Drivers & ISV Relations
As we noted last week with the release of the Catalyst 12.1 preview, AMD has a lot of technical and reputational debt to dig themselves out of when it comes to their Catalyst drivers. AMD dropped the ball this fall a number of times, failing to deliver on appropriate drivers for Rage, Battlefield 3, and The Elder Scrolls V: Skyrim in a timely manner. This isn’t something AMD is shying away from either – they know they screwed up and they’ll admit as much – but the question remains of how they intend to improve from there. Now that they once again have the leading single-GPU video card they need to have the leading drivers to run it.
Part of this redemption will come from the addition of new features, if only to reach parity with NVIDIA. Catalyst 12.1 introduced custom application profiles, while as we discussed with Eyefinity, Catalyst 12.2 will add to AMD’s suite of Eyefinity features with custom resolutions and the ability to relocate the Windows task bar. Furthermore AMD has features in the development pipeline for their Catalyst drivers for introduction later this year, but at this point it’s too early to talk about them.
But new features alone can’t fix every single thing that has ailed AMD in the past year, so the question remains: how does AMD intend to fix their poor delivery of optimized drivers for new games? It’s a question AMD cannot (or will not) completely answer in detail, but it’s a question for which there’s at least part of an answer.
The fundamental answer is more. More developers, more quality assurance, and above all more money. By all accounts NVIDIA sinks a lot of money into driver development and ISV and it usually shows. AMD is going to spend more resources on driver development at home and this is going to help a great deal, but at the same time it would seem that they’ve finally come to realize that great ISV relationships require that AMD be more proactive than how they’ve been in the past.
ISV relations covers a large umbrella of activities. Not only does this mean providing support to developers who request it, but it means providing cross-promotion marketing, encouraging developers to make use of your features (if only to help spur the creation of the killer app), and actively seeking out important development houses so that AMD’s interests and concerns are represented and represented early. It’s been said that the most important thing NVIDIA ever did with ISV relations was to send out their own engineers to development houses on their own dime to provide free support – essentially investing at least a small amount of money into a major game. The payoff of this was that NVIDIA was literally there to represent their interests, and conversely they had a chance to evaluate the game early and get to work on optimizations and SLI support well before it shipped. Snark about TWIMTBP aside, that’s where NVIDIA has raised the bar with ISV relations. That’s what AMD needs to follow.
To that extent AMD has reorganized the budget process for their ISV relations department. Neal Robison, the director of ISV relations, now directly controls a much larger ISV relations budget, whereas previously the ISV relations budget was apparently controlled by several parties. Having more funding for ISV relations won’t solve AMD’s issues on its own – It’s all about how that money is spent – but clearly AMD is on the right path by being able to afford to be more proactive about their ISV relationships.
Whether these changes will pay off as AMD is expecting them to remains to be seen, but from our discussions it’s apparent that AMD is trying harder than ever before. A great product requires good hardware and good software; AMD has the former in Tahiti, now it’s time to see if they can deliver on the latter.
Closing out the subject of drivers, AMD is also using the Southern Islands launch to outline their plans for Windows 8. AMD is promising that they will deliver drivers for Windows 8 on the same schedule as they have for Windows 7 and Windows Vista – new drivers will be available for the Windows 8 Beta, RC, and RTM releases. Furthermore as Microsoft has continually iterated on the WDDM driver stack since Vista, AMD will continue to be able to offer a single unified driver that covers all of the WDDM OSes (Vista, 7, and 8).

Ryan,Thanks for the great review. My only gripe - and I've been noticing this for a while - is the complete non-mention of drivers or driver releases for Linux/Unix and/or their problems.
For example, Catalyst drivers exhibit graphical corruption when using the latest version (Version 3) of Gnome Desktop Environment since its release before April. This is a major bug which required most users of AMD/ATI GPUs to either switch desktop environments, switch to Nvidia or Intel GPUs, or use the open source drivers which lack many features. A partial fix appeared in Catalyst 11.9 making Gnome3 usable but there are still elements of screen corruption on occassion. (Details in the "non-official" AMD run bugzilla http://ati.cchtml.com/show_bug.cgi?id=99 ).
AMD have numerous other issues with Linux Catalyst drivers including buggy openGL implementation, etc.
Essentially, as a hardware review, a quick once over with non-Microsoft OSs would help alot, especially for products which are marketed as supporting such platforms.
Regards,

Why in the heck would they mention Linux drivers and their issues in an article covering the (paper) release and preliminary benchmarking of AMD's new graphics cards? It has nada to do with the subject at hand.Besides, hardly anyone cares, and those that do care already know.

And I guess that AMD GPUs are sold as "Windows Only"?Thanks for your informative insight.

There are no games for *nix and everything always depends on your distribution. The problems are so diverse and numerous.. it would take an entire article to briefly touch this field.Exagerating, but I really wouldn't be interested in endless *nix troubleshooting. Hell, I can't even get nVidia 2D acceleration in CentOS..

You have a valid point on that front and I agree, nor would I expect such an article any time soon.However, on the other hand, one would at the very least expect a GPU using manufacturer released drivers to load a usable desktop. This is an issue that was distro agnostic and instantly noticeable, and only affected AMD hardware, as do most *nix GPU driver issues!
If all that was done during a new GPU review was fire it up in any *nix distribution of choice for just a few minutes (even Ubuntu as I think its the most popular at the moment) to ensure that the basics work it would still be a great help.
I will have to accept though that there is precious little interest!

Hi Chiddy;It's a fair request, so I'll give you a fair answer.
The fact of the matter is that Linux drivers are not a top priority for either NVIDIA or AMD. Neither party makes Linux drivers available for our launch reviews, so I wouldn't be able to test new cards at launch. Not to speak for either company, but how many users are shelling out $550 to run Linux? Cards like the 7970 have a very specifically defined role: Windows gaming video card, and their actions reflect this.
At best we'd be able to look at these issues at some point after the launch when AMD or NVIDIA have added support for the new product to their respective Linux drivers. But that far after the product's launch and for such a small category of users (there just aren't many desktop Linux users these days), I'm not sure it would be worth the effort on our part.

Hi Ryan,Thanks very much for taking the time to respond. I fully appreciate your position, particularly as the posts above very much corroborate the lack of interest!
Thanks again for the response, I very much appreciate the hard work yourself and the rest of the AT team are doing, and its quality speaks for itself in the steady increase in readers over the years.
If you do however ever find the time to do a brief piece on *nix GPU support after launch of the next generation nVidia and AMD GPUs that would be wonderful - and even though one would definately not buy a top level GPU for *nix, it would very much help those of us who are dual booting (in my case Windows for gaming / Scientific Linux for work), and somewhat remove the guessing game during purchase time. If not though I fully understand :-).
Regards,
Ali

Nvidia consistenly wins over and over again in this area, so it's "of no interest", like PhysX...AmdInside - Thursday, December 22, 2011 - link
I won't be getting much sleep tonight since that article took a long time to read (can't imagine how long it must have taken to write up). Great article as usual. While it has some very nice features, all in all, it doesn't make me regret my purchase of a Geforce GTX 580 a couple of months ago. Especially since I mainly picked it up for Battlefield 3.ET - Thursday, December 22, 2011 - link
The Cayman GPU's got quite a performance boost from drivers over time, gaining on NVIDIA's GPU since their launce. The difference in architecture between the 79x0 and 69x0 is higher than the 69x0 and 58x0, so I'm sure there's quite a bit of room for performance improvement in games.Have to say though that I really hope AMD stops increasing the card size each generation.
