Frame Rate & Autoframeskip ?'s and other ?'s

DethLord · Post by **DethLord** » Tue Aug 03, 2004 4:54 am

Is there any difference when you leave the autoframeskip option on or off? If I do leave it off will that make the game run smoother. Sometimes on some games when I get 45 FPS or even 55 FPS i can see some, but rather minor jerkiness in the game.

I am using ZSNES 0313 WIP Windows Version. My specs are Celeron 366, WinXP, 192 MB RAM, 4MB Video. Since I am on the laptop, whenever I use the 640x480 resolution, i can see the big black border surrounding the screen. I use the DR mode for 640x480 b/c the other modes, I get at most 10 FPS while the DR mode I get anywhere from 40 - 60 FPS. I like the 320x240 resolution or was it 320x200, anyways that resolution it pretty much fills up the whole screen, but that was another emulator and I don't think ZSNES win supports that low of a resolution.

One last question, what would be the optimal configuration for a slow computer like mine to get 60 FPS pretty much anywhere. Thanks for your help and sorry if I ask a lot of ?'s.

The game should run smooother if you have auto frameskip off and set at zero, but this requires more CPU power.

Try out ipher's optimized ZSNES builds to see if ZSNES runs faster for you. Some users reported speed increases with these builds.

When I take off auto frame skip, then it's too fast. So I turn on vsync in video options, and it doesn't help.

enable auto frame rate and put 9 as the max frame skip.

That will make it really choppy, right?

Wrong. Well, at least not if your compuer can handle it.
Auto frameskip means it will skip up to N frames if your computer isn't fast enough.

Try running ZSNESW.EXE with the -6 command line option then set VSYNC on.

zsnes (I left my brains in the womb).exe -6 forces 60Hz refresh.
