AMD Frame Pacing Explored: Catalyst 13.8 Brings Consistency to Crossfire
by Ryan Smith on August 1, 2013 2:00 PM ESTCrysis 3
Our final benchmark in our suite needs no introduction. With Crysis 3, Crytek has gone back to trying to kill computers, taking back the “most punishing game” title in our benchmark suite. Only in a handful of setups can we even run Crysis 3 at its highest (Very High) settings, and that’s still without AA. Crysis 1 was an excellent template for the kind of performance required to driver games for the next few years, and Crysis 3 looks to be much the same for 2013.
Our last game and our last flip. AMD and NVIDIA exchange places one final time, with the GTX 690 and 7990 swapping out so that the GTX 690 takes the lead.
Crysis 3 is another game where AMD’s initial position wasn’t quite as bad, and consequently the improvements aren’t as great. 19% gets them to the acceptable range on the 7990, while at the same time with only 4 percentage points separating the 7990 and GTX 690 means that this is the closest the two cards have ever come to matching each other in frame time consistency.
Graphically we can see that both AMD and NVIDIA still struggle with consistency to some extent. GTX 690 in particular has a short run of very high variability about 10 seconds in that AMD doesn’t experience, likely due to their hard cap on minimum frame times.
Finally on the matter of 95th percentile times, our data here mirrors what we’ve seen earlier. AMD shows a smaller gain, with their final value of 20.7ms still leaving them a couple of milliseconds behind the faster GTX 690.

Are you still signed into AOL...? ;) I also haven't had many issues with either, at least from a single GPU perspective.kyuu - Friday, August 2, 2013 - link
What a surprise, the AMD-bashing trolls are out in force with long rants that nobody will read.Give it a rest guys.
Anyways, great write-up Ryan. Good to see AMD is getting the issue taken care of.

Except in this case, "AMD bashing trolls" helped fix your CF drivers. A simple "thank you" would have sufficed.TheJian - Tuesday, August 6, 2013 - link
ROFL...I sincerely thank you for the laugh ;)I liked many products over the years but have been saved by vocal complainers pointing out things to make me run, or at least wait until fixes come. I waited for RROD to get fixed with Jasper. Years of complainers finally got a fix (it took so long I started doubting I'd ever own one). My friend who jumped on x360 early shipped his back multiple times in the first year. I believe it spent more time at MS than in his house...LOL. He was a vocal complainer in their forums etc but I never called him a MS bashing troll for it. I laughed and thanked him for being one of the people who saved me years of that frustration :) He only thought that was funny after some beers...LOL
Thankfully he has a great sense of humor. He's ready with forum accounts everywhere he thinks the complainers will be for xbox1 this time (complainers have value people). But he expects to be a reader this time rather than the complainer ;) I think he'll go PS4 in the end despite the MS love he has vs. Sony. His wallet has no trouble voting against his fanboy thoughts.
I'm torn over the consoles though. I'd love to see AMD start making some cash, but at the same time I'm pretty unhappy they blew a wad of R&D money on something I want completely dead instead of cpus/gpus/arm socs. Had that R&D went to PC's I don't think I'd be making these statements dissing AMD. At the least they could have kept the layoffs from happening (losing 30% of your smartest people will shaft us on PC's for a few years at least and longer if consoles don't take off by the millions), and had good drivers all last year. That also might have given them a better reputation thus not needing to give out free games that are clearly wiping out profits (Q report shows this). AMD has a great gpu. It's a pity they didn't have enough funding for R&D to pair it with a great driver from day1 and funding to avoid the Fcat disaster. Even if it affects a small group it causes a lot of people to paint your other products with that image.

Interestingly enough, I seem to remember my GTX 460s having microstutter and performance issues in SLI. To the point where your experience in twitch games would be better if you just disabled on of the GPUs. However, over the years, and many driver updates, I don't seem to notice it any more. Nvidia really must have quite a talented software team, who communicate well with the hardware division. I would say there might be some kind of company structure issues for an issue such as this to go unnoticed, and un-fixed for such a long time.anubis44 - Friday, August 2, 2013 - link
Ssshhhhh! TheJian will be all over you like a duck on a june bug! Remember, Nvidia's drivers are always perfect! They never make any mistakes......well, except for the chronic problem I had with the GTX670 card I bought for my 3 monitor setup - kept requiring about 20 steps to get all three screens to display due to bad default refresh rate/synch issue in the Nvidia driver. Got so frustrated having to go through 20 steps every time I updated to a newer driver that I sold the card for close to what I paid (~$400) and bought a Gigabyte 7950 for about ~$100 less and flashed the bios to 1050MHz. 3 monitors in eyefinity set up in about 5 minutes in the Catalyst control panel and not a problem since.

Are you using display port monitors or an active DP-DVI adapter for your third monitor? If the latter, has it finally gotten plug and play vs the problems when it first came out? I was never able to get an adapter to work with my 5870; and since my setup wasn't EF compatable anyway (2x 1200x1600 1x 2560x1600) ended up cutting my losses with a 5450 for the 3rd monitor and went nVidia for my next GPU in response.krutou - Friday, August 2, 2013 - link
Nvidia is known to suck at multi-monitor support because AMD was the first to develop the technology. One of AMD's few strengths is Eyefinity support.TheJian - Tuesday, August 6, 2013 - link
From the article (and this is repeated at every site reviewing the drivers):"So what’s being addressed in phase 1? Phase 1 is being dedicated to Direct3D 10+ games running on a single display. What’s not being addressed in the first driver are the Direct3D 9 and OpenGL rendering paths, along with Eyefinity in any scenario."
So Eyefinity has issues and isn't even touched with phase1. At the very least AMD is the opposite of strength with eyefinity for now. Phase2 maybe? ;)

You've stated a point without backing it (4th, green).
Refutation:
I found your mistake and explained why it is one and backed it with a direct quote (from this article no less...ROFL) thus proving my point ;) That's the purple one :) But I'm pretty sure I made it into the grey anyway. Your central point is debunked. But I can live with purple if it makes you feel better.
Being first has no bearing on who is better later. Horses got us from point A to B first, long before cars right? But that didn't stop a car from blowing them away later. I could say the same about the first car engine vs. say a Lamborghini engine today. First doesn't mean best.

Why, he's pointing out reality and what most sites point out. All multi cards had issues for a while and still do. NV just spent a lot more to come up with the tools/software to fix it as best as possible (and I'd still go single potent vs. even NV multi given a reasonable choice). You're mistaking an accurate product complaint for fanboyism. That is not what my complaints are. There is no reason to attack his comment as I already know it's at least partially true for all CF/SLI and the fix is proven (so is AMD's lack of it up to now, and still having issues with 3 cards).Would you feel better if I ranted on Bumpgate for a few paragraphs? When a company sucks I point it out. I don't care who it is. Caminogate anyone? I ranted then too. Win8, don't get me started, Vista...(fista? Nuff said). I have equal hate for all crappy releases no matter how much love or hate I have for a company (I hate apple's tactics & pricing, but they do generally have a good polished product). If AMD releases a great 20nm product and NV sucks I will RAVE for AMD and shout at the top of my lungs how NV's product sucks. Based on R&D I doubt NV will suck but AMD can still get out a good product, I just need proof at this point due to lack of funds/engineers pointing to a possible problem launch again.
Comically you miss the entire point of any of my posts (which are backed by data from other sites etc), then rant yourself on NV. Congrats though, at least you made it to the 4th rung here (well sort of):

But not without making the 2nd worst type of argument first...ROFL. You're not outing me here, you're outing yourself.
