Ran benches with MameUI64 .141 in Win7 x64 4.5Ghz i5 2500K (2 x 2GB) 240-Pin DDR3 GeForce GTX550-TI Bus clock 100,CPU multiplier 45
MAME 0.141 64-bit mamedev.org official binary, -bench 90 used for all games to match John IV’s latest Wolfdale run. All games had no nvram except scud and gradius4, which don’t show gameplay until configured. All numbers are % speed where 100 is full framerate.
I copy and pasted whats above off of RB's site I only used John's mameui64 1.41 not sure what bench 90 means. Also did not mess with nvram settings would not know how anyway.
Some of the numbers seem off to me especially gauntleg,starsldr. The numbers fluctuant alot in game so I'm giving you a avarage. I'm not sure how or when RB or John gauge theirs.
