I heard that Quake was ported to the Dell Axim x50v/x51v. And that there's free download which includes Quake as well as a DLL for ogles. Is this true? Any ideas on its performance compared to Vincent?
If you use the native driver for the graphics chip on the Dell, it should be at least an order of magnitude (x10 - x20) faster. You might want to check out the PowerVR web site for the SDK.
