Windows Task Manager lets you change how much CPU attention a program gets by setting its process priority. Bumping a game to High priority tells the scheduler to service it ahead of background tasks, which can shave stutters when other apps are competing for the processor. It is a small, sometimes useful tweak, but one that is easy to misuse, so here is how to do it correctly and when it actually helps.
What priority does and does not do
Priority controls the order in which the CPU scheduler hands out time slices when there is contention. If nothing else is demanding the CPU, raising a game’s priority changes nothing, because it already gets everything it needs. The benefit appears when background processes like a browser, an antivirus scan, or a download are fighting the game for cycles; a higher priority keeps the game ahead of them.
| Priority level | Effect | Recommendation |
|---|---|---|
| Normal | Default balance | Fine for most |
| Above Normal | Slight edge over background | Safe to try |
| High | Strong preference for the game | Use with care |
| Realtime | Can starve the OS | Avoid |
Set priority step by step
Through Task Manager
Launch the game, alt-tab out, open Task Manager, and go to the Details tab. Right-click the game’s executable, hover Set Priority, and choose Above Normal or High. The change applies instantly and lasts until you close the game. Test with a frame-time overlay while a background task runs so you can see whether stutter actually improves.
Never use Realtime
Realtime priority sits above many operating system processes and can starve input, audio, and networking, making the whole PC unresponsive. It rarely helps games and often hurts. Stick to Above Normal or High if you use this feature at all.
Make it persist
Because Task Manager priority resets each launch, use a launcher script if you want it applied automatically. A command using start /high or start /abovenormal to launch the game executable applies the level from the start. Some third-party tools can also watch for a game process and reassign priority automatically, which is handy if you always game with other apps open.
Better first steps than priority
Before relying on priority, close the background apps causing contention in the first place. Ending a heavy browser session or pausing a download does more than nudging priority, because it removes the competition entirely. Priority is a patch for when you must keep those apps running, not a substitute for a clean gaming environment. Combining a High priority with reduced background load gives the smoothest result.
Combine priority with efficiency-mode for background apps
Windows 11 adds an “Efficiency mode” you can toggle per process in Task Manager, which nudges a background app onto efficiency cores and lower priority. Rather than only raising the game, you can lower the competition: set Efficiency mode on a browser or updater so it yields to the game automatically. This two-sided approach, a modest boost for the game plus a leash on background apps, is gentler than forcing the game to High and less likely to cause side effects. It also survives better in practice because you are cooperating with the scheduler’s design instead of overriding it, keeping the whole system responsive while the game gets first call on the CPU.
FAQ
Does High priority increase FPS?
Not on its own if the CPU has spare capacity, because the game already runs unimpeded. Where it helps is reducing stutter when background processes are competing for the CPU; the game gets serviced first, so frame times stay steadier. With nothing else running, expect little to no change.
Is it safe to set a game to High priority?
Above Normal and High are generally safe and reversible; they simply prefer the game during contention. Avoid Realtime, which can outrank essential system processes and freeze input and audio. If anything feels off, priority resets automatically when you close the game.
Confirm the gain with a repeatable test
Priority changes are subtle, so measure rather than trust a feeling. Run the same demanding scene twice, once at Normal and once at High, with a background download active and a frame-time overlay on screen. Compare the 1 percent lows and the frequency of hitches, not just the average frame rate. If the numbers barely move, the CPU had spare capacity and priority was not your bottleneck, so put your effort into closing background apps or upgrading hardware instead.
Bottom line
Process priority is a niche tool for keeping a game responsive when other apps hog the CPU. Set Above Normal or High from Task Manager’s Details tab, never Realtime, and make it stick with a launch script if needed. For the best result, first close the background tasks causing contention, then let a higher priority handle whatever is left.
