AMD Frame Pacing Explored: Catalyst 13.8 Brings Consistency to Crossfire
by Ryan Smith on August 1, 2013 2:00 PM ESTHitman: Absolution
The second game in our lineup is Hitman: Absolution. The latest game in Square Enix’s stealth-action series, Hitman: Absolution is a DirectX 11 based title that though a bit heavy on the CPU, can give most GPUs a run for their money. Furthermore it has a built-in benchmark, which gives it a level of standardization that fewer and fewer benchmarks possess.
Again there’s nothing really new here. In the previous game the GTX 690 led, while in Hitman the 7990 leads.
Moving on to our delta percentages, we again see the gains AMD has made with their frame pacing implementation, though Hitman was one of their better games in the first place. Consequently they’ve shaved off 11 percentage points, from 31 to 20, just enough to reach our 20% threshold but no more. This is still 13 percentage points worse than the GTX 690 however, so much like Shogun there’s still clear room for further improvement.
Meanwhile the FCAT graph data shows the same thing we saw with our numerical analysis, with the 7990 showing a much greater degree of variability. AMD’s frame pacing mechanism seems to be much less present here than in other games, with the adaptive window less noticeable here than elsewhere, perhaps due to the relatively high variability.
The smaller gains with regards to deltas are reflected in a much smaller improvement on 95th percentile times. Though in this case at the 95th percentile the 7990 is competitive with the GTX 690.

Not aimed at anyone, but flat out in any competitive game play the kind that has tourneys and pays out cash, Mostly fps such as quake..etc everyone has vsync off it flat out adds input lag...all the pros turn it off no matter what monitor is used, but no one is running a SLI/CrossfFire set up during these events.The pros typically lower settings quite damn low so they can push a steady 125fps and screen tearing is absolutely no concern. And if i have vsync on my aim % takes a nearly 25% dip
Anyway this is review is about duel+ cards, and kudos to AMD even though they still need a bit of work before going on a official non beta release = )

can you check a10- 5750m with hd6670?dew111 - Friday, August 2, 2013 - link
I just got a second HD 7950, and this driver makes a HUGE difference! They should have done this earlier, but their timing was great for my first CrossFire setup :PJamesWoods - Sunday, August 4, 2013 - link
It's a crying shame they won't jump back to HD 4000 series or even HD 3000 series and fix these problems. I'm sure there is still quite a large loyal fanbase using these cards. I happen to own several systems with HD 4850's in them, and they can still set pace on a lot of modern games. Crossfire is another story. They never really felt optimized running in X fire.medi02 - Tuesday, August 6, 2013 - link
Is it me, or does nVidia have much lower min fps on a number of charts? =)transphasic - Tuesday, August 6, 2013 - link
Well done, AMD! You didn't bother to do anything about creating fixes for the single GPU setup, and basically ignored those w/o CF setups.You had 2 1/2 months without any new driver fixes, and THIS is the BEST you can do?
Major fail once again.
Thanks for nothing....

Exactly which single GPU setup is giving you micro stuttering problem?usrevenge - Wednesday, August 7, 2013 - link
Basically, AMD did a lot to fix the problems, but still leaves a lot of work to be done. I call these drivers a success.Nearox - Monday, August 26, 2013 - link
Does this technology also apply to the HD6000 series (and in particular the HD6950)? Could anyone say if this will also work for Skyrim? Thinking about getting a 2nd hand hd6950 to go xfire with this, seeing the good results from this AnandTech test.lopper - Wednesday, August 28, 2013 - link
A question: Does this driver fix stuttering on dual graphics configurations like A10 +6670?
