The main settings to turn off in Overwatch for less lag are V-Sync, Triple Buffering, Dynamic Render Scale, Ambient Occlusion, Local Reflections, and Dynamic Reflections. Lowering Shadow Detail and Effects Detail to Low also helps, and enabling Reduce Buffering can improve input feel on many setups.

Best settings to disable

  • V-Sync: Off. It adds latency.
  • Triple Buffering: Off. It can increase input delay.
  • Dynamic Render Scale: Off. It can cause inconsistent performance.
  • Ambient Occlusion: Off. It is a common FPS-heavy option.
  • Local Reflections: Off.
  • Dynamic Reflections: Off.
  • Local Fog Detail: Low or Off if available.

Lower these too

  • Shadow Detail: Low.
  • Effects Detail: Low.
  • Texture Filtering Quality: Medium or lower if your PC is struggling.
  • Model Detail: Lower it if you still get stutters.

Helpful extras

  • Set the game to fullscreen.
  • Turn FPS limits off or raise them enough to match your monitor setup.
  • Close background apps and launchers before playing.
  • Use Reduce Buffering if the option is available in your version of Overwatch.

Simple preset

If you want the fastest quick fix, use this: Low shadows, Low effects, reflections off, ambient occlusion off, V-Sync off, triple buffering off, dynamic render scale off, fullscreen on. That is the most common “less lag” combo from the guides I found.

TL;DR: Turn off V-Sync, Triple Buffering, Dynamic Render Scale, Ambient Occlusion, Local Reflections, and Dynamic Reflections; then drop Shadows and Effects to Low.
