Also, the wiki is dead. It became a spam fest so I had to shut it down.

And by the way, nice post!

Nice, so now I only need to discover what "Use VBO", "Hardware Transform" and "Ignore illegal reads/writes" does and this post is complete.

Use VBO is another way to send dynamic vertex data to the GPU. It doesn't seem to give much of a speedup, it's just an experiment.

Hardware Transform uses vertex shaders to do T&L on the GPU instead of doing it in software on the CPU. Can be faster or much faster depending on game and hardware. It should be identically visually to SW transform but it isn't, there are some small differences between the implementations.

Ignore illegal reads/writes is a debugging feature, can ignore it.

Thanks Henrik, now it's completed.

Later I will describe the rest of the options if it's interesting for someone.
