Project in OpenGl with very low fps

Asked by Pedro Cunha

Model of graphics card: Nvidia GeForce 425M
Computer: Asus N53JQ
Version of Ubuntu: 11.04

Logged in with Unity Classic

Well, I have an OpenGl project that simply draws a table, a floor and three axes, with rotation implemented by mouse click&drag. Problem is, it is not dragging. Or rather, it is, but with a VERY low fps. Have tried in Ubuntu Classic (no effects) and it runs smoothly. Not sure what the problem is...

Thank you.

Can you give the output of:

sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia

Thanks

I went out on a limb here and decided to go check the version of the Nvidia drivers, since the output of the command you gave me gave me an older version. I noticed that the vsync check box was not ticked, even though it was on CCSM. It solved my problem...

For your benefit, though, here's the output. Could you have found the answer through it?

I mean the VBlank option in OpenGL settings, down at the NVIDIA X Server Settings menu. For some reason it required it to be on as well as the option on CompizConfigure Settings Manager.
