In this video Joachim mentioned that there is a new math library involved with the new compiler tech but I only saw mentions about floats, half floats, float/4. This really puzzles me, is Unity still going neglect doubles? I really hope new math library will take Unity up to date and finally fully support doubles too, at least for non-mobile platforms. Additionally, I'd love to have (optional) scene transforms in doubles too but I doubt that will happen anytime soon as PhysX can only handle single precision floats. There are other physics engines out there that do handle doubles (Bullet for one) and it would be great to be able to keep the scene in higher precision without obvious issues when going furher away from origin. This would be especially cool now that HD Render Pipeline will have camera relative rendering as these things combined would be perfect match for huge open world games.
