SLI/CF is microstutter an issue for you?

The stutter is affecting your benchmark performance/scores? Sounds like something else is a bit suspect too.

I have a free pass from the Mrs tonight so I'll add it to my to do list which includes all kinds of interesting stuff :D.

Tell a lie with regards to the stutter, I had it in TR but I was on pre TR release drivers. Updating solved it. Assuming you've tried all kinds of drivers already by the sounds of it?

I can only imagine how irritating it must be....

One thing I can think of to hand, again which you've probably tried already, have you put the cards at the same clock speed?

Yep. Firestrike i get high 9K - low 10K:

All over the shop.

My GPU Usage on the second test. Highest of 81% lowest of 62%.... You can see the usage of the first test, 95-99%.

and Unigine 4.0 i get 1600 @ 1150/1700

If you can do that for me, that'd be great. Who knows, could be X79 related?
 
I had bad microsutter with my old 690 if you have a i7 setup try unparking your cpus there is a program that does it for you,i did this and bf3 played smooth as silk after.

Farcry 3 is a game issue to be honest. Not sure there is much either side can do with this.

Agreed if radeonpro or NVidia inspector can't fix it, then it must be a game issue. Mind you it seems to run well on the new quadro drivers, maybe I should do some frame latency tests, but I'm lazy and I'm currently on anti-biotics for an ear infection and all I want to do is sleep :D

I don't believe it is though. I had complete smooth gameplay regardless of frame returns with 313.95 drivers. I would have agreed prior to installing those but they proved it can be very smooth with all the trimmings.
 
I had serious micro-stutter problems back in 2009 when I ran on a X58 platform with Ci7 920 and GTX 280 SLi. Changed to AMD nVidia NF980a chipset and Phenom II X4 955 and the stutter was almost as good as gone. Adding a 3rd GTX 280 actually reduced the microstutter compared to two cards.
Last year when I had a GTX 670 RMA and just ran GTX 670 SLi I had a bit stutter but not much, but upon getting the new RMA replacement and going 3 cards again the micro-stutter was reduced yet again.

It happens that micros-stutter appear in some games, but generally I hardly notice it since, it's quickly gone again.

I'll try to do a quick run of Homefront tonight to test it out.


NB... I recall this old test from TomsHw.

Three- And Four-Way CrossFire

The performance of three- and four-way CrossFire setups not only surprised us, but also managed to utterly convince us that micro-stuttering doesn't have to affect your multi-GPU configuration. For some reason, the third GPU almost always eliminates micro stuttering and has a less-pronounced effect on performance. At least in the games we ran, the fourth GPU is more eye candy than anything, and its contribution is minimal.

It was an issue for me, had 2x 7970's, sold one now and just run one to get away from Microstutter, and in some games the performance was worse with two cards..

For reference to the post above, I am on X58 still, so that could be part of the issue!
 
Very interested in this thread, thanks OP. Some people don't seem to notice microstutter but it's the number one thing that's kept me away from Xfire so far. Will monitor.

There you go Greg, just buy another titan and you're golden! :D

Personally, I haven't noticed any micro stuttering with my 680s but I'm interested to know if its there at all. Will run some tests tonight and post the results.
 
I blame LtMatt. I didn't till trying that bench viewer. To be fair, it was only with the 310.xx drivers that I noticed it and with all of the 310.xx variants.

3/4 way setups when properly setup tend to reduce or eliminate microstutter due to another component other than the GPU sub-system being the bottleneck so GPU output uniformity tends to be externally regulated. I'm not sure what that does for input latency tho I'd imagine in some scenarios it would be quite noticeable.
 
One game where this is a real problem for me and this is Far Cry 3.

Engine related, does not seem to be driver related as it affects both manufacturers.
 
A few more for those interested, all using 314.07 driver as the latest beta only works well for Tomb Raider. Crysis 3 in unplayable using 314.21.

Hi Rossi,

Just ran Firestrike at my very considerate clocks of 1100/1500 and CPU clocked to 4.4 GHz and got 10k. No real noticeable stutter but I did forget to do frametimes and it takes ages to run it!

13319 GPU
11702 CPU
3300 Combined

Got Heaven 4.0 as well. Full 90-99% usage on both GPUs. Score of 1800 @ 1100/1500. Here's the frame time results:

Here's my results for 2x 680s with driver version 314.07. 1080p with all settings on ultra with 4x MSAA and vsync off.

I also had a play about with vsync and this is BF3 with vsync on (smooth) and tripple buffering
