OpenGL...optimizations?

This is a discussion on OpenGL...optimizations? within the Game Programming forums, part of the General Programming Boards category; I was wondering what some optimizations there are for OpenGL? I know about Octrees and far clipping, but are there ...

    OpenGL...optimizations?

    I was wondering what some optimizations there are for OpenGL?
    I know about Octrees and far clipping, but are there any others?
    Also what is a good far clipping distance?

    any help will be very much appreciated,

    display lists, vertex arrays, google, etc...

    These are algorithms for graphics in general, they're not specific to OpenGL. In addition to those frustum culling comes to mind, backface culling, LOD rendering, the list goes on forever depending on what your doing specifically.

    >> Also what is a good far clipping distance?
    This really depends on the scale at which your rendering. Theres no single value thats better than another.

    I read the thread title and though you meant video card specific extentions which opengl does support
