The problem is that you're playing the game all stretched out. Play it in it's intended size, and I'm sure it'll run smoothly.
indeed.
either resize the window or use HTML and make a page with the resizing, save that to yo computer, and play it from that .HTML file
for clarifications
here is an example of resized .SWF files, using
oh year as an example off of my website
http://tabsfilesandstuff.webs.com/i'm_ALIVE.htmlthe code used here is
<object width="512" height="384">
<param name="movie" value="http://tabsfilesandstuff.webs.com/ab92d03bbcb8a2094f40450b7f9ab81c.swf">
<embed src="http://tabsfilesandstuff.webs.com/ab92d03bbcb8a2094f40450b7f9ab81c.swf" width="512" height="384" allowScriptAccess="never"></embed>
</object> <br>
alternatively, unresized, which is what you're using, you can see here the mild slowdown (though this is a really easy flash, so it really shouldn't even be present at all :T)
http://tabsfilesandstuff.webs.com/ab92d03bbcb8a2094f40450b7f9ab81c.swfthis is the raw file, so there is no html at work here.
tl;dr
make an html file simply with
<object width="yyyy" height="yyyy">
<param name="movie" value="xxxx">
<embed src="xxxx" width="yyyy" height="yyyy" allowScriptAccess="never"></embed>
</object> <br>
with xxxx being the file path to the raw file you have saved, or even the online file (though you obviously need internet access for that), and yyyy being the dimensions (either guess, go with what you find comfortable, or check the source code of the page you got it from)
i guess you don't really need
allowScriptAccess="never"
either but whatever
