Hi all,
I haven't been to this forum for a long time (boy has it changed a lot!). Anyway, I have a question that I hope someone can help me out with.
To start with, my PC spec is a X2 3800+ with 2GB of RAM and ATI x1950Pro as GPU. On this machine, I used to be able to play high-def (1280x720 resolution) H.264-compressed .MKV (Matroska) media file on WinXP 64-bit (x64) with ease, but not on WinXP 32-bit (x86). Recently the x64 had begun having similarly low video decoding performance as the x86, that is maxing out of the CPU and thus stuttering video. After a recent reinstall of both Windows versions, I expected the x64 to regain its video decoding performance advantage but alas that was not to be. I thought the x64 had a bleeding obvious performance advantage when it comes to this but I suspect now that was because it ran the video at a lower quality setting (some videos -not all- used to smear especially if there was a lot of scrolling around) or there was a setting somewhere that took a lot of processing burden off the CPU. At any rate, I am now unable to play my high-def files and have no idea how to tweak Windows (x64 or even x86) so that it can play the files like it used to be able to. I’m tempted to hunt down a used s939 X2 4600+ just to improve my chances on successfully playing the files but it’s a silly and expensive gamble.
Any suggestions on what I can do to improve video performance? The PC was able to effortlessly decode the video so there must be some kind of settings out there that needs to be tweaked. TIA!
