Interesting thread, I have often wondered about this but never asked.(posted 9900 days ago)I actually just got a new machine for home, which will now become my primary place for recording scores (as opposed to my work machine before). The new system is a P2-450, 128MB RAM, and a Viper v550 video card. So far, it has run everything I've tried at 100% with no frameskip (hehe). (FYI, the work machine I was using before was a P2-300)
Regarding the minimum percentage of original speed for me to playback, I'd have to say between 90-100% (only ranging down to 90% because I noticed a few games that seemed to be 100% were actually running 5-10% slower). If I notice the game running slow, I will adjust the frameskip to get it to 100%.
