Hmmm, what kind of video card do you have? Or is this a laptop? If the latter, then you can't upgrade OpenGL because the GPU integrated into the laptop won't support it. If desktop, then you'd need to check the video card specs. If it tops out at OpenGL2.x, then that's all it will run. Every time they do a whole number upgrade of OpenGL they change something critical based on the hardware used in development. Supposedly it scales, but if the hardware lacks the buffers needed, then it won't function.

Not tying your computer up all night rendering is a different issue. If you intend to only run one computer, then buying the hardware with system ram and processor speed to cut render times will be costly. That was why I was asking about the possibility of building your own. You save a lot of money you can put towards a beefier video card and system ram.

An alternative would be running a distributed renderer. Let it be known that you'd be willing to take old kit off of people's hands. You can build a small rendergarden that way for almost no investment (only things you'd have to buy is a network switch for all the comps, and a KVM switch so you could run them all with only on keyboard, monitor, and mouse). Poser's Queue Manager will run both distributed animation rendering and distributed bucket rendering. I know it worked with the old renderer and Firefly. Don't know if it works with Superfly, so that would need to be asked.
