Oculus Rift and friends. VR needs extremely consistent latency and has very tight deadlines. Ideally, you render 90 FPS and never miss a frame. GC pauses are out of the question, so if you're going to use GC, you need to be real-time without any degenerate stop-the-world cases. The linked article ostensibly delivers this, but there's no real-world evidence. Given your tight time budget, you also don't want to pay the "GC tax". GC just makes your life harder in this environment. There also isn't really any good reason to write a 3D engine in GC'd languages given a) existing C++ engines and b) sightings of Rust on the horizon.
