I just noticed the strangest thing. The gpu has taken one gb from the ram, so the gfx now has over 1900mb. This seems unneccesary, but I can't find anywhere to change it. The only thing I found close to it was some pci-e option I don't remember the name of, something with "payload", set at 4096mb, which I changed to 128mb (the smallest possible), but nothing changed.
By the way, I've now tried mpc-hc, and it's amazing. I fiddle around with a lot of different codec packs (coreavc, vista codec pack, cccp etc) and ac3filter, but in the end, it seems as if just the mpc-hc (x64) can run anything on it's own, and the cpu load rarely even surpasses 30%, even in 1080p. Although, even when the cpu never gets fully occupied, there is still some slowdowns, or jagging of the image (audio is always kept synched (without the option)). Is it the video, or can you do something about it?
Ok, being a slow thinker as I am, I just realized this slowdown in HD movies and regular SD videos is the same - not caused by underperforming hardware. I do think it has got to do with the data stream, althought not directly by the harddrive, as it is a new SATA disk from samsung. Can it be the motherboard, or it's disk drivers? Maybe it's the memory as there already something fishy with it? It scores quite low in the vista benchmark (memory operations), 4,0 (the computer I am sitting on right now has memory at the same speed but with higher latency, and it gets 4,5 (a64 3200+)), and sometime ago it underperformed greatly in comparison with similar memory in the SiS Sandra bench. Might this also be the motherboard or it's software? Anyone find this familiar?
