I have noticed that most every program created here loads up your games very slow other then AppGameKit .

There also memory hogs

I played with all of them

fpsc
dark basic pro
Game Guru

and played a lot of demos and games.

The only games that do not take a lot of memory and loads very fast are game created with AppGameKit .

Why is this?

Because AppGameKit rocks!

lol, dont know about DBPro I never used it but FPSC and GameGuru are doing a whole bunch of loading things, agk is loading only what you told it to load, believe me in a heavy 3D project with a whole bunch of textures and AppGameKit is goner lag out a bit to, download a few high poly models with 4k textures and load them you will see a massive difference, not only that DirectX .... OpenGL is faster

So its a combination of the way it was built and the render pipeline.

OpenGL is faster

I know that is true, I am not talking about 3d models because I downloaded a lot of game examples with 3d models nd they all load real fast.

fpsc, real slow

dark basic pro, very slow to.

Isn't AppGameKit DirectX also for 3d?

No, it uses DirectX for sound on Win8 for some odd reason but 3D is OpenGL, DirectX is windows only.

DirectX is windows only.

but I loaded dirrect x models in my phone. I wonder how it handles that.

.x is just a data file, assimp just reads the data and formats it into something OpenGL can use to render it .... its just numbers! lol

its just numbers! lol

That's true, never thought of it like that.

I guess it is easy to convert each model into whatever the phones use.

Yup, that's what assimp does (Open Asset Import Library) (AGK uses this internally)
