2x 295 micro Stutter

[Tony2438]

Dose any one know how two 295 with one of the GPU dedicated too physicX? is there still a problem with the micro stutter?

i think the 295's themselves cause microstutter so yer you would get it but maybe not as much if you are quad SLI'in them

Microstutter only happens at very low framerates, below the vsync level. So, unless you're running a game that even an uber system with 2 295s can't render quickly, you won't have a problem.

If the system has plenty of rendering headroom power and can manage a solid vsync-locked framerate then microstutter won't happen.

Did i read somewhere that you got stutter with the quad sli set up due to it been an sli'd card in sli.

To explain that better, you have the two pcb's in the card in sli, then you have the main sli bridge connecting the two graphics cards. I hope that made sense.

Do the same things happen on the newer dual GPU on one PCB cards ?

The new 295 has identical performance to the old dual PCB type. There is no difference from a user's perspective. They new type are simply cheaper to make. You can even mix old and new in the same PC.

Hence, any problems the old design had, the new one will too.

so how come things in vantage stutter e.g the cloth covering the boat/jet that stutters and also as she is taking off it stutters then,i doubt that would be at a low frame rate?

Vantage always stutters for me, no matter what card(s) I stick in there.

In fact, I believe all the futuremark stuff does at some point. I've always put it down to it pushing the hardware, nature of the beast.

Real gameplay's never an issue tho.

Who invented this term "microstutter" anyway ? Sounds stupid.

i just said it ant be due to the framerates man,i heard the phrase from trubritar

Ah, it's a casual comment m8, nothing intended

Vantage or any FutureMark test will tend to stutter because it's pushing the PC hard and the framerate is low - certainly lower than the vsync rate of at least 60Hz.

If I remember correctly, it shows the realtime framerate within the benchmark. If not, just get Fraps and that will give you a realtime framerate display.

Get it from fraps.com

no no quarms dude thats just were i heard it i actualy thought it was the correect phrase,i have fraps i dident no the FPS were diffrent so that would be good to check out,but ime shure my setip with a 260 never stutterd onebit it slowed down yer but never messed up so to speak

The Futuremark tests tend to show you an FPS built into the window.

Cheers - it's been a while since I played with them.

Here's a good explanation of what microstuttering is, with graphs and all.

There's microstuttering and there's stuttering... For "micro" a few things you can try... switch from AFR to SFR by modifying the profiles, or change the number of pre-rendered frames from the default. AFR with VSync enabled works better, but I don't think you got TWO GTX295s to play with VSync enabled...
