Hope your not sick of me yet. Tongue

So I was just creating a sprite and I noticed it threw an exception about some AGPMemory. So I created some and it worked, but I have a few questions about this.

Is this basically an optimization only for nvidia cards and everyone else is using system memory? It says that in the docs but I just ponder on that. Is there not a generic way of allocating video memory?

The point: I'm not really confused so much as wondering what I can do for people with say, ATI cards, and then mabey everyone else.

It's a bit of a wanky design and it's all nvidia's fault.
No matter. Initialise AGP memory whether you've got Nvidia or not; if not, it just allocates system ram for you instead.

I guess I'll add it to the list of things I don't completely understand. Tongue

I'm trying my best to parse your code with my brain to see how I can use it. It seems to me if I wanted an ISO game or anything like that I would have to make some major changes to the sprite engine because of walls obscuring sprites. Luckily for me what I want to do is top-down and I should be able to just USE it. That's the hope anyways. Wink
