im trying to get deep into houdini, but everytime i try to render looks like my machine works very hard for simple renderings, is any special open gl driver needed or something? i dont think is the hardware because ive rendered before with maya mental ray.

so i dont know if houdini is being unestable on my workstation because the need or some kind of open gl driver or framework to make houdini work fine and smooth.

as far as I know rendering is based on cpu… I don't know that graphics drivers will make a difference.

Is it the whole render that takes long or the opening of the render window? I find that compared to some other apps it takes quite a while for mplay to open. “Evaluating Python…” The render view tab is very good though. Try that.
