only 60fps with nvidia 3D vision

[rav]

Hi,
we want to upgrade from xp and crts to win 7 and tfts.
Right now I'm testing everything with a Samsung Syncmaster 2233 connected to a quadro 4600.

Shuttering works just fine with viz.QUAD_BUFFER, but the framerate gets locked to 60 fps. If I disable 3D in NVIDIA's settings, it jumps back up to 120. In windowed mode, it's also 120 fps.
Unfortunately this reduces the time resolution of viz.UPDATE_EVENT and waitframe(). Is there a way to force vizard to work with 120fps?

Hi,

Can you try the following code and see if you get 120fps?

import viz
viz.setOption( 'viz.max_frame_rate', '120' )
viz.vsync(viz.OFF)
viz.go()

Best,
Masaki

Hi,
sorry for my late response...

Disabling vsync does not improve the framerate, but you get these typical glitches, where the frame is not completely rendered. The program still runs at 60fps in fullscreen mode.

Hi rav,

This morning we got a nvidia 3D vision glasses kit and compatible 120hz moniter, but we cant seem to get it to work with Vizard. When we try our code it goes into quad buffer mode but does not sync up with the glasses.

Do you have nvidia 3D vision pro? if not what setup do you have?

Any help would be appreciated.

Thanks

Hi,

we're using the standard 3D vision kit, not pro. But I don't think there will be much difference.
Enabling 3D in NVIDIA's display settings and selecting the USB emitter as displaymode was enough to get it to work with worldviz. But it only works in fullscreen mode.

Thanks Rav,

We had the settings already set to what you suggested, we just didnt have the monitor set to 120hz.

It works now, and it looks fantastic.
