is this microstutter?

[hash70]

hi guys,ive owned 5850cf/460sli and to be honesr ive never noticed microstutter,well on till now with my gtx480sli,the problem is with mainly cod war zombies,a few months ago i started to notice some stutter when playing zombies,if i straff round a zombie there seems to be double images down the edge of the zombie which is not there if im only useing 1 gpu,and the game feels so much smoother with 1 gpu.i can also feel some kind of stutter when i running about,my frames rates never go below 55,someone said it could be my hardrive but i moved the game from my ssd back to my samsung f3 with steam mover but i can still notice it,is this microstutter and why didnt i notice it before now?...thx

It sounds like something really isn't right there. That's not caused by microstutter, though. Sounds closer to monitor ghosting but I don't think that would happen when just using two cards. It would happen when using one, also.

it only happens when i enable sli,someone said it could be my ssd in raid,that got me thinkin as i didnt do a secure ersae when i reinstalled win7,and win7 wont give me a score on my ssd saying it can finish the test because of some problem with my ssd,but hd tune reports no problems,im really stumped over this as it was fine before or maybe i jst didnt notice it,...........................

I'm pretty sure your HDDs are fine, considering you don't get the issues with a single GPU.

Here's a post I made on another thread about microstuttering, what it looks like and how it's caused:

This video demonstrates what microstuttering is.

Basically, the gaps between rendered frames are uneven. For example, if the frames were locked at 30 per second, each frame should be output ~33ms apart (and 60fps would be ~16.5ms apart.) With multi-GPU setups though, they just aren't. This causes the video to be more juddery than it should be with the same amount of evenly-distributed frames. From what I have read, the reason is unknown why this happens (otherwise it would have been resolved?)

Some people are more sensitive to small lag spikes than others. I'm guessing I am sensitive to them as I make sure I play games at a solid 60fps and never any lower (by lowering settings, if necessary), so my eyes are used to smooth-as-butter video.

This is just what I've made out of the whole microstuttering malarkey. Don't expect what I have said to be completely factual. Hopefully it is all correct, of course.

Compare that with your stuttering experience.

update,jst upgraded froma plasma tv to 30inch dell ultrasharp,still getting the same ghosting problem when useing sli,any idea guys as this has been doing ma head for 7months now

 

[hash70]

seemed to have fixed it,used triple buffer overider/guess what no more ghosting,disable it chosting comes back /thx god

Ok but that didn't fix the 'stuttering', only the 'ghosting' right?

Is this black ops or WaW?

Black ops engine has some hideous stuttering issues which are in no way related to GPU microstutter, AFAIK tho this doesn't affect the original WaW.

its waw bud/triple buffer overider fixed the problem

After about three weeks of research I can tell you that SLI microstutter is not stutter.

When a game's load is shared between the cards there can be a microscopic delay. The end result is micro flicker. It is caused by post processing, so either lower it or turn it off.

A true stutter will go to 0 FPS. Load up FRAPS and get a recording of what is going on. (run a benchmark to text file)

This is why I keep telling people not to be fooled by benchmark results as they don't tell the whole story. FPS can be very high, doesn't mean a game is playable.

I get something like OP in L4D2 and never could get rid of it on either a 8800 GTX or a ATI 4890.When i strafe around zoey or bill or someone i get ghosting and tearing and i have tried TB Overrider and every setting you could think of and even happens on my uncles Q6600 8800GTX setup too.WAW showed V minor strafe problems and was much better than source for me.

Im tidy with my system just drivers installed everything setup perfect, windows slimmed down keyboard repeat keys turned off etc and still it bloody does it so there are just some games also that are complete dirt that will do this even with single cards.the only way to get it to stop to a point where u wont focus on it is to *cough* run windows xp and revel in the strafey smoothness and the extra 5 min fps also helps!


Here are a few tips for anyone else who cant resolve things like this

1 disable HPET in bios ( makes system have lower latency and thus smoother gameplay )
2 disable hyperthreading in bios ( eliminates stutter in BF3 )
3 lower keyboard repeat keys to zero so u have no repeat keys (showed minor improvements in L4D and stops stutter on dead island)
4 disable page file ( risky and requires 16GB ram)
5 run dpc latency checker to see if the system has lag spikes while gaming or idle
7 experiment with TB and vsync settings and pre rendered frames if using Nvidia

problem wasnt microstutter it was monitor ghosting mostly in waw but rivatuner trip[e buufer overider fixed it thank god
