I’ve tried demos on Intel 82845G/GL (?) video card and it 's prompted

Exception in thread “main” net.java.games.jogl.GLException: Unable to enumerate pixel formats of window using wglGetPixe

Any idea ?

I had the same problem with that controller on a Dell. But then I have been having lots of problems with jogl since I moved to the latest versions :frowning:

However in this case a driver update fixed the problem :slight_smile: On that machine I’m now at driver version 6.14.10.3865.

FYI the next problem I had on that machine was the prossesor being hammered, but maybe that’s just my bad code!

Hope that helps

Tnks a lot ;D

Could you tell me where you have kept it ?

Use the wrong one is sometimes really dangerous, expecially on windows :-/
