Is there any other way to use opengl es without using SDL 1.3? If it is possible to use SDL 1.2 for input (and sound, etc), and somehow draw with opengl es then it is fine for me.
I checked the Propis demo, it works on my device but there is awful rendering artifacts on the screen. It seems...
Did anybody try the new OpenGL ES of the firmware 1.2.0? Do I understand well, that with a better opengl binary, I could use the original 1.2 SDL with 3d hardware acceleration? I need the touch screen support and SDL 1.3 do not have it.
I render around 1200 triangles (4 tile layers - 2d stuff) in my game, 3 of the 4 texture atlases have perpixel alphamap. It is 20 batches with sprites and effects. Currently (without any optimization) it runs at 25 fps if i use floats, and 28-29 fps if i use fixed math.
Sorry, a little fix: '..when rendering 2d geometry...'. What is the performance difference when rendering 3d geometry? It could be the same if the 3d hardware has hardware TnL i think. Or if the cpu has the same tnl performance with fixeds and floats. :)
(1) This is the code of drawing only one tetris block?
In this case you should batch your draw calls, e.g. collecting all the static blocks into one buffer and render it once.
(2) Or do you render the whole game screen into a texture and draw it onto 2 triangles?
Texture creation is a slow...
I have very limited experiences yet, but it seems that the 3d hw of wiz is not slower than the PowerVR MBX Lite of the iPhone (not the 3gs with the SGX and Cortex-A8). It should be far enough performace for a tetris.
My game is a little bit faster on the wiz, but it can be a simple lucky...
Maybe i misunderstand the situation and the problem, but now developers write a little a script for their apps, that runs the application and restarts the menu when the app quits. Maybe the scripts could be a little more intelligent and it could start the right launcher after the app quits, e.g...
I also mentioned this feature on my idea-list here: http://www.gp32x.de/board/index.php?/topic/50498-wiz-software-ideas/. Maybe i will create a little test program that does nothing, but turns off the screen and sleeps, and i will check the baettery life while running it. Of course this...

If i understand well, the menu exits when you start a program, and reloads on quiting. Maybe i'm wrong.
