open gl hardware issues

[marcus]

Heres my setup

Combustion V3
Athlon 4400 dual core running windows XP 32bit at present.

When i disable software open gl in prefernces it has no effect on particle preview and rendering. ie: no realtime preview, slow rendering to ram etc.
I have tried nvidia 7800 pci card and quadro 3400 pci card.

I’m not a techie so i apologise if im being a bit simple about this but ive had to educate myself as ive gone.

Ive compared my system to a dual processor system with quadro 1300 graphics card. Particle preview is faultless, realtime playback on caching etc, works how id expect my system should.

Is it a 64bit issue or pci graphics card with older V3 comb software? Other applications seem to utilise the cards, ie: after effecs 6,5.

you need to switch view for the change to take effect. Also, particles run much faster if you have your view set to the particle operator rather than layer or composition.

This may be an iuuse with XP. There is a thread on the opengl groups that may be relevant. We have a dual core machine here that has Opengl issues as well….

A quick followup on the above.
We installed Windows 2000 on the machine and Opengl performance is fine – about a zillion times faster than with XP. Opengl does work with XP, it’s just very sluggish – we tried a couple of different cards, both high end, and several combinations of drivers with XP and could not get Opengl stuff to run smoothly. So now we are dual-booting the machine and waiting for Microsoft/NVidia to sort out their dual-core/opengl issues.
