Updated x264 binaries to r1109 (Skystrife builds).
My recent test shows significant speed-up between 32-Bit and 64-Bit:
Code:
Source: C:\TEMP\x264\sample.avs
Params: --crf 22 --subme 9 --me umh --analyse all --8x8dct --bframe 4 --b-adapt 2 --ref 6 --b-pyramid --trellis 2 --weightb --mixed-refs --direct auto
[Type: 32-Bit, Pipe Buffer Size: 0 MByte]
encoded 2262 frames, 55.68 fps, 457.49 kb/s
encoded 2262 frames, 57.09 fps, 457.49 kb/s
encoded 2262 frames, 57.88 fps, 457.49 kb/s
[Type: 64-Bit, Pipe Buffer Size: 4 MByte]
encoded 2262 frames, 67.55 fps, 457.49 kb/s
encoded 2262 frames, 67.08 fps, 457.49 kb/s
encoded 2262 frames, 67.18 fps, 457.49 kb/s
That's a nice 20% speed-up for high (but not overkill) settings, even though the pipe is involved
