A transparent window on top
The overlay is Visor's own window: transparent, above the game and click-through, so your mouse and keyboard stay entirely with the game.
In-game overlay · Pro
FPS over your game, without touching it
See FPS, 1% lows, frametime and CPU/GPU temperatures and load while you play, in a transparent, click-through window that stays on top. No DLL injection, no DirectX hooks, no reading game memory.
Try it free for 7 days in the app, no card needed.
How it works
Most overlays draw inside the game. Visor deliberately doesn't.
Frames from PresentMon
FPS and frametime come from PresentMon, an open-source tool that reads presentation events from Windows (ETW) rather than from the game, and works across graphics APIs.
No injection, hooks or memory reads
No DLL injection, no DirectX or Vulkan hooks, no opening or reading the game's memory. Game files are never touched.
The numbers that tell you if a game really runs smooth
- FPS: frames per second, right now
- 1% low: FPS in the worst 1% of moments, a far better stutter signal than the average
- Frametime graph: see a hitch the moment it happens
- CPU / GPU temperatures and load: which side is the bottleneck
- VRAM in use: whether your settings outgrow your card
A report after every session
Visor saves each session as a per-game report, so you can look back at temperatures, load and frame rates, compare before and after a settings change, and export to CSV for Excel.

Anti-cheat, straight talk
Anti-cheat systems look for programs that interfere with games: injected code, graphics hooks, memory reads. Visor does none of those things.
- The overlay is a separate window; it doesn't draw inside the game
- Frame data comes from Windows via PresentMon, not from the game
- Sensors are read from hardware through PawnIO, a signed driver, not the old WinRing0 driver some anti-cheat systems block
Even so, we can't guarantee what every game's developer decides. If a game gives you trouble, email us at [email protected] and we'll look into it.
Overlay questions
Does the overlay work with fullscreen games?
It works best with games set to Borderless or Windowed, the default for most games today. Some games in exclusive fullscreen may draw over the overlay window. If you can't see it, switch the game's display mode to Borderless.
Does the overlay lower my FPS?
The overlay draws a few numbers and a small graph in its own window and doesn't run inside the game. We built the whole app to stay under 2% CPU while updating every second, so it doesn't compete with your game for frames.
Is the overlay free?
The overlay is part of Visor Pro, a one-time US$2.99. You can try it free for 7 days in the app, no card needed.
What is PresentMon?
PresentMon is an open-source tool that reads Windows presentation events (Event Tracing for Windows, ETW) to measure FPS and frametime without going inside the game. Many performance tools use the same approach.
