In the latest build of the game (0.15.16), we’re now creating the game map on the GPU, instead of on the CPU. This is much faster (at least for me and on every computer I’ve tried), and some parts of the process (particularly patching the terrain after it’s been built) actually build nicer-looking geometry as well.
On my main development machine, it’s gone from taking about two seconds to build the full terrain down to being almost instantaneous. On my older laptop, it’s gone from taking about four seconds to taking just a fraction of a second (albeit with a short stutter). I’m hoping that other folks see big improvements, too, and that it works for everyone!
If you’ve had a chance to play with this build, I’d be very grateful if you’d post a reply, letting me know whether the GPU-based map building worked correctly for you, and if it was noticeably faster than before. I’m especially interested in anybody who has an AMD video card or an integrated Intel chipset, as I’ve been unable to test it in those situations, yet; all my computers happen to use NVidia right now, which is a little unfortunate for testing purposes!
