Beginning to hate my rig -- microstutter!

here some food for thought. instead of acceleration (which is not uniform). these registry edit will scale the current mouse dpi. use at your own risk. not affiliated with author.

You know the OP has your mouse right?

I do now. Must have overlooked that detail.

My other suggestions still might help, given a single card or framerate lock works fine, but I don't have much experience with multi-GPU setups.

 

[tweakboy]

Do a mb BIOS flash. That should fix it.

System-Wide Windows 8.1 Mouse Fix

 

[apoe]

yes. a little. ignorance is bliss.
that mouse stutter was always there. just never paid much attention to it.

anyway. microsoft mouse 4000 properties does not have much to tweak.
turn off "enhance pointer precision" and that reduced the mouse drag length by ~50% on the desktop (feels like old ball mouse is back and now have to lift the mouse 2.5 times vs 1 time to drag across surround) and that also reduced pointer speed a little. next - increased the pointer speed up a notch. now pointer speed is almost back to normal. hopefully this will be the new normal.

in game (bf4). panning was not perfect (compare to keyboard) but much much smoother than before.

my $2 says that the mouse tracking input gets amplified/accelerated by windows which adds noise. that noise shows up in game as mouse stutter. this is one of those "i am dump so be smart for me" features. hate these type of features. some of us are capable of making decision for ourselves.

if one desire better mouse tracking. buy a better mouse. not stupid software acceleration bandage. (have a reason to spend $$$ for a gaming mouse now - )

google enhance pointer precision agrees.

your mileage may vary.

His issue is not mouse acceleration at all.

And yes, 'enhance pointer precision' is accel, I thought this was common knowledge. The only Windows mouse setting that is 1:1 input is the default middle setting (6/11), otherwise it skips mouse inputs to make the movement slower or skips pixels to make the movement faster.

In BF4 with raw input enabled, the game polls from the mouse instead of going through Windows, so those settings should have no effect in that game.

MarkC mouse fix only affects super old games like original CS. For newer games and Windows in general it does nothing over just unticking 'enhance pointer precision'.

 

[UaVaj]

you are wrong regarding bf4.

(1) disabling "enhanced pointer precision" did improve mouse panning in bf4.
(2) enabling markc's 1:1 was a worst than stutter (was like frame dipping/skipping). had to revert back.

whatever the issue is. this mouse input is definitely causing some stutter (at least with bf4).

I wrote a reply a few hours ago and i guess it didn't go thruh.

Lava i also have 780Ti sli rig and i have not had the issues you are having. Both my Ti are ref designs by MSI. The current games i play are Tomb Raider 2013, BF4 and COD Ghost. If i had

Ghost was the only game giving issues( i got that sorted out), but i guess is because it is just badly ported to PC.

Best of luck sir.

 

[Deders]

Loads of people have had issues with ghosts, it's not an SLI issue.

Yeah, believe or not you actually have to turn certain things on and off to make run good. Like distortion has to be on, and depth of field has to be on too.

:thumbsdown:


Sorry for going off topic.

Thanks for that. I'm not finding the registry edit instructions. I don't know where step 4 is.

 

[sxr7171]

Sorry I see it now. There's a plus button.

 

[lavaheadache]

SO just as a follow up. I just got my hands on a Dell ps/2 mouse and guess what? Nothing changed.

Oh well, was a nice theory though

Are you willing to try and see if you can see anything with debugging tools?

Obviously game developers have stack tracers graphs and stuff, but I'm more thinking of the System Internals (http://technet.microsoft.com/en-gb/sysinternals/bb545021.aspx) stuff specifically Process Explorer. Not as easy to use as glancing at task manager or afterburner graphs, but it does have a lot of information. Problem is a lot of potential CPU hogs are services and those are harder to see what's going on as Windows tends to dump a whole bunch under into one svchost.exe process.

There should be some tutorials from the author, Mark Russinovich, on Youtube but they are mostly aimed at malware removal.

Would be a lot of work of course and no guarantee that it will work, but at least your problem seems to repeatable which makes it a good candidate for this kind of stuff.

 

[BrightCandle]

You have me stumped lava. On the one hand microstutter due to the GPUs should definitely manifest on a controller and other inputs, but equally it does seem unlike its a Mouse issue. I think I am out of reasons.

Can you try without SLI, if that still shows the problem that will at least eliminate the GPUs being the problem, but it won't find the underlying cause.

without SLi I have no issues............

That's not to say I can't enjoy gaming with SLi. I just have to run a frame cap, like what I had to do with my 7970 crossfire setup a couple years back.

I really thought that ps/2 mouse was gonna do the trick

I'm beginning to think it's a MST issue more than anything

 

[Puffnstuff]

Have you tried another sli bridge? Once upon a time I had massive issues and it turned out to be the bridge I was using. Replaced it and things were normal.

Could be.

I've had no issues with SLI on my 2560x1600 display. I'm no stranger to microstutter either as my pair of 7970s definitely exhibited it (before the frame pacing update anyway). When I was watching PCPer play some games @ 4K on the ASUS PQ321Q with SLI Titans I noticed the dreaded microstutter when they launched Crysis 3. That is what put me off from going 4K. I'm going to wait until non MST displays come out.

Wow, I have never seen micro-stutter before, but OPs video was a great representation of it. I run almost all Nv cards and never in SLI, so it's one issue I have never encountered. Just this weekend I repaired an overheating 4870x2, so I guess I can join the micro-stutter club if I really want to.

Sorry to hear you are having to deal with that, Lava. Hopefully with enough patience and a little bit of luck someone can hit on the proper workaround for your setup.

I'm not gonna sweat it too much. I'm gonna get rid of a card this week I think. One of my friends who has my other 4k wants to step his 780 up to a Ti so I'm probably gonna hook him up. Also I just ordered a 290x off the egg a couple days ago for $549, so I'm gonna try out the red team too.

Something tells me that my 290x is gonna have a hard time taking down a Ti @ 1250mhz(stock voltage)/7800 mem.

 

[BrightCandle]

Yes it really could be an MST issue. I think MST is a really bad idea generally, just seems like a horrible hack to work around issues with monitor controllers and I am convinced that the future of 4k is without it.

Try contacting Ryan and pcper.com. He loves this sort of problem and if he can reproduce it he will kick Nvidia in the nutts repeatedly on your behalf until they fix it.

My personaly experience of living on the bleeding edge with eyefinity/surround/144hz etc has all ended up bloody. Nice when it works, horrid when it doesn't. Its sad to hear that 4k has issues but I am not surprised actually. Do try Ryan and see if he can reproduce it, microstutter and its problems are a bit of a love for him and if it can be sorted he will get it done for you.

Yeah a 290X is a bit below the Ti.

But you do get that extra gig of vram. And @ 4K i bet you will need it.

You found a 290x for $550 on newegg?!?!?!? What?

 

[Puffnstuff]

I had microstutter with my 480's playing bf3 and it would rear its head at the most inconvenient times. When the environment froze for just that instant during run and gun I was vulnerable. This is why I chose to replace them with a 780ti so I would only have one card. Yes in the back of my mind I know that somewhere down the road I would probably add another one but not yet.

 

[UaVaj]

any update on the 290x cross fire?
