Running HW-accelerated games (using OpenGL ES2.0) is possible even today by stopping the hildon-desktop (compositor) first. I have a version of hildon-desktop + libmatchbox2 + libclutter that allows switching off the compositor when your window is shown with a special window property. This works, but when showing, e.g. the power key menu (or system-modal dialog on top of your game), it takes about two seconds to switch back to the compositing mode. I don't see how this two-second delay could be reduced, and it could be that the delay will stay about the same due to required reconfiguration in the X server and 3D drivers. However, this is already faster (and more convenient) than stopping and restarting hildon-desktop, and it is also possible to task away from your game to another application and switch back to it later. > To me, this is a very important feature for any future device, and I > was disappointed that this is not apparently a high priority within > Maemo. Probably because the device is not designed as a gaming device, Nokia has other devices that focus on gaming. > I really want the next Maemo device to succeed, and one of the first > things the gadget blogs and technophiles will want to see is the > games.

I think the community developers can port 3D games for it, and they may even run fast enough, but it's no PSP. > I also admit I might have been influenced by the video of Quake3 on > the Pandora. :-) > > I also don't expect Maemo to port the games, I'm just concerned that > the path will be too thorny to encourage others to do it.
