Hi,
hi all, since this is my first Posting.
I sometime like to play a good round of Tremulous (OpenGL). If I start the game from KDE4 i have about half the framerate insted of starting it from KDE3.
Has anyone got a hint what I can do? Maybe it is a OS thing? Has anyone got experience running non KDE OpenGL Software/Games?
I use the current Kubuntu and have Nvidia HW.

thanks,
Hermann

Are you using compositing in Kwin? ( System Settings > Desktop )
Try with/without it to see if it makes a difference.

And also take a look at this: http://userbase.kde.org/GPU-Performance
Nvidia drivers had some major problems with 2d graphics. Recently they released 177.x driver which fixes this. Try upgrading and see if it helps you.

Thanks for you answers. I did try without Kwin acceleration and it did work better but still not the frame rate of KDE3. And something else happend during gameplay. It killed my Mouse inputs yesterday. The game poped into windowmode for one moment, and switched back to the game. But after that I couldn't use the mouse. Keyboardinputs worked though.

Well I will try it again.

Perhaps it was kded having issues again, that usually causes keyboard / mouse input issues.

Yes, i do get notified when someone posts a new post, but only if i goto that post first. i don't recieve any more notifications about that thread until i visit it.

I found that with XRender settings for Desktopeffects insted of OpenGL, the games work much better. I can live with that now.

thanks,
Hermann
