It would be the highest available priority setting, and would usually only be used on box that was dedicated to running that specific program. 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. Therefore, it is different from 'High' in that it's one step greater, and 'Above Normal' in that it's two steps greater. The process priority class raises or lowers all effective thread priorities in the process and is therefore considered the 'base priority'. Since real-time is supposed to be reserved for applications that absolutely must pre-empt other running processes, there is a special security privilege to protect against haphazard use of it.

This is defined by the security policy. It works, for the most part, though is not perfect since the OS isn't designed for real-time operations. Microsoft considers this priority very dangerous, rightly so.

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. A keyboard is less of a priority than the real time process. This means the process will be taken into account faster then keyboard and if it can't handle that, then your keyboard is slowed.

Like all other answers before real time gives that program the utmost priority class. Nothing is processed until that program has been processed. On my pentium 4 machine I set minecraft to real time a lot since it increases the game performance a lot, and the system seems completely stable.

This prevents the threads of this process, which do not have high priority, from interfering with higher priority threads.

If a thread runs at the highest priority level for extended periods, other threads in the system will not get processor time. If several threads are set at high priority at the same time, the threads lose their effectiveness. The high-priority class should be reserved for threads that must respond to time-critical events. If your application performs one task that requires the high-priority class while the rest of its tasks are normal priority, use SetPriorityClass to raise the priority class of the application temporarily; then reduce it after the time-critical task has been completed.

Another strategy is to create a high-priority process that has all of its threads blocked most of the time, awakening threads only when critical tasks are needed.

The important point is that a high-priority thread should execute for a brief time, and only when it has time-critical work to perform. This class can be appropriate for applications that "talk" directly to hardware or that perform brief tasks that should have limited interruptions. This means that the thread priority is the same as the process priority class. After you create a thread, use the SetThreadPriority function to adjust its priority relative to other threads in the process.

However, if you have a thread waiting for another thread with a lower priority to complete some task, be sure to block the execution of the waiting high-priority thread. This is preferable to having the thread execute a loop.

Otherwise, the process may become deadlocked, because the thread with lower priority is never scheduled.
