Should you set priority to realtime?
No application should use it except in very specialized circumstances, and even then try to limit its use to temporary needs. Once Windows learns a program uses higher than normal priority it seems like it limits the priority on the process. Setting the priority from IDLE to REALTIME does NOT change the CPU usage.
What happens if you set priority to real time?
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.
What is the purpose of having a real time process priority in MS Windows?
Even though the RT priority wouldn’t mean quicker/faster processing for a given process, as it enables you to know that something is definitely happening also if the computer is busy and it is useful for data acquisition processes.
Does real time priority increase FPS?
Giving a process a higher priority won’t make it go faster. If you put any process to high priority it will increase performance because it allocates more resources to that specific process – that’s the theory but not always ‘true’.
Is setting high priority bad?
In this case high or real-time priority should be fine. Unless you’re on a single core, go ahead, experiment. Most of the time it won’t hurt to set it to high or even real-time. You can set the affinity of a process (how many cores it can use) in task manager as well.

Is real time priority good for gaming?
Unless you are running another program at the same time as the game (e.g. downloading a file in the background), setting the priority in this way will have absolutely no effect on the gaming performance. Priorities are just relative to other running tasks.
Is setting high priority in Task Manager bad?
Giving a process a higher priority won’t make it go faster. Your programs will never use more CPU time than they need (or more than 100% obviously). It just means that if you have two processes that both want CPU time, the one with a higher priority will get it.
Is it safe to set high priority in task manager?
Be warned that if you run applications at high priority, that may slow performance as other application get less I/O time. (See also, “How can I improve I/O performance?”). To use the /realtime option you have to be logged on as a user with Administrator privileges.
How does the’real time’process priority setting work?
It also won’t boost the priority of threads in the real-time priority class. So a High priority thread won’t get any automatic temporary boost into the Real Time priority class. Russinovich’s “Inside Windows” chapter on how Windows handles priorities is a great resource for learning how this works:
How to make CMD work with realtime priority?

Which is the highest priority setting in Windows?
It’s actually high enough that it could cause starvation of the keyboard and mouse threads to the extent that they become unresponsive. Real-time is the highest priority class available to a process.
Can You boost the priority of a thread in Windows?
Windows will sometimes boost the priority of a thread for various reasons, but it won’t boost the priority of a thread into another priority class.
