latency issues.

Crossfire has been broken out of the box for years, the fact that AMD eventually acknowledged it was a long time coming.

Someone pee in your Wheaties? And who is "you kooks" referring to?


Back OT - Hopefully the 13.5 drivers really have the Crossfire fixes. Probably too early for the switch AMD is going to add to CCC which allows users to turn frame-metering on and off.

Nice troll fail.

When have I objected to looking into stutter?

I didn't think so. Back to your cave now.
 
Interesting rumour, but let's wait and see before getting too excited.

For the record: "a new component that will reduce stuttering and frame time deviations generically across DX10/DX11 engine" is NOT the same thing as a "Crossfire fix." What needs to be fixed in CF is microstutter caused by AFR. What is described in quotation marks refers to SINGLE-GPU frame time problems, not multi-GPU problems.
 
Highly unlikely this will be a direct fix to CF issues.

I'm hoping the fixes increase performance, and that it comes out or gets leaked soon, been running 13.3 since I got my card.

Your already chewing through everything out there and you want more performance?
 
I would want more too, but I am still running a q9550 and ddr2 800 on a 775 board.. so ... I need haswell....
 
ftfy, I think 13.5 is going to be that all in one fix driver though. Since they are taking quite a while on this release, they are possibly rewriting the memory controller.

I hope so, I mean it'd be nice, but I wouldn't get my hopes up. Then again, I'm one of those blind AMD fanboys that isn't affected by all the earth shattering frame latency BS affecting AMD, that was recently uncovered by Nvidia.
 
expected overall performance to drop about 25%. frame cap profile will be added across the board for all current games.

not rocket science.
 
I suspect they can come up with a better plan than 25% frame cap.

If I were doing this, I'd track the frame rendering time of the previous 5 frames (test as few as 3 or as many as 10 to see how it works), and add some time to any frame which is ready to be displayed at less than 30% of that average from the previous frame (50% is perfectly even frame spacing). This will prevent any two frames from getting too close to each other, and not be overly aggressive in delaying FPS. Of course you can test different numbers to see what gives the best balance.

It doesn't seem like it should be difficult to do, unless the internal hardware isn't capable of measuring the time it starts to render a frame and then display it.
 
For single GPUs they don't need to add metering really. If they just fiz the bug(s?) That are causing the present call in directX to come back at very inconsistent moments then that will fix the stutter. Last I saw that was related to poor garbage collection not a lack of metering.

For crossfire something different will be needed, some amount of metering to initially separate the cards and then a process to keep them separated as best as possible.

Alienbabeltech? LOL Please, there are only a select few converts that even click on that site. If you really want to thank someone, thank nVidia.

Yep, right on the money. Dunno about TechReport, but considering PCPer had "support" from NV for a while without revealing it and still is sponsored by NV, credit goes to NV. Also ABT has the NV sponsored trolls that get kicked out of other forums, credit to NV. TR doesn't have any known ties to NV afaik.

So in conclusion, (if it even gets fixed) thanks NV and TR.

In the end everyone wins but phisherman can't accept there is a thread on this topic which could potentially be the biggest topic before next gen cards come out.
 
LOL at the thank NV comments. Crappy crossfire performance and stutter problems have been mentioned by sites like [H]ardOCP for quite some time before TR or PCPer mentioned anything. My own eyes and crappy game performance with 7970s in XF made me switch to NV long before the supposed NV help. Give me a break.
