GTA San Andreas Fixer

A lightweight Windows console utility that helps stabilize GTA San Andreas (gta_sa.exe) by:

• Raising process priority to reduce stutter.
• Optionally trimming memory usage when it grows too high.
• Detecting real freezes (Not Responding) and only then force-closing the game.

Why this exists

Some systems experience:

• lag spikes,
• long frame hitches,
• the game hanging and never recovering.

This tool continuously monitors the game process and applies safe optimizations while avoiding false freeze kills.

Features

• ✅ Watches for gta_sa.exe.
• ✅ Boosts process priority to High.
• ✅ Detects freeze using consecutive not-responding checks.
• ✅ Closes game only after freeze threshold is reached.
• ✅ Optional memory trim (EmptyWorkingSet) to reduce spikes.
• ✅ Configurable via appsettings.json.

Build

dotnet build

Run

dotnet run --project src/GtaFixer.App

Publish as .exe (Windows)

dotnet publish src/GtaFixer.App -c Release -r win-x64 --self-contained false /p:PublishSingleFile=true

Published binary will be in:

src/GtaFixer.App/bin/Release/net8.0-windows/win-x64/publish/

Configuration

Edit src/GtaFixer.App/appsettings.json:

• ProcessName: default gta_sa
• PollIntervalSeconds: how often checks run
• FreezeThresholdSeconds: how long app must remain not responding before kill
• EnableMemoryTrim: whether memory trim is enabled
• MemoryTrimThresholdMb: trim when above this working set

Notes

• Run this fixer before launching GTA SA, or while the game is running.
• Freeze kill logic only triggers when the process is repeatedly not responding.
• If your game uses a different executable name, change ProcessName.
