Define Micro Stutter  

post #1 of 60
Thread Starter 
For some reason I had micro stutter on a system i was putting together. However a bunch of OCN users claim that its NOT micro stutter and I have no clue what im talking about.. They dont say what it is or how to fix it, 1,000 rep trolls. So im askin for helpful intelligent people to come foward.

In Mafia 2, it was around intense graphics and explosions. You would notice it mostly inside buildings where there are a lot of textures. You would turn, and it would shutter choppy type stutter as you rotate.

Ohh I forgot, also in Crysis 2. The very beggining where the fires are near your very first enemy encounter. I would sidestep around the fire and get it.

My brother came over and said, "your new computer is still choppy like that?"

I was pretty embarassed to say I got this great quad core cpu, ram and motherboard, and games are still choppy because my SLI 8800gt's cant perform?

They can perform. I ran crysis one just fine on my socket 939.

Heres a great article on micro stutter.

http://www.pcgameshardware.com/aid,6...gies/Practice/

Here is a video of micro stutter on a very high end system. SOme say it happens at 20fps or low end systems

http://www.youtube.com/watch?v=-ZP_P...eature=related

Those cards can handle the game easy. That is a perfect example of micro stutter and its effect on all systems high end and low end. Its not worth the headache once you get it, trust me.

LOL...another thread you need to go get called out and myth-busted on?

The only part of your OP i agree with is the, "I have no clue what i'm talking about" part. Because you don't.

What you describe also happens with just single cards, and had nothing to do with what appears to be 'microstutter.'

brettjv already provided some actual empirical evidence for identifying and isolating cases of microstutter, and you attempt to refute it by posting videos of this phenomenon you're seeing as experienced by other users subjectively via YouTube.

Again, what you're describing as 'microstutter,' also going off from the previous thread where you get a frame 'popping'-like effect, is not technically microstutter caused by SLI; that's more like a system bottleneck, as the same thing happens without SLI. It can happen in areas that have a lot of things that all of a sudden need to be rendered, sudden movements, etc. Those aren't SLI-specific symptoms, i'm sorry to tell you. I've had 7 different SLi/CF setups, so I know a little about what i'm describing here.

I have no idea how you formulate this claim that SLI as a whole is useless and broken when you base that claim on having only a pair of 8800 GTs, which were arguably cards that existed during SLI's initial mainstream rollout.

Drivers then were definitely not mature with regard to SLI, but it's no longer an issue as of the last, what, 3 years?

You, sir, just need to know when you're wrong and admit defeat, before you again resort to name calling, meme-using and general ass-hattery (like making entirely new threads about the same subject you were just proven wrong on).

Ridiculous, but i'll leave the rest to brettjv.

lol, the you tube video is NOT micro studder. its the POS engine that NWN2 uses, its horrible. you set the max on max details and high AA you will get choppiness becuase it draws shadows for the full map which kills the performance.

the reason why you have frame rate issues is because your 8800GT is old and only has 512MB of ram. crysis 2 is a new game. your gpus are 4-5 years old.

even when crysis 1 came out, sli'ed 8800GTs could only pull like 20-30 fps tops.

what you need to do is turn down the gfx details for a smoother game play experience.

Microstuttering is a phenomenon. Sometimes phenomena cannot be explained.

lol, you make it sound as if microstuddering is a "unsolved mystery". no its not. it happens on multi gpu setups that are using poor drivers.

OP is not experiencing micro studdering, just frame rate drops, due to moments in game where there are rapid texture fills like explosions and fire.

If you came here to insult and be incorrect you will also get reported and asked to leave.

Sorry I didnt include it in my original post.

When using SLI I would receive the stutter, when using a single card I would not. In all of the following games:

TF2
Crysis 2
Mafia 2
Guild Wars
America's Army 3
Empire Total War
Dragon Age one and two

Most noticeable were Mafia 2, Guild wars and America's Army 3. AA3 was terrrrible stutter at 80-110 fps. I tried to force alternate render 1 & 2and it dropped to 30-40 fps. I then ran a single card and it was smooth as can be, 50-70fps.

Well I can find better videos on youtube? I had the same issue, and my cards are getting well over 40-60fps.

I didnt mention I just ran these 2 cards in my system a week ago and had no issue with my socket 939. I went to a i7 920 setup and have the stutter. So I dont think its a lack of performance issue. I think its more of a latency issue with the motherboard or ram. Im not sure. I also considered the triple channel ddr3 vs the 8800gt memory. I did set the games to optimal graphics settings and even lowest. I even tried 800x600 res

Ill update my sig, that was my old system that ran every game 100% smooth on sli. I was hoping to bring my cards over to my new mobo/cpu setup, however micro stutter, or what every claims is a bottleneck is plagued my system

+1 rep for being accurate about the texture fills and explosions. I said that exact thing in another thread, however I got flaimed for saying such happens.

In mafia 2, if I enable physx and wore the leather jacket, it would move when I ran, and indoors it would stutter so bad with all the textures. I got a 8600gt and ran that as a dedicated physx, no luck, even set cpu to physx. 1 card ran it perfect, 2 always stutters.

I might sli my system to benchmark screenshot and video my stutter issue. any suggestions to fix it would be great

PS you mention drivers, and that was the one thing I didnt experiment with much. I had to update my drivers when installing the new mobo and you may be on to something. thanks again

Here is the interesting discussion on topic I read recently. There is even a video shot @ 300 FPS for what it worth. From my personal experience, its there, but you might not even realize that. I just switched from GTX 460 SLI to a single GTX 580, and immediately noticed how much everything is smoother with single GPU. And if you'd ask me 1 week ago "do you have microstuttering", I'd honestly would have said "no, everything is smooth."
post #8 of 60
What you are describing is your is CPU and bus bottle-neck.

Your GPUs are hungry for data, and the CPU/HDD/BUS/Memory do not provide the data fast enough.

This causes your GPUs to wait for data (hence the "freezing" feeling), and when the data comes in a burst, the GPU is pushing the frames out as fast as it can to satisfy the FPS requirement, so you feel a "rush" feeling of frames.

This is not micro-stutter. That is a whole different thing.
micro-stutter feels like everything runs in the speed it should, but its just not-smooth.

My FPS drops down whenever there's a lot of textures being processed on high settings in Metro 2033, but it handles Counter Strike 1.6 without problems.

Am I suffering from microstutter as well?

rofl, metro 2033 is way more gpu intensive than a game based off an engine that is 8 years old, of course the frame rates are going to be silky smooth in CS1.6 on your gtx460.

also, the polygon count in metro2033>>>CS1.6
