Both are supported, but it's not particularly heavy - it's only running at a monotonic clock of 25Hz (decoupled from display updates and deliberately chosen to not be evenly divisible with 60Hz to pinpoint animation issues).

Alas, the improvement that should really be made is to encode both n and n+1 in the same update and interpolate in the vertex shader, not hard here but I was lazy..
