I started developing my GP2X game in 640x480 and found that it was quite slow, jerky and unresponsive on the GP2X itself compared to running in GE. I tried it in 320x240 and the performance was much better on the GP2X. Also the graphics appeared to have been scaled down in 640x480 to make them fit, as the quality of the sprites was actually better in 320x240. So which resolution do GP2X game developers prefer? And is there a way to improve performance/graphics quality in 640x480?

The 640x480 resolution is for use with the tv-out adaptor. The screen on the GP2X only displays 320x240. So I would develop just for the smaller size.

OIC, thanks for the info.

I'm developing in 320x240.
