AMD Framepacing Catalyst 13.8 driver examined with FCAT

In today's article, we analyze the new AMD Framepacing Catalyst 13.8 beta driver in combination with FCAT.

In our recent FCAT benchmarking article from April we already exposed that AMD Crossfire solutions suffers from a phenomenon called micro-stuttering.

A problem that is often hard to see, but has been known for years and something both AMD and NVIDIA have had.

NVIDIA solved the issue starting with Kepler based graphics cards.

With a new technique called FCAT (Frame Capture Analysis Tool) was introduced, a whole lot of micro-stuttering was exposed for AMD, putting them on severe pressure to release a fix for this.

@Thracks,

thanks for the feedback earlier, top man, glad to see your keeping an eye out in here.:)

Ultimately we have to give AMD the kudos they deserve. They have come forward about their issues, set out a plan to fix them, and have begun delivering on those plans. There’s still room for further improvement within AMD’s drivers, so AMD’s job is far from done, but today they have taken the first step needed to settle the frame pacing problems that have been dogging their products.

We are going to give credit where credit is due as AMD deserves that. In a relatively short time period the driver team has been able to tackle micro-stuttering significantly.

In a 4 months time-frame, AMD has been able to make very significant improvements to multi-GPU rendering, eliminating that dreaded and much discussed effect called micro-stuttering. If this implementation works on all games and future games then I have no reservation recommending AMD multi-GPU solutions any longer. The output AKA rendering quality you retrieve on your monitor is very good.

I shall have a try out later tonight and see what's what.

Well done neil, the man who remains absent sent me this too:

right so tooks ages for me to install it, kept having an issue when installing it, eventually got it done, and my first test has me stumped, I was benching tomb raider earlier (with the settings dictated in the tomb raider benchmark thread) nad was getting results around: min - 73/max - 122/avg 96.6 (screen shot if required I have)
but with the new drivers Ive been getting min 60/max 91/avg 75 - this is with frame pacing both turned on and off? I was doing the benchmarks earlier today and nothing has changed - same gpu and cpu clocks - effectively Ive lost an average of 20 fps from these drivers on tomb raider - havnt tried anything else as of yet - anyone having similar results?

Nice of them to think of all their eyefinity users who are probably the main users of multi GPU setups, in relative terms. I presume this support will come latter but I'm glad I didn't waste my time wating around for these, I would not have been impressed!

I expected these to support Eyefinity as well, seems that's not the case. :mad:

The spec for a 79x0 graphics card lists res support the same way, I think they just mean "each monitor attached to your card/s".
