Anyone who has tried to use Direct 3D from managed code knows 
why. They had the foundation to do everything from manage code, 
but chose not to.

You can get smooth animations in GC javascript on browsers too, 
but only if relying on the C++ CSS transition engine which does 
the frame-by-frame interpolation for you. But I expect javascript 
to get better at this if/when using true isolates. If the memory 
pool is small enough GC can work out ok, but for very low 
latency/overhead you use the stack/pools, not even malloc is good 
enough then.
