Increasing the priority of a process will not normally improve it’s performance. If you have a CPU intensive program running it will normally be receiving virtually all of the CPU time already.

DO NOT, I repeat, DO NOT set the priority of such a program to Realtime. Many vital system processes run at a lower priority than this and they may not be able to run. This could create a lockup and require a reboot to regain control.

It is generally more useful to lower the priority of a CPU intensive process. This will increase the responsiveness of the system and impair the performance of the application only slightly.
