what is microslutter?

Wow thanks for the article, but after reading that, it sounds like I've experienced microslutter with a single GPU rig.... Interesting.
 
I don't know about that, but I was using a single 560ti and when I entered a dungeon in Diablo 3 framerates would drop from 90's to the teens...

Was running at a resolution of 1680 x 1050. Had 16 gigs of ddr3 RAM and an i5 2500k so not sure what it was. But I guess that was microslutter.
 
Also, my monitor is a 4 to 5 year old Westinghouse 22" lcd with a resolution of 1680 x 1050. Can am older monitor actually "decrease" game performance?
 
I wouldn't call that microstutter. It was more than likely the assets of the game being loaded from your insanely slow hard drive to your system memory. If you get an ssd you will be max frame right right at entering d3.
 
Ok, old hard drive.? Wouldn't that mean that all games I play would have issue loading from hdd to memory? I'm not arguing I'm asking so I can learn.
 
Microstutter is not low fps, nor does lag have anything to do with low FPS either. I would define it as the removal of the sense of smooth motion caused by an inconsistent delivery of frames.

Some people find that a single frame above 16ms causes a stutter affect. Personally I consider that to be a low frame rate (even though its only 1 frame). Instead microstutter is caused more by the inconsistent delivery of content to the screen. It can be caused by game engines, GPUs, especially by multiple GPUs and even your monitor.

Ideally your game would render every 16ms and every frame would arrive on your screen straight away. In practice most systems have a latency of 3-10 frqmes before the picture is at displayed. But if the frames have different latencies for some reason then we perceive it as microstutter. Its every bit as bad as low frame rate but harder to fix.
 
Microstutter is the realization that the frame rate counter feels like a complete lie with a dual GPU setup. For example, 40fps on a dual card setup will feel the same as 25-30fps on a single card. And that's because the frames each card produces are not released at equal intervals. You'll end up perceiving the longer interval. But the frame rate counter will be based off the average of the two intervals.
 
And for future references.... it's microsTutter. (with t, not L).
That's why you are getting some jokes. 😉
 
It's when slutty chicks post up pics that are like 80x60 or something. The pic is just too small to fap to...f'ing teases...
 
I had dual 5870's in Crossfire, and overall had a fantastic experience with that setup. But, I would play Titan Quest (awesome game, I like it better than Diablo 3, but that's just me) and notice a lack of smoothness while my charactor would be running through the open world. If I would just watch the charactor move through the world, it just wasn't silky smooth regardless of what my framerate was. To me it wasn't a killer, not a deal breaker, I didn't really notice it unless I was looking for it... I guess I adjusted to it. That was the only game I plainly noticed it, though. It really bothers some people, others don't seem to see it at all.

I think that is just how titan's quest was animated if I remember correctly, because that's how it always was to me across multiple systems.
 
I only ever noticed it with a couple of games here and there with my old Nvidia 9800GTX+ SLI setup, not sure how prevelent it is nowadays, I hear AMD has more issues than Nvidia, especially when cards aren't identical.

The title says it all. I read people get this with multi GPU set ups. Just need educated on what it is. Thanks.

Not frame rate, not lag. It's time to display a frame changing - so if you get say 50fps you'd expect one new frame every 20ms. With microstutter you still get 50fps but one frame arrives after 10ms, the next after 30ms, the next after 8ms, the next after 32ms, etc.
 
Its also worth mentioning that microstutter is definitely not limited to dual card and above setups. Single cards such as AMD's 7970 also exhibit a small amount of it as well. The problem remains we don't yet have a good way to benchmark and measure it, frame times from Fraps are the best I know of but the approach that uses is flawed.

Nope, micro-stutter is a product of AFR. Single cards don't use AFR.

Don't mistake micro-stutter for simple fluctuations in the framerate; it's much more than that.
 
Micro-stutter is a momentary freeze in gameplay. Say you jump off a ramp with a jeep and you get a freeze while in mid air in a multi gpu config, when that freeze is up u get fast forwarded to the point where your jeep should be in the course of the jump. The game keeps going while your cards are stuck displaying the same earlier frame. I'm not sure why they call it micro-stutter, should be called something more indicative of the actual problem.

Stop posting, thx.

You only confuse the topic as the majority of your post is flawed, false and display ignorace about the topic.
