GPU Mist microstutter analysis tool

[Gregster]

Just thought I would put this info out, as it seems a pretty dent little tool that measures microstutter. I have had a little play with it but still working out what is what, so will come back to this thread a bit later when I am more clued up.

Download it from here

Use FRAPS to measure your game and tick the box that has frametimes monitoring. Run your game, run the bench and see what is what

This was mine from COD: AW

Thoughts?

^^ FRAPs (same with any other software tool that doesn't have access to hardware debugging on a dev board) can't show an entirely accurate picture but its close enough to give a rough idea for comparison purposes.

PCPer was using hardware capture so as to analyse what level of microstutter was actually being shown onscreen whereas FRAPs can only see what was sent to be displayed onscreen but not any delays that might happen between the frame being dispatched and actually appearing onscreen. (Which doesn't take into account things like nVidia's hardware smoothing).

Yer, it certainly isn't anything like FCAT and can only read what goes to the GPU and not the screen. I will have a play some more and see if it picks up any stuttering.

I would certainly be wary of using FRAP's numbers as the be all and end all to judge it by but for approximate comparisons or to look for issues that would merit a deeper look it can be useful.

What I find it most useful for though is getting a real picture of the minimum frame rate situations as a single figure never does this justice and the consistency of frame rates around 60fps as both of these are far more meaningful on the quality of experience than a single minimum fps number or min/avg/max numbers.

Agreed. Fraps was the go to tool and this is the same thing with a different readout but it isn't a patch on FCAT. I remember the thing with Crossfire kicking off and FCAT was showing runt frames, which FRAPS was missing.
