Цитата:
Real-time priority is really dangerous. It's higher priority than nearly everything else. It's higher priority than mouse input, keyboard input, and the disk cache. If you foolishly set the priority class of a CPU-intensive program to real-time, it will suck up your entire processor, leaving no cycles for anything else.
In particular, since not even input runs at real-time priority, you can't stop it via any interactive means, because the thread that manages input can't even run to process your input.
Mind you, even if the input thread did run at real-time priority, that wouldn't really help you any. Sure, it could receive your input and distribute it to the appropriate application queues, but those applications are themselves not running with real-time priority, so all that happens is that your input gets quickly transferred to the input queues, where it then sits waiting for the applications to process them (which will never happen since the applications are not running with high enough priority).
устанавливая realtime приоритет, ты лишаешь драйвер видеокарты процессорного времени, чтобы обработать твои-же запросы быстрее.
