First Microstuttering Test on ATI HD4870X2
@ 2008/07/14First results on finding out if the new dual GPU card from ATI has any significant issues with microstuttering brought on by the usage of more than 1 GPU. As not all frames are rendered at the same interval you might see in-game "jumps" or "stutter" when this issue pops up.
So far the HD4870X2 results are promising, but not perfect.... expect a full test to appear on the web in the coming days. Here's a preview snagged from XS.org

Ok, I found a new game where 3870 X2 shows very bad microstuttering and it is Race Driver: GRID. I was checking my benchmark results for R700 preview I'm working on and noticed avg FPS was very bad with 3870 X2. So I immediately applied my previous testing methods using Fraps to log frametimes and analyzed results with Excel: 3870 X2 shows similar behavior in Race Driver: GRID than I noticed in Crysis but it seems to be even worse. In Crysis 3870 X2 rendered every other frame after ~21,5 ms and every other after ~49,5 ms. In Race Driver: GRID 3870 X2 rendered every other frame after ~24,9..27 ms and every other frame after ~40,2..42,4 ms. I repeated the test with R700 and it showed again very stable rendering times between every frame: ~15,3 - 17,6 ms. |
