- Remove promoted map entirely — processes are demoted when RSS < -mem and promoted when RSS >= -mem, no permanent state - Remove trySetPrio closure — use setPrio directly for simplicity - Remove curPrioWithHandle helper — inline procGetPriority.Call - Remove GAME ... tracked as game (blocked) repeated log — log once on detection via GAME DETECT, silently skip on subsequent scans - Game mode: log GAME DETECT once when process first exceeds game-mem - gameSaved stores original priority before IDLE demote, restores on GAME MODE OFF or shutdown - Delay between priority changes: 100ms - Delete TZ.md (was a test for other AI)
autoPriority
Monitors process memory usage on Windows and automatically adjusts CPU priority: promotes memory-heavy processes to HIGH and demotes everything else to NORMAL. Optionally enters Game Mode when a process exceeds a higher threshold, boosting it to HIGH and setting all other processes to IDLE.
Windows only.
How it works
Normal mode
Every scan interval the program iterates over all running processes:
RSS vs -mem |
Current priority | Action |
|---|---|---|
| ≥ threshold | anything except HIGH | → HIGH (logged as PROMOTE) |
| ≥ threshold | already HIGH | skip |
| < threshold | ABOVE_NORMAL, HIGH, or REALTIME | → NORMAL (logged as DEMOTE) |
| < threshold | NORMAL, BELOW_NORMAL, or IDLE | skip |
Game mode (-game-mem)
When any process reaches or exceeds the -game-mem threshold:
- That process → HIGH (logged as
GAME) - All other processes → IDLE
- Log:
GAME MODE ON
When all such processes close:
- All processes that were demoted during game mode are restored to their original priority (logged as
RESTORE) GAME MODE OFFlogged- Normal mode resumes — priorities recalculated by
-memrules
If SetPriorityClass or OpenProcess fails for a process (e.g., anti-cheat protection, system processes), the process is added to an in-memory exclusion list and never touched again (logged as BLOCK). When the process exits, it is automatically removed from the list.
On shutdown, all processes are restored: game-mode demoted processes to their saved original priority, promoted and game processes to NORMAL.
Build
Requires Go 1.26+.
# Standard build (with console window)
go build -o autopriority.exe .
# Background build (no console, minimal size)
go build -ldflags="-H windowsgui -s -w" -o autopriority.exe .
Usage
autopriority [flags]
| Flag | Default | Description |
|---|---|---|
-mem |
512M | Memory threshold (e.g. 512M, 1G, 2048M) |
-game-mem |
4G | Game threshold (e.g. 3G, 4G). Must be > -mem. 0 = disabled |
-interval |
1 minute | Scan interval (min 10s) |
-dry-run |
false | Log only, don't change priority |
Examples:
# Run with 1 GB threshold, scanning every 30 seconds
autopriority -mem=1G -interval=30s
# Run with defaults (512M threshold, 4G game threshold)
autopriority
# Game mode: normal threshold 512M, game threshold 4G
autopriority -mem=512M -game-mem=4G
# Dry run — log decisions without changing anything
autopriority -dry-run
Log
Log is always written to %TEMP%\autopriority.log. A new log file is created on each run (previous log is deleted).
Log entries:
| Prefix | Meaning |
|---|---|
PROMOTE |
Priority raised to HIGH (normal mode) |
DEMOTE |
Priority lowered to NORMAL (normal mode) |
GAME |
Process set to HIGH or IDLE (game mode) |
GAME MODE ON |
Game mode activated |
GAME MODE OFF |
Game mode deactivated — processes restored |
BLOCK |
OpenProcess or SetPriorityClass failed; process added to exclusion list |
RESTORE |
Process restored to original/saved priority (game mode exit or shutdown) |
SKIP RESTORE |
PID reused by a different process; restore skipped |
[DRY-RUN] |
Would change priority (dry-run mode) |
Auto-start
Open Win+R, type shell:startup, and press Enter. Then place a shortcut to autopriority.exe in the folder that opens.
Dependencies
None. Uses only Windows API (kernel32, psapi) via raw syscall.
