Download the latest winUAE version (at the time of this posting,
the current version is 1.6.1), and install it as an unsupported
game into it's own bottle using the winXP profile. The install
should complete cleanly. You need to change the default settings,
so start winUAE and you'll be presented with the control/launch
GUI (look at the screenshots section).
Go to the Host->Filters item, and set things to use Opengl (unsupported)
Go to the Host->Display item, and set winUAE to run in windowed mode.
With this setup, running in A500/wb_1.3 guise, I was getting a
constant 50 fps in 800x600 windowed mode across the amiga titles
I checked (Sounds of the Gnome, Stunt Car Racer, Frontier 1.05).
I also checked it with my clean workbench 3.1 hardfile image in
A1200/68030 guise, and it was getting the same 50 fps.
It's a bit hard to properly rank without a bit more testing, throw
some AGA games and demos at it and such - if it can keep churning
out 50 fps through some of the stuff I'll throw at it, that will be
good as gold :: right now, a bronze until I test some more. More
like a copper ;)
