Slowdowns at higher resolutions in Windows ce

[Einlander]

I have an htc touch pro2 running a custom rom with the latest opengl drivers. It has a screen resolution of 800x480. If i write a simple 3d program such as the one for the x_cullmode example, it will run at about 5fps, but if i were to go get an opengl game it would run at 50+ fps or even an opengles demo progam which would reach 0+ fps.

I like the ease that glbasic provides but i find it unbearably slow at higher resolutions. its decent at 320x240 on my htc kaiser/tilt but it has opengl glitches where it simply dosent render correctly, same on the touch pro 2.

so bugs:
Massive speed slow down at resolutions > 320x240
Rendering glitches in simple objects

the last one i will provide video if needed

I'm not using OpenGL|ES on WinCE, so far. I have to check how to do that, still.

ahh, that might be the reason. Is it using direct3d? if you need help i have 4 devices i can help you test on 1 wvga(touch pro), 2qvga (kaiser and wizard), and 1 sqvga (blackjack2)
