I’m going to stick my neck out and say this isn’t going to help. 
PREEMPT_RT is for hard realtime, like pro audio/music processing where you 
have to send/receive so many bytes every millisecond, otherwise quality 
noticeably suffers. Things that are limited by human reflexes, like video 
games, likely will not benefit. Human reflexes are measured in tenths of a 
second, which is plenty of time to get things done in non-realtime 
kernels.
