Sorry if this is covered clearly somewhere in the FAQ, Wiki, or introductory guides, but I haven't been able to find much information.
Most of my experience with Linux has been on a system with no hardware accelerated OpenGL capability (Sony's now-deprecated OtherOS / PS3 Linux). Having seen videos of the RPi running Quake 3 I was hoping to finally be able to run some OpenGL / 3D applications and games without much trouble.
Having played around on Raspbian for a while It's now becoming obvious that it's not that simple. Games like "Brutal Chess" are not going to work "out of the box" at this point. Emulators such as Stella (Atari 2600) and VICE (Commodore PET/VIC20/C64/128) with OpenGL support won't allow you to enable OpenGL (at least not without modification?).
So I've read a little about OpenGL vs OpenGL ES and the RPi's implementation of X, but am hoping someone will come along and explain the current status, where things are headed, and so on ... also, if it isn't already, I believe this information should be clearly posted in the new user section and/or the wiki to help set expectations.
Will "normal" OpenGL support be coming at some point so we can run things like Stellarium, Brutal Chess, BilliardGL and whatnot from X or would all these types of applications need source code modifications to possibly work?
