Buffer update performance #118

Closed kateyy closed 10 years ago

kateyy commented 10 years ago

This increases the performance for our frequent buffer updates:

particle drawable vertex buffer
terrain height/element id buffer

We cannot use glBufferStorage :( (requires Opengl 4.4, not supported on my mobile gpu). But nevertheless this keeps the frame rate constant while modifying the terrain.

Compiles and runs. But I don't really recognize the changes.

Doesn't really change anything for my desktop, but as mentioned, it keeps a constant frame rate while modifying the terrain, on my not so fast mobile gpu.

Getting some more fps (with the last commit), +faster interaction. So please review =)
