HD5970 Microstuttering tests

[eRazorzEDGE]

Well, this is no definitive review, but I just completed a couple runs on my system... and learned how to use spreadsheets and how to use formulas in said spreadsheets. So here's the details:

Crysis 64bit DX10 1920x1200 4xAA running on an AMD X4 965 @ 4.4GHz Core, 2.88GHz NB, 2.88 GHz HTT Link, 1600MHz DDR3 RAM. I have two ATI 5870's at 950/1250. I'm running Windows 7 64bit.

I ran the Crysis benchmark tool for 3 loops in one run, for both Dual card and Single card setups. I set FRAPS to capture the frame times and stop after 10 seconds of recording. I started recording the frame times on the 3RD loop right when the black truck exits the scene (the camera moves past it) to the right. This is to hopefully be as repeatable a test as possible.

Dual Card setup...

This one is with the Default ATI driver Supertiling technique:



This one is with the AFR technique:



and the very much needed control setup... Single card...




OMGWTFBBQ?!?!

Could it be there is the same damned thing happening on a single card as a dual card? Could it be that everyone is a little more influenced by what others tell them then by what they can actually prove?

On a side note, if this variation in frame output from one frame to the next is responsible for the so-called microstutter, then that would mean everyone on here can see the difference from one frame to the next while being shot at with 30-60 frames per second. For a test on that, in the span of ONE second, count from 1 to 60 and tell me how you do.
