MSFS 2024 Sim Update 6 beta: DLSS 4.5, FSR 4, and the graphics settings that changed

Sim Update 6 opened as a public beta on July 6, 2026 as build 1.8.5.0. The headline is upscaling: DLSS 4.5 becomes the default native upscaler, AMD gets FSR 4, and there is Dynamic Frame Generation with in-game VSync. This is what changed and how to configure it without chasing invented benchmark numbers.

Bottom line

Sim Update 6 beta (build 1.8.5.0, July 6, 2026) adds DLSS 4.5 as the default upscaler, FSR 4 for AMD, and Dynamic Frame Generation with in-game VSync. The FSR menu is now a simple on or off, with the version set by your GPU driver. It is a beta, so opt in deliberately and know the rollback path before you install.

What changed in Sim Update 6 beta

This build is mostly a rendering and upscaling update, with quality-of-life and VR fixes alongside. These are the confirmed changes from the beta release notes.

  • DLSS 4.5 support, now used as the default native upscaler.
  • Dynamic Frame Generation with in-game VSync support.
  • FSR 4 for AMD, with the settings menu simplified to on or off and the version chosen by your GPU driver.
  • An option to start a flight without the walkaround in Free Flight, under assistance settings.
  • Fixes for cockpit texture and LOD popping, distant shadow rendering, and LOD-transition flicker.
  • VR improvements, especially PlayStation VR2, with better central clarity, better performance, and lower memory use.

How to set up the new upscaling

The goal is smooth frame times over a big headline number. Start conservative and only add frame generation once your base frame rate is healthy.

  • On NVIDIA RTX, select DLSS and a quality preset that keeps your base frame rate comfortably above your monitor's refresh before enabling frame generation.
  • On AMD, the menu only exposes FSR on or off; the actual FSR 4 path depends on a current GPU driver, so update the driver first.
  • Enable Dynamic Frame Generation only when your base frame rate is stable, since frame generation amplifies stutter if the base is already choppy.
  • Because Dynamic Frame Generation now supports in-game VSync, use the in-sim VSync option rather than forcing VSync in the driver to avoid conflicts.

Beta bugs, platforms, and rollback

This is opt-in beta software. Know the platforms it covers and how to leave before you install over a stable setup.

  • Platforms: the beta is available on Windows PC, Steam, Xbox Series X and S, and PlayStation 5.
  • Treat add-on compatibility as unverified until each developer confirms Sim Update 6 support; beta builds can break third-party aircraft and scenery.
  • Rollback on Steam: opt out of the beta branch in the game's properties, then let it revert to the stable build.
  • Rollback on Xbox and the Microsoft Store: leave the beta or flight in the client and reinstall the retail build.
  • Back up your community folder before installing so add-ons are easy to restore after a rollback.

A note on performance claims

FrameReady does not publish benchmark numbers it has not measured, and independent Sim Update 6 testing is still ongoing.

  • DLSS 4.5, FSR 4, and frame generation change image quality and smoothness differently on every GPU and scenery load.
  • Any specific FPS figure you see this early is a single reviewer's sample, not a settled result.
  • The reliable move is to test your own busy scenario, a complex airport at a demanding time of day, and compare frame times before and after.
  • We will add measured comparisons once the beta stabilises and repeatable results are available.
