Gaming Mode

OLED Guard Pro is designed to keep working inside borderless fullscreen games — the mode most modern PC games run in. Two factory presets, Gaming — Fast and Gaming — Slow, are tuned for the two ends of the gaming spectrum.

The two gaming presets

Gaming — Fast

Tuned for multiplayer and esports: short accumulation window, quick decay, low maximum dim. Picks up new static HUDs quickly but never gets in the way of a fast-paced scene.

  • High capture FPS so transient HUD flashes register
  • Low dim cap so dark scenes (caves, night maps) stay clean
  • High dynamism gate — only the most persistent static regions get protected

Gaming — Slow

Tuned for cinematic single-player RPGs: longer accumulation, slower decay, higher dim ceiling. Tolerant of long static menus and cutscenes.

  • Lower capture FPS — fine for content that moves slowly
  • Higher dim cap for the long static map screens common in this genre
  • Lower dynamism gate — more permissive about what counts as static

Both presets ship with Auto Mode on, the Morphological noise-gap filter, and High quality preset.

Setting up a gaming session

  1. Open the dashboard and navigate to the Overlay page
  2. Pick Gaming — Fast or Gaming — Slow from the preset list
  3. (Optional) Set up an App Profile so the right preset loads automatically when your game becomes the foreground window — see App Profiles

Fullscreen compatibility

  • Borderless fullscreen — fully supported. The overlay composites on top of the game through DWM, with no swap-chain interference.
  • Exclusive (legacy) fullscreen — the engine detects DXGI occlusion, pauses rendering to save GPU and power, and resumes automatically when you alt-tab out.
  • Multi-monitor gaming — each display has its own pipeline, so your side monitors stay protected while you game on the primary.
  • HDR / G-Sync / FreeSync — all work; the overlay is a DWM-composited layer rather than a swap-chain hook.

Ignore Active Window

If you don't want any overlay on the game window itself — useful for screenshot purity or when the overlay is just visible enough to bother you in dark scenes — turn on Ignore Active Window. Protection on every other monitor continues normally; the foreground game gets passed through untouched.

This setting is on by default in the productivity presets and off in both gaming presets.

Performance impact

The hot path runs entirely on the GPU:

  • Capture uses DXGI Desktop Duplication (hardware-accelerated)
  • Per-pixel exposure modelling and the overlay shader both run as compute / pixel shaders
  • Quality presets (Low / Medium / High / Ultra) let you trade detection resolution against frame budget

In typical use, less than 1% GPU overhead measured in real benchmarks. The cost is paid in parallel with your game's render, not in serial.

Hotkeys worth knowing while gaming

  • Ctrl+Shift+O — toggle protection on/off without leaving the game
  • Ctrl+Shift+− / Ctrl+Shift+= — nudge protection intensity down/up
  • Ctrl+Shift+H — toggle the heatmap visualisation
  • Ctrl+Shift+V — toggle vignette edge protection

All hotkeys are configurable from the Hotkeys page.
