When I use auto frame rate I still get constant 60fps with ZSNES. It skips frames based on performance, and as I have a fast enough processor, no skips are needed.
The SNES does skip frames, but a PC does not need to if its fast enough. Skipping frames makes the graphics and sound worse quality. I always aim for the best possible quality, and avoid things like scanlines, frameskip (if I can) and low resolutions.
Anyway, I only see advantages in slowing games down (Helped me in Yoshi's Island to get pixel perfect jumps)
Slowing games down = cheating.
Skipping frames doesn't make the graphics and sound worse. SNES uses built in interpolation which includes some form of keyframe work... compare animation fluidity at PC 60fps / Auto Frame Skip with and without Interpolation. (I recommend standard 2xSaI for normal play, with a few notable exceptions like StarFox)
And the sound isn't worse because
it's exactly the same. In fact, it's better if you do allow auto frame skip because it plays back
exactly how the developer intended... same as the graphics.
Added: OK, I take it back. Auto Frame Rate is what you should use, period, but for a different reason.
Just talked to pagefault about it.
0 frame skip runs *everything* as fast as your system can run it. If it's slow, that means your system is too weak. Auto frame skip will be slower if your system is too fast, and faster if your system is too slow. Neat stuff.
Auto Frame Skip attempts to simulate how 0 frame skip would run on actual SNES hardware
