A process running at a higher priority will get more resources than lower priority tasks, but it will only get those resources if it needs them-so a high or realtime priority process that's not doing anything won't bog down your system.Ī quick primer, for the uninitiated. Most processes launch at 'normal' priority, which means the OS will treat them relatively equally. Windows has six priorities: low, below normal, normal, above normal, high, and realtime. All running processes on your PC have a different priority level.

It's called multi-tasking, and we're all familiar with the concept by now. Windows does all of this already, and it has been doing so for decades. Game Mode in theory works best when you don't take such measures and simply let the OS handle the dirty work. But that's if I'm doing my normal thing while playing games: I close any unnecessary applications sitting in the background and basically free up resources so that the game will run as well as possible. In most cases, the changes are small and would go unnoticed. Turns out, the simple answer is that it's not substantially different from what I saw before.
