Sorry for the late reply, always deadlines to meet...

I found (un)DelphiX extremely easy to use, but since starting this topic, I've downloaded and tried GLScene, and must say I'm pretty impressed with what they're doing. As for building the renderer from scratch, I lack the skill (newbie) at the moment. So for now I'd rather go for a library that's well maintained by a community, which I can use to learn the tricks of the trade.

The DelphiX version is the latest version downloaded from http://www.micrel.cz/Dx/. I wasn't impressed with the frame rate I was able to achieve from using DelphiX. A mere 60 fps for a animated cursor and console... Maybe I'm doing something wrong? I'm in the process of adapting my newly developed kernel to use with GLScene to see if there's any difference in performance.

I'll download JEDI-SDL tomorrow and play around with it... Thanks for the suggestions
