Micro-stuttering/incorrect frame rate with 6990?

post #1 of 38
Thread Starter 
Hello, I'm having some really frustrating issues with this card.

I'll use Crysis as an example.

I'll run Fraps, and it will tell me I'm getting around 30FPS, when the game feels like it's running 10 FPS. I think this is the same type of micro-stuttering you get with SLI/Crossfire systems. Only thing is, even when I have my fan at 100%, it only gets up to around 59C while gaming. Basically, all my games are unplayable.

I know I'm probably bottlenecking the card with my current CPU (Phenom 2 X6 @ 3.3GHz), but I think the issue is stuttering. I'll deal with the bottleneck some other time down the line.

I've given it a fresh install of windows, disabling/enabling many things in CCC, and turning the fans up to 100% while gaming. All with the same results. One things that did slightly improve things though: the 6990 seems to have a "BIOS switch" right next to the Crossfire bridge. I turned that switch to the "Performance" setting, and it made the game feel more like a 15FPS. But none the less, this card is more than able to plow through games at higher frames. I've recently set the card back to the default switch, since I don't like the risk of the warranty voiding.

I am completely at a loss. I've got about a day left to be able to make the decision to return all my recently purchased parts and save my self from having an awesome video card that I'll never be able to use unless I buy a really expensive CPU. Sorry to sound like a rush, but this past week and a half has been nothing but frustration.

I need one of these.

I feel this is more of a driver issue rather than a bottlenecking issue. I've often experienced similar problems like this when I first purchased my 4870X2. The performance of most games were terrible on all related levels and I'm sure I wasn't using even 10% of the potential power of my card. Later releases of the drivers seemed to solve that problem.

I don't know if you've tried this already, but I've often seen performance jumps when I used to toggle my Catalyst AI On or Off. Try messing around with drivers a bit more or looking for recent hotfixes from ATI and maybe that problem can be solved.

Hope that was helpful.

I've done quite a bit of tweaking, so I'm not sure at this point.

I've looked, but I don't know if ATI has give any 6990 support other than the 11.4 drivers. Thanks though, but I think im going to wrap this all up and consider this past week the biggest waste of time in my life.

This is called crossfire, FRAPS will tell you 50fps or 60fps or whatever, but in reality gameplay feels like crap.

My last(EVER!) CF setup were dual 5870's and Crysis felt like crap. Not only i've had the same issue you're talking about, i also experienced texture blinkering(sky mostly) and occasiaonal texture missing(trees)...

How disappointing. I remember SLI being a pain in the ass, but it wasn't that bad. Wow, higher end gets worse.

I'd love to get the fastest Single GPU card, but I cant run Eyefinity/Surround with the same performance as say, a 5970 without having to SLI two GTX 580.

Some people are more sensitive to microstutter than others. Drivers can help make microstutter symptoms better. CF and SLI both have this issue.

Since you are unhappy, you should just get the fastest single GPU card.

You're very polite on this one. Some people just can't admit it to themselves that their expensive setup sucks, others just do benchmarking and no real gaming, and some just need to get their eyes fixed.
Also, there're huge group of "theorists" who only read reviews and speculate on message boards.

I'd love to get my self a GTX 580 (best single GPU card atm), but I cannot setup Nvidia Surround on one card. I could need to get an SLI mobo, and a second video card, wich would be a waste of money that I really don't want to dish out.

I wouldn't do that if I where you. RMA'ing will just be a waste of your time. The issue seems to be either improper advertising of the minimum requirements, or bad driver support.


So if anyone can suggest something else, I would really like to hear it. But besides, OC'ing, disabling all power settings, giving a fresh Windows 7 install, reinstalling the drivers dozons of times, and even going through AMD/MSI tech support (which just gave advice to do everything I have already done), I don't know what else there is to do except wait for a driver update from AMD. And maybe even then, it may not work.

Completely at a loss...

Microsuttering is also present with single-gpu solutions, although to a lesser degree
Also, it ain't about being polite or not: microstuttering is something that is there, but not everybody notices it. For example, I just hate Vsync because I can't stand the lag it adds...but plenty of people uses it every day and has yet to find a problem. My point being: some people is more "delicate" than others, and also you get used to stuff. Try to play with a 100hz CRT for a few weeks and then play with a normal TFT, for example ^^
