I mentioned this in another post but I though it would be useful to make a new post.
For those of you who don’t know about it, there is a wonderful utility called Display Doctor made my SciTech. It can optimise your graphics card, increase compatibility for old cards, etc. It even comes with a utility to allow you to use OpenGL for non-supported cards! Anyway if anyone is interested and thinks it might help them, you can download a trial from www.scitechsoft.com.
