puremode-override

FiveM sv_pureLevel client-side override with a modern Win32 GUI.

Scans the running FiveM game process for the sv_pureLevel global across every non-system module, writes the chosen value to every instance and holds them with a persistent guard that re-writes every 100 ms — so the game never sees a non--1 value regardless of which internal code path checks it.

Preview

• Custom borderless window (drag-to-move, minimize / close)
• Dark purple palette, gradient title bar, real-time log
• Numeric input with - sign support, defaults to -1
• Single APPLY button; the guard arms automatically on a successful write

Build

Requirements:

• Windows 10 / 11 x64
• Visual Studio 2022 (v143 toolset)
• Windows 10 SDK

Create an empty Windows Desktop Application project targeting Release | x64, drop the source files in, and set the following in project properties:

C/C++

• Language / C++ Language Standard → stdcpplatest
• Code Generation / Runtime Library → Multi-threaded (/MT)
• Code Generation / Security Check → Disabled (/GS-)
• Code Generation / Control Flow Guard → false
• Code Generation / Spectre Mitigation → Disabled
• General / Warning Level → Turn Off All Warnings (/W0)
• Preprocessor Definitions: NDEBUG;_WINDOWS;_MBCS;_CRT_SECURE_NO_WARNINGS;WIN32_LEAN_AND_MEAN
• General / Debug Information Format → None
• General / Additional Include Directories → $(ProjectDir)

Linker

• System / SubSystem → Windows
• Debugging / Generate Debug Info → false
• Manifest File / UAC Execution Level → requireAdministrator
• Input / Additional Dependencies: kernel32.lib;user32.lib;gdi32.lib;msimg32.lib;shell32.lib

General

• Character Set → Multi-Byte
• Output Directory → $(ProjectDir)bin\
• Intermediate Directory → $(ProjectDir)bin\int\

Build. Output lands at bin\pure-mode-override.exe.

Usage

1. Launch FiveM and reach the server list / connecting screen.
2. Run pure-mode-override.exe (as administrator).
3. The tool waits for the FiveM game window, resolves every target across the loaded modules and reports Ready.
4. Leave the field at -1 (or type 0), press APPLY.
5. On success the log shows Applied and the persistent guard keeps the value in place until you close the tool.

Layout

No external dependencies. Pure Win32 + GDI, C++ latest, single-file per module.
