Features

• Custom crosshair builder with shape, size, thickness, gap, color, opacity, and outline controls.
• Profile workflow for switching quickly between games or setups.
• Visibility presets for high-contrast crosshairs.
• Optional performance overlay with Off, Minimal, and Detailed modes.
• Frame Cap Assistant for target-FPS guidance.
• Supported NVIDIA per-app profile controls and AMD-related display/color paths.
• Multi-monitor and DPI-aware overlay behavior.
• Non-injected design with no game hooks.

---

What's New in v1.7.0

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

---

Requirements

• Windows 10 or Windows 11.
• .NET 8 Windows Desktop Runtime for framework-dependent builds.
• Borderless windowed or windowed game mode is recommended for overlay visibility.

---

Limitations & Safety

• LightCrosshair does not inject into games and does not use game hooks.
• 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 pacing diagnostics use conservative heuristics, ETW-style present telemetry analysis, and optional RTSS fallback paths; PresentMon integration remains a future target and is not implemented as a live runtime backend.
• Frame-generation and DLSS runtime control are not implemented.
• NVIDIA profile writes are per-app only where supported; LightCrosshair does not write global NVIDIA profiles.
• Some games or anti-cheat systems may block overlays or behave differently.
