[osg-users] osgMemoryTest

I'm on Vista 32bit. 

Smaller textures seem ok:

512x512 - 972 before 'out of memory'
512x256 - 1000+
256x256 - 1000+
etc.

1024x512 - Error
768x512 - 229 before 'out of memory' (seems very low)

Given my recent problems with osgText i'm guessing this a driver issue. Unfortunatly uninstalling, cleaning and reinstalling the NV drivers isn't solving it.

I feel a clean vista install is fast approaching.. sigh.

Hi Kim,

I've just tested the below osgmemorytest line and it runs OK, but was
slower my system down at around 800 textures created, so I stopped it
going further.  I have a Gefore 8800GTS 640Mb  card + Kubuntu 8.10.

What OS are you using?

What happens when you try smaller texture dimensions?

Robert.
