balrogsoft: The problem is not the config of WinUAE, is Windows and its processes or tasks, if i open task manager i see 47 processes and only with 100mb of ram free of 512 mb that i have, only internet explorer opened, you are playing a 2d game (not only UAE, other 2d games running with DirectX), and sometimes it have little stops on the scroll, and with all programs closed, like antivirus and other programs. But as i said this is not the most important thing. I tired of PC's for other reasons...
It is possible to get smooth scrolling on a Windows platform, but most Windows programmers don't bother with VSync, unfortunately. It never ceases to amaze me that Windows gamers will boast about 100+ frames per second, oblivious to the fact that if the framerate isn't in sync with the display, the game will look WORSE. It doesn't pay to go too fast, but, try explaining this to someone who never grew up with the Amiga. :roll:
Linux and my Mac aren't any better.
The number of processes doesn't really matter, so long as they don't all want the CPU at the same time. Antivirus software, in particular, is really nasty at slowing down a Windows computer, which is why I don't have any.
With VSync turned on, you shouldn't have any trouble getting smooth scrolling in WinUAE. I've noticed, though, that dual core processors, or chips with hyperthreading will cause [sometimes quite severe] framerate issues with WinUAE. WinUAE is pretty good as far as compatibility is concerned, but I can't say it's very stable or refined. But, hey, it's free. :rtfm:
