Any chance this will work with an ASUS Ares II? Remounting this card and its radiator really isn't something I want to do unless there's some indication that this new driver will work. Anybody else who owns one of these cards knows exactly what I mean.
There's no indication as to why it wouldn't work - It is made for exactly these setups, 99% sure it will work.

The new graphs look great Hilbert, good job.

Great review, Hilbert. Will give the drivers a spin this weekend. Thanks. 🙂

Thanks Hilbert. I'll be remounting the Ares later today, whenever I can make a little extra time. The new Bioshock Infinite DLC should make a nice test for it.

"This first 13.8 beta only supports framepacing in DX10 and 11 games and is compatible with Windows Vista, 7, 8 and 8.1 in the first phase" Sure 8.1 is supported? Windows unable to detect driver package under installation.. Windows refuses to let me manual install from .inf from device manager.
There's a tricks for it, go see in the AMD driver thread, 13.8 .. ( need move a folder )
Been watching for reviews and articles for hours since the driver release. Amazing stuff. I'd like to know how previous generation Nvidia GPUs do in frame pacing as those allegedly have hardware-based frame metering. This idea is confusing me since microstutter was apparent before Kepler yet even G80 had hardware for that stuff.
In reality, the commonly called micro stutter and frame rate timing behaviour are not the same thing.. ( well it can be a cause of micro stutter, in extreme case, ( when you have some frames at 89ms and some at 8ms just before ). Anyway, Nvidia have never use it before Kepler.. The story is more complex than that .. and its not really easy to get the full picture without been able to test ourself ( cost too much money )

Actually i think APU CFX are not supported yet by this driver( or not in all hardware setup )... The thing is a bit more complicate ofc in the case of the GPU" inside the CPU " + a "standard GPU" CFX. I can understand they will need a bit more time.

What? Of course they aren't the same thing. I meant they had hardware to DEAL with the issue, by frame pacing / metering.
Anyway, Nvidia have never use it before Kepler..

Improved Frame rate Metering Kepler introduces hardware based frame rate metering, a technology that helps to minimize stuttering. In SLI mode, two GPUs share the workload by operating on successive frames; one GPU works on the current frame while the other GPU works on the next frame. But because the workload of each frame is different, the two GPUs will complete their frames at different times. Sending the frames to the monitor at varying intervals can result in perceived stuttering. The GeForce GTX 690 features a metering mechanism (similar to a traffic meter for a freeway entrance) to regulate the flow of frames. By monitoring and smoothing out any disparities in how frames are issued to the monitor, frame rates feel smoother and more consistent.

Yep that was introduced with kepler. G80 had microstutter in sli mode. Had 2 88gtx

Excellent drivers so far even in single GPU setup, nice to see improvements for us single card users too along with the much anticipated frame pacing fix. Next up should be the memory management rewrite for GCN and AMD will be 100% back on track. Its awesome to see how much they have improved things with what is technically just a software hotfix implemented into these drivers, to match or even better Nvidia's hardware based solution is just very impressive indeed. As always great article Hilbert!

@Spets: Source for Nvidia never using that hardware before Kepler. @TK: I know, that's why I am confused. If the hardware was there, why was there apparent microstutter?

thats the first I am hearing it TBH, I had awful microstuttering on a couple 295`s too

3 Things: 1. Amazing, over the top work Hilbert! Uitstekend! :thumbup::thumbup: 2. Love my 690! :P 3. As Hilber said: Credit should be given where credit is due. WELL DONE AMD! Well done. Lets hope they continue like this. :thumbup:
