Sure let me just take another 30 min to render

30 min to render?

??

This might be how long it takes to display the image. 3D can be very complex sometimes.

Ooh that has always bugged me about 3D, to get things to look nice it takes ages to render (my PC is not very good but it should be more then capable to do some 3D work) and then it turns out there is a glitch in your renderings...let's do it again shall we ....annoying....

I hope someday rendering over the GPU and CPU at the same time will be made possible, the GPU is extremely powerful and outwhit's the CPU without a doubt plus it's often cheaper and easier to replace...

I have seen hospital's who just make a supercomputer out of 4 high-end GPU's, saves them like $20.000 on a computer-farm...

So... 3D images take a lot to render, I wonder about 3D games, they must take ages to compile, even with those super CPUs

Rendering in games is not done by the same ways like 3D Studios does it. The game engines render in real time, fast enough to use 3D in 30FPS Games.
Btw, I wish I could use the game renderer to render my Blender animations. o.O I wonder what the different between this render methods is. The quality difference is not much, but games render extremly faster.

the difference is that one is hq raytracing and one is not. game engines do not produce the same quality models as blender etc..., but they typically have AMAZING textures which hides the fact quite nicely

Yeah that's what I thought. There are much less polygons to display I think. I saw a demo of a game with actual textures, not flat images giving the impression of textures, on Youtube, and it seemed to render slowly even on an incredibly fast CPU. Now imagine with shading/lights.

What is the loading at the beginning of levels for? Is it mostly to uncompress textures and map data then load them into RAM?

Yeah true. The worst loadings are when it doesn't say how much time is remaining and it takes 30 seconds, or even worse, a black screen with no loading messages. When possible, it's good to display an animation or do other stuff, but make sure it doesn't slow down loading speed considerably.

Well yes. Of course this differs per game but in general models are loaded, texture are loaded and 'wrapped' over the models. Swap models are loaded...basically it is just loading the pieces that make up the world not the game code that makes it turn up on your screen in the first place.
I hope one day we will get UnlimitedDetail instead of poly (search YT for Unlimited detail to see what I am talking about it's kinda hard to explain). There are three ugly things about poly's: raw edges, swap models (in a game there might be three models of a tree, a far-away, low detail model, a mediocre detailed model and a close up highly detailed model) and last but not least, hidden geometries. Poly's are also quite hard to do collision detection with because you are suggesting roundness by stacking a bunch of poly's together in a circular shape, however each of these poly's has a different bounding box so it works pretty inacurate in physics...

The good thing is that it is pretty lightweight on memory which is why we are often still counting in MB's when talking about the RAM on a GPU and not about GB's (well okay, there are some 1-2GB gpu's out there but they are pretty high-end)...
