Or let me know the exact release name and at which times-stamp it happens and I download it. Yes, legal over here. Also a classic is the power management of a GPU. In most cases it is responsible for micro stuttering. A GPU tries to clock down it's clock rate once in a while to a configured minimum. Then it detects that this doesn't work out and goes back to the old clock rate right away (or after a couple of frames). But such stuff usually comes in fixed intervals and not always at the same time in a file. Both ATI and Nvidia are too agressive here for some better review results in regards to power consumptions. The faster the card is the more likely you experience such problems as the GPU is more or less idle. Usually this happens every 5-10 minutes. Also it plays a vital role if you decode audio in your PC or if you bitstream. Because when audio is decoded inside Windows anyplayer is more sensitive to the reference clocks whereas bitstreaming is just passing through stuff. Applies to HDMI especially! You won't see such things in any stat renderer. But having something like GPU-Z running will show you the dropping clock rate. Compare these with playback in other players. Is there a difference? Bingo! Fixing such problems is easy: just configure your GPU so that the clock rate doesn't go too low. This has no impact on load or temperature only power consumption. Just increase it for testing. Check any over clocking guide how to adjust stuff for your GPU. You don't have to go higher. Just increase the minimum level. And if you don't care for a little power consumption don't let it clock down at all. As said no influence on temperature or load. For any gaming or media box it's essential not to clock down the GPU during playback or gaming. In any such installation I set the minimum clock rate to the maximum of the GPUs default configuration (not talking overclocking here). A simpler slider in most tools like Afterburner/RivaTuner or whatever (you can of course use profiles). So give this one a try. GPUs are more complex than CPUs these days and manufactures are too agressive with their power management. It's even worth on mobile GPUs than Desktop GPUs because they try to clock them down even more agressive. But first check if it happens always on the same file on the same position. If it happens in more or less fixed intervals instead then ny bet is on GPU down clocking. And the GPU is the reference clock for media playback.</blockquote>
