How bad is micro studering?

[cburke82]

Im new to this. But thinking to the future would like to add another 6950 to the mix. So what sort of issues can I expect and how bad will the MS be in most games?

 

[jjb8675309]

yeah I do notice some "microstutter" while using 6879 crossfire in BFBC2m but I think its mainly due to bogged down servers

Surely that would be 'Ping lag' not microstutter? What about single player mode?

 

[jjb8675309]

yeah its no doubt ping lag as the single player is fine, furthermore these cards are supposed to scale well and I usually get around the performance of a 5970 since my cpu is only a p2 955 @ 4.0ghz, but my point is just that microstutter can be mis-diagnosed when the cause it actual other contributing factors

That's what I was alluding to before when I said the jury was still out, from my own experiments over the years I think it's the CPU's that are used but that doesn't mean that they are bad CPU's, just not the right ones for a particular set of cards.

^exactly, Im on board with that

well maybe in COD 4 but the majority of newer games will struggle to keep minimums and even averages above 120fps. nope wrong maybe in a dx9 game your doing that but not in crysis, metro, BFBC2, just cause, alien v predator, crysis 2.... etc my 2 6870s are better than a single 580, that doesnt mean im going to vsync 120 hz bc I can't maintain 120 fps in most games, not even close to it, and there is no way your doing it either even with (dual 6970) basically a 6990s power... its not going to happen, maybe in a few games but other than that you have no clue what you are talking about, people do not game on a pc at 120hz because it makes the response time super slow, not to mention that its not practical because you will not produce 120 fps consistently not to even start talking about fps minimums, trust me people are still using 60hz, and do not recomend the op get a 120hz monitor for gaming because it makes no sense.

but we ain't talking about two 6870s. We are talking about 2 x 6970 that can run 1600p without effort. Now what you think its going to do to the fps in 1080p. And you mention 4 games out of hundreds. BC2 is a game that's got bad coding and is cpu intensive especially online. Crysis got a huge sound engine in its game engine which your cpu must do. So that don't mean much. Then there's the 60mhz vsync issue where your fps goes half the refresh rate adding more graphic detail just knocks it down down down. that's why probably you don't get much fps with your two gpus because you got to hold them back running under 60fps where you couldve hold them back running under 120.
Btw Crysis use motion blur that you see in the movies that runs 24fps that's why 35fps look so smooth on it.

I'm still trying to work out what this has to do with so called 'microstutter'.

the OP already got a 6970 and want to upgrade to a 6970 Crossfire setup. That's the question in the opening thread. Now you think adding another gpu when the OP already can max out games on the current resolution will add any benefit?
Micro stutter happens btw running high resolutions with a slow disk setup.

I think so called 'microstutter' is caused by lack of onboard cache from what I've seen.

I would like to get my hands on one of those sweet 10mb HDD's from your signature lol But really tho your saying if later on I go with crossfire and have a slow HDD thats where the micro studdering comes in? Would that mean I should upgrade to a 6 gb/s HDD or SSD at the same time?

nope. The gpu uses its own ram as the buffers.
Problem is the game only loads bit for bit in the ram. Now when the data goes to the cpu and then offloaded to the gpu it has to wait. Now at high resolutions and the game is optimize to only load bit for bit in the ram the swapping between the ram and the hdd will make the gpu wait.

That's your theory and I have mine.

lol. The micro stutter was ages ago and with some games. Especially if they don't load enough data in the ram. Some games you can edit the ini files to configure that. But that's not really a issue these days. But having a ssd won't be a bad choice but if its not in your budget then you don't have to worry about it. You can always do a cheap raid with your current disk setup

nope 2 6970s are not handling 1600p at 120 fps, that performance will look terrible from the constant frame drops they will have. BF is far from poorly coded, just a lot going on with there physics engine which is run off the cpu, etc, not following your logic here so I will agree to disagree, and I still have not seen any true gamer using 120 hz so...

Me too.

 

[ubercake]

yeah resolution should have nothing to do with microstutter imo

Agreed.

 

[cburke82]

if you cant find vsync, please go buy a ps3 and play that, pc gaming is way beyond you.

If there is a problem with CCC where the tab is not there I dont think you could find it yourself. I build my system by myself and have OC my CPU flashed my GPU and it is all working fine except for the CCC problem. I think PC Gaming is not at all beyond me LMAO. I have talked with amd and they will only tell me to do a fresh install of windows. I have all the right drivers and C++ installs and the most up to date .net framwork. I think you should look at the whole picture befor you make comments like that lol.

@Lui Kang

huh, what why the hell would you want a raid configuration for the OP ?

the best answer imo has very little to do with the discussion

 

[ubercake]

Good luck to OP if that's the choice for best answer.

 

[cburke82]

just picked something so the thred showed as solved as the topic was slowly drifting to something not related to the question asked lol

 

[ubercake]

Ah. OK. It did get a little crazy there.

seeing as you never addressed the question any thoughts on the microstudder issue. How is it with the SLI you got?

It is absolutely non-existent. I run one 1080p 60Hz monitor with everything maxed and I mean everything (AA/AF/AA tranparency/tessellation). My framerates are often triple or more than the Hz my monitor has to offer. I've never had a need to turn on vsync.

Cool I hope the same goes for me when I get a second 6950. However I have a 42" LCD at 60hz I seem to get tearing with vsync off even when the frame rates are less than 60 lol. Maybe its not tearing? I get a semi transparent line going from the bottom of my screen to the top every 20-40 seconds with it off. I can play with it but if my screen wont do more than 60 FPS anyway I dont see a need to have more FPS. However when I play Crysis for some reason it will at times lock my frame rates at 50 or some times 25 lol I have a 6950 and it will cruze along at 60 ish and then BAM lock at 25 FPS for no reason.

 

[jjb8675309]

I feel like I am continually having a studdering problem with my 6870 crossfire, and now I am wondering if it is becauseI only have 4 gigs of ram or bc my 7200 rpm HDD is holding me back... any thoughts or is it just poor drivers? I am running 11.2 and the problem I am expririencing is just studdering in places where there is evidently some scene loading going on like in batman aa or when I open a door, or in bulletstorm with a lot of stuff goign on I get this slowdown/ studder, otherwise my frames are locked at 60 fps with vsync, from what I gather on this thread I cannot really tell why I don't have flawless performance and its starting to make me mad... the avg frames from crossfire are higher but it seems like my mimimums are worse, maybe im just bitching but when I spent over 400 on gpus it is a shame they dont work as advertised, im about ready to sell both and get a single gtx 580, does anyone have any thoughts?
