Overview

LightCrosshair is a lightweight crosshair overlay for Windows 10/11, designed for players who want a simple, customizable, and non-invasive overlay for borderless or windowed games.

It focuses on the essentials: a visible crosshair, profile-based configuration, quick hotkeys, optional performance information, and a design that avoids game injection or hook-based backends.

Features

Custom crosshair overlay with configurable shape, size, thickness, gap, color, opacity, and outline.
Profile workflow for switching quickly between different games or visibility needs.
Visibility presets for high-contrast setups without changing in-game rendering.
Optional performance overlay with Off, Minimal, and Detailed display modes.
GPU driver integration for supported NVIDIA and AMD-related display/color features.
Frame Cap Assistant for target-FPS guidance.
Non-injected design: no game hooks, no injection, and no native runtime backend.
Borderless/windowed friendly for better overlay visibility.

What's New in v1.7.0

Fixed NVIDIA FPS cap profile binding so per-app cap controls target the selected application profile.
Added NVIDIA profile audit information for safer inspection before applying supported per-app settings.
Added NVIDIA Low Latency Off/On per-app controls.
Added NVIDIA VSync per-app controls.
Added read-only NVIDIA G-SYNC and Low Latency CPL State display.
Kept NVIDIA safety boundaries: no global profile writes, no raw setting editor, no DLSS writes, no G-SYNC writes, and the app remains asInvoker.

Limitations & Safety

LightCrosshair does not inject into games.
Exclusive fullscreen can hide normal overlays; use borderless windowed or windowed mode when possible.
Frame Cap Assistant provides guidance only and does not enforce a real FPS cap.
Frame-generation and pacing diagnostics currently use conservative heuristics, ETW-style present telemetry analysis, and optional RTSS fallback paths where available. Full PresentMon integration remains a future target and is not advertised as an implemented live runtime backend yet.
Some games or anti-cheat systems may block overlays or behave differently.
No overlay can guarantee universal compatibility with every game.
