I'd think the calculation gains would be realizable by all modern computing devices. I figured they used floats because floats are standard and likely the loss of accuracy at 16 bits would be unwanted (not sure why though, gaming isn't say -scientific computing.) |
ofc pretty much all hardware can operate with half-floats, but the necessary components to do 2 at once is almost exclusively found in professional gpus
btw gaming engines are more and more like scientific computing, especially when using methods like ray/cone-tracing or physically based rendering
