With respect to gaming, the answer is a definite "maybe". Here is the thing with a real time kernel, context switching is expensive, and especially so when going between kernel and userland mode. This is because you have to save/restore all the registers on the stack so there are a lot of memory cycles involved in a context switch. A realtime kernel increases context switching a LOT so you're going to eat more CPU than you otherwise would but on the other hand, critical things will get attended to in a more timely manner. So whether the latency or the overall computational efficiency is more important will make the difference in gaming. Also to some degree hardware, most games will only use 4 cores or so, a few more than that but most only about 4, so if you've got an 18 core machine, you have plenty of core for the extra kernel overhead, it is more likely to benefit than if you're on a 4-core machine with all the cores already saturated.
