Should You Set Games to High Priority in Task Manager?
Published
On this page
Setting a game to High priority in Task Manager only helps when your CPU is the bottleneck and heavy background tasks are competing for it — on an otherwise idle system it does almost nothing. Priority doesn’t create CPU power; it only decides who wins CPU time when processes fight over it. This guide covers when High actually helps, why Realtime is a trap, and what to do instead for a real, lasting gain.
What process priority actually does
Windows shares your CPU across every running process using a scheduler. Priority is the tiebreaker the scheduler uses when more threads want the CPU than there are cores to run them. A Normal process and a High process both run fine when there’s spare capacity; the difference only appears under contention — when something else is also hammering the CPU.
That’s the whole reason the tweak is hit-or-miss: if the game already gets all the CPU it asks for, promoting it to High gives it nothing extra.
When High priority actually helps
| Scenario | Does High priority help? | Why |
|---|---|---|
| Game alone, GPU-bound | No | GPU is the limit; CPU has headroom to spare |
| Game alone, idle system | Barely | Nothing is competing for the CPU |
| Streaming / recording (OBS on the same PC) | Sometimes | Encoder and game contend for CPU cores |
| Heavy background load (browser, downloads, RGB/launcher bloat) | Sometimes | Priority lets the game win the contention |
| CPU-bound competitive shooter, 1% lows dipping | Sometimes | Smoother frame pacing when threads compete |
The pattern: High priority is a contention tool. It smooths 1% lows and frame pacing under load far more than it moves average FPS, and it does nothing on a clean, GPU-limited system.
How to set game priority to High
- Launch the game, then alt-tab out (use exclusive Fullscreen so alt-tab is clean).
- Open Task Manager (Ctrl+Shift+Esc) → Details tab.
- Right-click the game’s
.exe→ Set priority → High. - Confirm the prompt.
This resets to Normal every time the game restarts. To make it stick, use a shortcut with start /high "" "GamePath.exe", the game’s launch options, or a rule tool like Process Lasso that reapplies your saved priority automatically.
Never use Realtime
Realtime sits above critical Windows threads — input, audio, disk, and network services. A game at Realtime can starve them, producing input freezes, audio crackle, hitching, or a full system lock. It does not give more FPS than High. There is no competitive reason to use it; High is the ceiling worth touching for a game.
The better fix: remove the contention
Because priority only matters under contention, the bigger win is to remove the contention instead of re-ranking it:
- Close Chrome/Edge tabs — each is a CPU-using process.
- Quit RGB software, launchers, and updater agents (Armoury Crate, iCUE, GeForce Experience overlays you don’t need).
- Disable Discord hardware acceleration/overlay if you don’t use it in-game.
- Turn off Xbox Game Bar and background recording — see disable Xbox Game Bar and Game DVR for FPS.
Removing background load helps average FPS, 1% lows, and input latency at once — priority only ever helps the second of those, and only under load.
Priority vs. CPU affinity — don’t confuse them
Two different knobs live in the same right-click menu:
- Priority — who wins CPU time under contention (this guide).
- Affinity — which cores a process is allowed to run on.
Manually restricting affinity usually hurts modern games, which are built to spread across all cores and use Windows’ thread director on hybrid (P-core/E-core) CPUs. Leave affinity on All processors unless you’re troubleshooting a specific old title.
The honest verdict
- Idle, GPU-bound system: don’t bother — High changes nothing measurable.
- Streaming, recording, or a cluttered background: try High, watch your 1% lows, and keep it if frame pacing improves.
- Always: close background load first — it beats any priority tweak.
- Never: Realtime.
Priority is a legitimate tool for the CPU-contended case, but it’s a scalpel, not a magic FPS button. For a bottleneck-free system, the input-latency wins come from elsewhere — timer resolution, Reflex, and an FPS cap.

Frequently asked questions
Should you set a game to High priority in Task Manager?
Only if you're CPU-bound and running heavy background tasks at the same time — then High priority can smooth 1% lows by letting the game win CPU time. On an otherwise idle system it changes almost nothing, because the game already gets the CPU it asks for. High is safe to try; the real gains come from closing background load, not from the priority flag itself. Never use Realtime priority.
Does High priority increase FPS?
Rarely on average FPS, and only when the CPU is the bottleneck and other processes are competing for it. Priority controls who gets the CPU when there's contention — if your GPU is the limit, or the CPU has spare headroom, raising priority gives the game nothing it wasn't already getting. Where it can help is 1% lows and frame pacing while recording, streaming, or with a browser full of tabs open.
Why should you never use Realtime priority for games?
Realtime priority lets a process outrank even critical Windows system threads — keyboard, mouse, audio, and disk I/O. A game set to Realtime can starve those services, causing stutters, input freezes, audio dropouts, or a hard lock. High is the highest priority worth using for a game; Realtime does not give more FPS and routinely makes the system worse.
Does game priority reset when you close the game?
Yes. Priority set through Task Manager or Details is per-process and resets to Normal every time the game restarts. To make it persistent you need a launch wrapper (a shortcut using 'start /high'), a tool like Process Lasso that reapplies a saved rule, or the game's own launch options. For most players the effort isn't worth it versus simply closing background apps.
Is closing background apps better than raising game priority?
Almost always, yes. Raising priority just changes who wins CPU time during contention; closing the background load removes the contention altogether, which helps average FPS, 1% lows, and input latency at once. Shut down Chrome tabs, Discord overlays you don't need, RGB software, and launchers before playing — that beats any priority tweak on a normal system.
