AMD Driver Caveats and Major Open Issues

The issues with AMD's driver and hotfix for Far Cry 2 have been fairly public. The 8.10 driver didn't really deliver on some performance points while the first hotfix had some rendering issues. The next couple hotfixes fixed some things and broke others, and we still don't have a driver from AMD that gives us the results we want. The 8.11 driver only incorporates the final hotfix changes, but we will have to wait until a newer hotfix is released or 8.12 for any hope of a better experience on Far Cry 2 with most AMD hardware.

While people have been talking about the issues, we've spent quite a bit of time looking at this problem (and the AMD driver issues are one of the major reasons this article is as delayed as it is). And we'll lead off with the bottom line: the Radeon HD 4870 1GB is the only AMD card not in some way afflicted, and it also happens to be the card we would recommend for the best single GPU experience on Far Cry 2 at any setting except 2560x1600 with 4xAA. But that is not an excuse for the kind of horrific experience we've had with every single other AMD solution when playing this game.

The stuttering issue people have pointed out with AMD hardware is not an issue with the 1GB part in our experience. The rest of the line up suffers greatly from random hitches that aren't so much stuttering in our tests as they are temporary slow downs. We were also unable to test CrossFire, as CrossFire only works with 4xAA enabled. Even then CrossFire performance is erratic and stutters more than single card solutions (except for with the 4870 X2 or two 1GB 4870 cards that is). We aren't quite sure what the CrossFire issue is, but it seems clear that there is some graphics memory issue somewhere, and not only because of the huge discrepancy between the performance of the 4870 512MB part an the 1GB part.

In our tests, we initially wanted to take the 3 run average for each test. This was not something we could do with AMD hardware as even our benchmark sessions were marred with ridiculous stuttering and slow downs. We would have performance range from 25 to 55 frames per second on any given test. Rather than take the average, we decided to take the highest performance run for NVIDIA and AMD. It is worth noting that most of the performance results for NVIDIA were within less than a frame per second difference, so average versus max performance run isn't that different.

This does mean that our tests paint AMD hardware in a better light than the actual experience will be, at this point in time, with every card except the 4870 1GB. The average FPS data was just not usable as our line graphs looked more like sine waves than anything logical; nothing made any sense at all. Our choice to publish this article now is based on the fact that we absolutely expect AMD to fix their performance issues in Far Cry 2 as soon as possible. Far Cry 2 is a major title and AMD is a major GPU maker: there is simply no excuse for this sort of problem.

So the trade off for going forward with best-case scenario numbers is this page explaining the problems and a plea to AMD to change their approach to driver development for the good of the consumer.

Maintaining a monthly driver release schedule is detrimental to AMD's ability to release quality drivers. This is not the first or only issue we've seen that could have been solved (or at least noticed) by expanded testing that isn't possible with such tight release deadlines. Yes, consistent and frequent driver releases to improve compatibility and performance are a necessity, but doing anything to excess is a very bad idea. Moderation is key and AMD severely needs a better balance here.

We've been mentioning this as an issue in passing when it pops up and causes us problems, but this is starting to get ridiculous. It is one thing when previous fixes are broken or when older games fall off the grid and are neglected. But when a major title like Far Cry 2 is released to incredibly poor driver support, it is time to wake up and realize that something is wrong. This is not the first time we've seen issues with a newly released game, but the problems we've had with AMD drivers and Far Cry 2 are some of the worst we've ever experienced.

And this time it isn't just us. This isn't prerelease hardware or a beta software package. This isn't a quick fix "oops I forgot something" kind of bug. Though we tend to see problems a lot more frequently than end users, we do see a lot more issues with AMD drivers than NVIDIA. Even though not all those issues are things that we need to bother end users with, the probability of hitting a bug that will affect end users is much higher when you've got a higher number of bugs to worry about in general.

Now don't get me wrong, AMD drivers are still much better than they were before Catalyst. Back during the transition to Vista, ATI drivers were hands and feet above NVIDIA drivers for a long time (and they didn't hang XP out to dry either). AMD has maintained a unified driver model where NVIDIA had to break up their driver for different hardware generations for a while.

And now it is time for AMD to learn from their mistakes and change over to a more manageable and sensible driver release policy. Double the time between driver releases, do much much more testing across hardware platforms and games, and maybe even regularly release partly QA'd beta drivers in between WHQL drivers if there's something that needs a quick fix.

    I'm using a 4850 1GB and I play on ultra high at 1920x1080 with 4 or 8x AA cant remember which. I've never experienced any slowdown but I'm using DX9.
  • gochichi - Tuesday, November 25, 2008 - link

    OK, so the 4870 1GB does a much nicer job than the 4870 512MB right? What about the 1GB variants of the 4850?

    I don't have this game, not sure I really want it for $50.00 (I would buy it at $20.00 for instance). I have a 4850 512MB and am generally amazed by how well it feeds my 1920x1200 monitor.

    Let's not forget that Crysis and Far Cry 2 are interesting benchmarks but they are not actually some of the better games out there (going by the reviews).

    If you haven't been playing Call of Duty 4 because your hardware isn't up to par, a better "$200 question" is how the new Call of Duty runs. COD4 is one of those few upgrade worthy games, I'm pretty sure that Far Cry 2 is not. I technically wouldn't have to upgrade my setup to run it, and I can't even bring myself to pay $50.00 for the game. I'm not sure that many of you out there would want to spend even more than $50 to run this game. Most of us can't be upgrading for any old system hog that is released.

    Of course, if you're shopping for a new video card and one of them comes with a game you're interested in, it's going to sweeten the deal. When I was shopping, I was almost lured in by one that had "The Witcher" included. I knew I wouldn't buy that game separetely but it sounded interesting enough to lure me. It's all about the package and the price. Would I recommend the 4850 based on my experience? Absolutely. But NVIDIA is a great company and has been catching up nicely with driver updates. The only beef I have against NVIDIA is that they've been renaming their old parts with new names and that is absolutely unethical. Heck, Nvidia's naming scheme is so bizzarre that a 8800GT 640mb is considerably worse than a 8800GT 512MB.

    Now, back to my original question... if the 4850 1GB does, in fact, perform substantially better than the 512MB one, I would think it would put it right at the top of the list for this game.

    Actually, nvidia's naming scheme is so bizarre that while I don't think there was an 8800GT 640, there was an 8800GTS 640 and an 8800GTS 512, and performance order went 8800GTS 640 < 8800GT 512 < 8800GTS 512. How is a customer supposed to make sense of that?
  • SiliconDoc - Friday, November 28, 2008 - link

    Yes, and the 9800GT with the bios updated old core - the 8800GT - or in the case of the Asus Ultimate (now sold out everywhere it seems ) the 8800GTS - then the ddr2 vs ddr3 - not to mention that smae issue with ATI - now ddr2, ddr3, ddr4 - one has to be quite careful in what they finally purchase, huh. LOL
    Then you have the brands issues and the rebates and the OC issues - the ram type on the cards that overclocks better or not ...
    I think NV is still getting some review diss because of their confused naming convention which so many considered trickery or too messy to sort out - or time consuming... so I think there's part of the fan issue opposition.
    Nonetheless, I'm glad I chose what I did based upon price and package and all the research I could muster before purchase - I waited quite a while and luckily those 6 months saw a massive output of new card releases - I could have just as easily went with an ATI release with some great deal on price and a game - I'm sure it was my excellent skills but wouldn't argue much with someone calling it luck. LOL
    I see so often reading all over the net at all the popualr and unpopular places - ATI people chiming in that they don't have a problem... and I can't think of really a single case of an NV fan chiming in, in that fashion - so that tells me one thing....
    No matter how many ATI users have had zero problems their entire lives in any OS with ATI cards including any game ever made or thought of, the very fact they have to constantly tell everyone that means :> THERE'S A LOT OF OTHER PEOPLE HAVING PROBLEMS WITH ATI.
    I suppose I could be wrong, and instead - every ATI buyer is an absolutely masterous OS and game installer and configurator - and likewise all the uncomplaining NV users are oafs who are so noob skilled they can't properly install an ATI card to save their lives... NAHHHHHH !

    Can you please fucking die? Preferably by getting crushed to death in a garbage compactor, by getting your face cut to ribbons with a pocketknife, your head cracked open with a baseball bat, your stomach sliced open and your entrails spilled out, and your eyeballs ripped out of their sockets. *beep* bitch


    I would love to kick you hard in the face, breaking it. Then I'd cut your stomach open with a chainsaw, exposing your intestines. Then I'd cut your windpipe in two with a boxcutter. Then I'd tie you to the back of a pickup truck, and drag you, until your useless *beep* corpse was torn to a million *beep* useless, bloody, and gory pieces.

    Hopefully you'll get what's coming to you. *beep* bitch


    I really hope that you get curb-stomped. It'd be hilarious to see you begging for help, and then someone stomps on the back of your head, leaving you to die in horrible, agonizing pain. *beep*

    Shut the *beep* up f aggot, before you get your face bashed in and cut to ribbons, and your throat slit.

    You're dead if I ever meet you in real life, f ucker. I'll f ucking kill you.

    I would love to f ucking send your f ucking useless ass to the hospital in intensive care, fighting for your worthless life.

    I wish you a truly painful, bloody, gory, and agonizing death, *beep*

    Problem with stuttering can be removed by typing for example "gfx_maxfps 30" in console. Usually stuttering appears after loading a game, or when there is someone in a hut near you who you will have to talk to. On Catalyst 8.10 turning off the AA and typing this command fixes the problem. On 8.11 game works perfectly in 1600x1200, ultra detail and 2 times AA (with previously mentioned command). Sometimes when there are lots of things going on FPS drop to min 25, but it's still a great framerate for what you pay for this card and U can C in the game. Firstly I thought that it was something wrong with the vsync or that sort of stuff. It's definately a problem connected with memory buffer. I remember that ATI had similar problems in F.E.A.R. on their x800 series with 256MB but they have fixed it. For me FC2 on 4850 works as good or even better as it does on my friend's 9800GTX.

    Any word on what drivers were used for the nVidia cards?
    And what was the system used for these tests?? (memory/cpu/mobo etc)
  • Hawkmoon - Tuesday, November 25, 2008 - link

    I guess I missed it... or they updated the 2nd page.



    Before we get started, let's take a look at our test setup:

    Platform: ASUS Rampage II Extreme, Core i7-965, 6GB DDR3-1333, Intel SSD
    AMD Driver: Final 8.10 hotfix
    NVIDIA Driver: 180.44
  • rocky1234 - Monday, November 24, 2008 - link

    Well as I said in those AMD forums to a few guys there & this was after reading their posts or system configs is that alot of the time a lot of the issues are not from The video card or the drivers but from a badly configered system or a system that is overclcoked to far or even worse spyware or viruses & yes a lot of those system do have a unhandy program like Norton 360 installed on them.

    I run the 4870x2 & have not had any BSOD's related to the video card itself yes I have had a BSOD here & there but it was form overclocking the CPU to far EG: when I tried to push my Intel Quad core to 4.1Ghz which in this case was a issue for the CPU but is happy to run all day at 4.0Ghz but I run it at 3.9GHZ to be safe & have a stable system.

    After having owned a Nvidia gaming card & seeing BSODs pretty much daily & they were related to the Drivers I was more than happy to pawn that card off to another system I own.
  • BubbaJudge - Monday, November 24, 2008 - link

    Since the 8.10 hotfix, many of us running Vista and 4850/4870 in CF cannot run the hotfix or the 8.11s without a BSOD upon reaching the desktop. One card, no problem, two cards, infinite BSOD loops. Never mind it being just a Far Cry problem. We cannot run our machines with current AMD drivers.

    We now are at 5 pages of angry frustrated users over at the AMD forums

    Was hoping you guys would find this, I think you came very close, and am very happy to see you come down on the absurdity which is now Catalyst.

    I have been running ATI since the 9700 pro, but I've had enough of struggling with ATI multicard graphics solutions(oxymoron).
