This has the potential to radically increase performance" The hell does that mean, why run at "full floats" at all if half floats increase performance then. |
Half, single , double describe the accuracy of a decimal representation. The more bits you have the more information you can store in a variable and the more accurate your decimals are in calculations. But since gaming is such a high performance task the difference in performance between using a float(single) and a double can be significant. A half might not have enough information (at 16 bits vs. 32 bits) to perform the tasks that game developers need to perform accurately.
