well what does that tell you? It tells me you have an I/O bottleneck that he does not since x264 is so CPU heavy any I/O throughput problem is masked. This why i want the baseline with just
MPEG2Source("E:\Recordings\test.d2v")
(No encoding just that to test throughput)
because any decent box can read 40 frames a second in but when you get up to 400 FPS well.... that is a lot of data.
You may have a driver installed he does not that is slowing you down. A good example is most all anti virus. The default is for them to scan a file on OPEN READ WRITE and CLOSE. this will slow you way down and you should only need to scan once on OPEN and once on CLOSE. if you let it scan during read/write your I/O will be cut in half or more.
no need to wait for your friend if you make a ram disk and test from that. (note if you can't get at least 1 gig second read from ramdisk your anti virus or some other driver is slowing it down)
anyway just more testing needed and we will know enough... good luck |
Yes he has a SSD but he doesn't use that for encoding.
And a little correction my friend is using 2 WD Blacks in RAID0.
My CPU/RAM speeds are indeed forced in the BIOS. So all that energy saving crap is disabled.
When I'm running the baseline I also get around 250 fps.
My anti virus software isn't the problem because I had this problem already when I just had a clean install of Windows 7 with only the drivers installed for my motherboard and graphic card. And I used the same drivers as my friend did.
