IMO plot x,y is fine for experimenting things, but better way is like vinylpusher wrote, use WritePixel or WritePixel fast.
Gabriel, "anything with nvidia" comment, it is not so, you just have to take a moment to check out what commands are slow in current GFX card scene... some are slow with Nvidia, some with ATI, some with uh,.. are there any other real GFX cards around :D It is also other way around, you can't expect intel GFX card to push 20 million tris/ frame like some nvidia or ati can.
