At present there are not too many games that run, but the speed is there. As Fish was saying, it is possible to modify the sources so that will more games such as Half-Life can be played, also I guess OpenGL can be made to work, though I've had trouble getting games to run smoothly in GlMode under DosBOX on Windows, but maybe there's something I'm missing.
Sadly, Fish is having computer troubles, so it may be a while till we see any advances, but in the mean time I figured I'd upload this little photo just to show that Windows can indeed be ran inside of AROS! 
Photo taken on a machine running at 2.6Ghz.
An easy question, I saw your screenshoot, DosBox runs software but this is under img, how I can make this images, because it is How the other virtual machines on Windows? aslo I'll like run DR-DOS the best PC Dos system.
