View Full Version : low frame rate

02-13-2009, 12:02 PM
I am working with artoolkit, the frame rate is terribly low.

It seems opengl is not running on my hardware, I tried to

update my driver but did not help.

I am using a laptop with Nvidia Geforce 8600M GT, I think

this could be the problem(different from the desktop version).

Any suggestions how to improve the frame rate on this machine?

What do you mean by "low" ? 10fps ? seconds per image ?
Isn't the artoolkit computationally expensive ?
driver version ? OS ? check you are not on the battery, and check the energy saving modes.

yes very low, I only display a cube, it's only 9fps.

it should not be that expensive.

I am using windows xp, driver version

I am not on battery, have my power cable connected.

Have you tried compiling/running any other OpenGL example? Or try GLview [http://www.realtech-vr.com/glview/]. Check the available/capable extensions.

Possible cause: GFX drivers doesn't install correctly.
Solution: Uninstall GFX driver. Do cleanup [ccleaner - http://www.ccleaner.com] restart and reinstall the driver..

I have tried Glview. What am I suppose to look from available/

capable extensions? I tested it with all the versions. And there

is no problem, all passed.

There are 2 drivers?

GDI Generic the one come with windows?

and my hardware Gefore 8600 GT.

I try to test the GDI Generic which gives a very bad result.

Am I rendering opengl on this one? how do I shift it to my

I think either PFD_DRAW_TO_BITMAP or PFD_SUPPORT_GDI will force a software context.

Haven't looked at Artoolkit yet, but I would think it would have all this stuff wrapped up for you.

Try giving the manual another good going over.

You can ask Artoolkit specific question over here


Hope it helps.

"I have tried Glview. What am I suppose to look from available"
do render tests with all options on. see how it performs and what version fails.
