Frame skipping? Is there an opposite?

Hi,

I know there is frame skipping, and I know you can disable automatic frame handling.

These are cool features, but I would really love to see the opposite of frame skipping, where extra frames are rendered. I have an extremely fast computer.

I have used the automatic frame handling, but the screen does not move smoothly. So I disable the auto frame handling and set the frame skip to 0 and it's as smooth as silk...but it's just too fast.

If there was an option to render extra frames it would be just awesome. Then I could just select +1 (for 1 frame extra for every frame rendered) or +2 (for 2 frames extra for every frame rendered).

This would slow it down a bit and yet still maintain that silky smooth scrolling.

So, is it possible to render extra frames? Say 1 extra frame, or 2 extra frames, etc?

Even rendering +1 frame would be great as it would provide half the speed it is now yet still maintain the silk smoothness.

Any help would be appreciated

John

Try Vsync?

Tried Vsync

Also tried running it with the -6 and it's still the same. Tried with the -K switch and it won't run at all.

I'm at a loss as to what is causing this, but I'd really like the ability to render 1 frame for every 1 displayed, so in effect doubling the number of frames rendered but keeping that smooth scrolling.

Thanks for the tip.

Use a filter or two.

Filters don't have anything to do with it.

If you're using -6, and enable triple buffering, it should all work perfectly when using auto framerate. If not, then there's probably some external problem.

I read your post three times, and I still can't believe I'm reading it right.

Are you seriously requesting that ZSNES render frames that aren't there?

You can also set the maximum frame skip to zero, so automatic frameskip becomes frame rate throttling. Otherwise, you will need vsync and a 60Hz video mode for proper speed regulation.

Yeah it sounds to me like your using vsync, but the video mode is probably using 75 or 85 Hz. If your monitor has an OSD, while your in game, go into the OSD, and often there is an item that tells you current resolution/refresh rate. If the vertical refresh is higher than 60 Hz, that is your problem. If you happen to have a DirectX control panel, you can force 60 Hz on whatever video mode you want to use. But if you don't, you would probably have to set it manually somewhere in the registry. I couldn't tell you where off the top of my head though

Anybody know why I can't get Earthbound to scroll smoothly? Every other game I have tried is smooth except Earthbound. I don't understand, it's very choppy just walking around.

I run Zsnes at 640x480DR Full @ 60Hz with Triple Buffering enabled. Specs are in my sig, and like I said every other game I've tried runs smooth.

Some games just use weird scrolling. Don't know why, they just seem to be scrolling with varying distances per frame, or something. Madou Monogatari is another such game.

There is a difference between vsync and the triple buffering option. This person has stated they tried vsync, but I haven't seen reference to them trying triple buffering.

If that doesn't fix it, then yeah, I'd agree it's a refresh related problem. Try running ZSNES in a windowed mode on your desktop and see if the scrolling problem is still there.

This is the solution to your problem, just verify you're running ZSNES @ 60 Hz and turn on VSYNC.
