Amd Makes A Breakthrough In Improving Frame Latency

[Jozi]

AMD has been criticized by some tech publications over Radeon HD 7000 series posing higher frame-latency over NVIDIA GeForce chips, even in cases where AMD's chips offer higher frame-rates. "Frame latency" or "frame time" was purported as a metric of the same importance as frame-rates, in graphics card reviews. Various essentially identical methods were used to show that AMD Radeon GPUs yield higher frame latency (time taken for frames drawn by the GPU to make it to the display) than NVIDIA GeForce ones, even in cases where AMD's chips offer higher frame-rates. AMD has apparently made a significant breakthrough in improving frame latency.

In January, AMD made its first official response to early tests that showed Radeon GPUs to pose higher frame latency. In its defense, AMD stated that frame-latency issues are not a hardware design flaw, and can be ironed out by optimizing drivers to the redesigned memory controllers on GPUs based on its Graphics CoreNext architecture. Sources told us that AMD is ready with its first prototype drivers that fix frame latency issues. These drivers are pre-alpha, and are made available to select industry partners, with an adequate level of competence and expertise, since a week now. After AMD takes feedback from these partners, the company will begin rolling out the first beta drivers, followed by WHQL-signed ones.

Very cool I am glad to see AMD fixing this issue because it was a big problem for AMD GPU owners especially in Crossfire.

Awesome!

AMD is doing a really great job at improving the gaming experience. Proud to be the owner of an AMD graphics card.

yep,amd now is great.

I had a gtx680 but I was having alot of problems with fluidity in BF3 even with good fps then i changed for the  asus HD7970 and is another league,the BF3 is fluid like never before.

But I had to return the asus 7970 direct cu TOP because was voltage locked,now I will wait too see if amd counter the gtx 700 series with the HD8000.

It's crucially important to state that the frame latency issue is only relevant and prominent with multi GPU setups namely crossfire & SLI, both have frame latency issues although crossfire has it worse.
With a single GPU card like the 7970 or the 680, the frames drawn by the graphics cards (fraps method) equal the frames displayed by the screen (perceived) and there is no disparity between the actual performance of the card & what the user sees.

very true. nvidia has a new beta for sli profiles. 660 supposedly gets 15%% better fps across the board, hopefully that translates to my 660ti's, because i can't do ultra in hawken without going below 40 :(

 

edit: so even sli has it's issues, but adaptive vsync kinda destroys them :P

RadeonPro's Dynamic V-Sync also resolves the frame latency issue on Crossfire setups.

I am very excited for this, I really hope it improves my experience with my wonderful HD6990...

But it gives a lot more input latency, so not really an option for some people. Also, Vsync does not work in eyefinity!
