How do I reduce VRAM usage in MSFS 2024?

Reduce VRAM usage in MSFS 2024 by changing the right graphics settings, measuring dedicated memory and isolating heavy aircraft or scenery add-ons.
Adam McEnroe

To reduce VRAM usage in Microsoft Flight Simulator 2024, lower Texture Resolution first, then reduce render resolution or Render Scaling, Off-Screen Terrain Pre-Caching, and Terrain/Object Level of Detail. Disable memory-heavy airport, aircraft and livery add-ons. Change one setting at a time and test at the same demanding airport.

Which MSFS 2024 settings reduce VRAM the most?

Texture Resolution is usually the most effective setting because detailed aircraft, cockpit and scenery textures consume substantial dedicated GPU memory. Lower it by one step, restart the simulator for a clean comparison, and inspect cockpit labels and nearby buildings before reducing it again.

Setting or changeLikely VRAM effectMain compromise
Texture ResolutionUsually largeSofter cockpit, aircraft and scenery textures
Display resolution or Render ScalingModerate to large at high resolutionsReduced image sharpness
Off-Screen Terrain Pre-CachingModerate and scene-dependentMore pop-in or hitching when turning the camera
Terrain and Objects Level of DetailModerate in complex areasLess detail and shorter object draw distances
Traffic density and model varietyScene-dependentFewer aircraft, vehicles or airport objects
Clouds, shadow maps, reflections and ambient occlusionUsually secondaryLess convincing weather, lighting and reflections

Start with the controls at the top of the table rather than setting everything to Low. Our graphics-setting breakdown for MSFS 2020 and 2024 explains the wider visual and performance trade-offs.

A low-VRAM tuning order that preserves image quality

The reliable method is to reproduce the same demanding flight and remove one source of memory pressure at a time. An empty rural airfield is a poor test if the problem normally appears in an airliner at a detailed international airport.

  1. Create a repeatable baseline. Load the aircraft, airport, weather and cockpit view that trigger the problem. Record dedicated GPU memory and watch for stutters while panning the camera.
  2. Test without add-ons. Use a stock aircraft and airport, or temporarily disable suspected scenery, aircraft and traffic packages. If usage falls sharply, changing global graphics settings would only conceal the real cause.
  3. Lower Texture Resolution one step. Restart MSFS 2024 and repeat the same camera movements. Keep the lower setting if memory use and frame pacing improve without unacceptable cockpit blur.
  4. Reduce Render Scaling gradually. This reduces render-target memory and GPU load. Avoid a large drop unless the GPU is operating at a very high output resolution.
  5. Trim scenery retention and detail. Lower Off-Screen Terrain Pre-Caching, Terrain Level of Detail and Objects Level of Detail in small steps. If camera rotation starts producing pop-in or pauses, restore pre-caching and reduce LOD instead.
  6. Adjust secondary settings last. Reduce clouds, shadows, reflections and traffic only if the main changes do not leave enough headroom for arrival at a dense airport.

If the memory reduction does not improve frame times, VRAM may not be the limiting factor. Use our broader frame-rate and bottleneck checks to distinguish GPU memory pressure from main-thread, system RAM, streaming and graphics-load problems.

How can I tell whether VRAM is actually the problem?

VRAM pressure is likely when dedicated GPU memory stays near its limit, shared GPU memory rises sharply, and severe stutters appear as new scenery or cockpit views load. Windows Task Manager can show dedicated and shared GPU memory; a graphics-driver overlay can provide the same distinction if one is installed.

  • A high dedicated-memory reading alone is not proof of a fault. MSFS 2024 can use spare memory for resources and caching.
  • Texture degradation, long pauses while panning and problems concentrated at detailed airports strengthen the diagnosis.
  • A crash to desktop does not by itself prove VRAM exhaustion. Drivers, add-ons, system RAM, overclocks and damaged packages can produce similar symptoms.
  • Integrated graphics use shared system memory, so the usual dedicated-VRAM limit is less meaningful, although lower textures, resolution and LOD still help.

There is no universal safe percentage because the operating system, display resolution, aircraft and scenery all affect the required headroom. Test the departure and arrival, not merely the initial loading screen.

Do DLSS and Frame Generation reduce VRAM?

DLSS or another upscaler can reduce memory used by high-resolution render targets, but it does not shrink every aircraft and scenery texture. It may therefore produce a smaller VRAM saving than lowering Texture Resolution, especially when a detailed add-on airport is the main problem.

Frame Generation should not be treated as a VRAM fix. It can improve displayed frame rate, but generating intermediate frames requires additional resources and does not increase the GPU's texture capacity.

VR has a separate memory burden

VR headsets render high-resolution views for both eyes, so Render Scaling and Texture Resolution become especially significant. Tune the VR graphics profile separately and use our dedicated MSFS 2024 VR tuning workflow before sacrificing cockpit readability.

Add-on aircraft and scenery can exceed the VRAM budget

High-resolution airport textures, detailed airliner cockpits, large livery textures and varied AI traffic models can combine to exceed a GPU's capacity even when each package works correctly by itself. Overlapping airport enhancements are a common failure mode because both products may load resources for the same location.

Simply having many liveries installed does not mean all their textures are loaded. Concentrate on the aircraft, nearby traffic and scenery active in the problem flight. Compare the route with a stock aircraft and airport, then re-enable packages individually until the increase returns.

Will a larger page file or rolling cache help?

No: neither the Windows page file nor the MSFS rolling cache adds dedicated VRAM. The page file supports system memory and commit capacity, while the rolling cache stores streamed scenery data on disk. Enlarging or deleting either one does not correct an oversized GPU texture workload.

Shared GPU memory can keep an application running after dedicated memory fills, but transferring resources through system RAM is much slower and may cause hitching. If MSFS 2024 continues to crash after VRAM use has been reduced, follow our separate crash troubleshooting steps rather than assuming every crash is a graphics-memory failure.

Granular VRAM monitoring and graphics tuning apply mainly to PC. Consoles manage their unified memory automatically and expose fewer controls, so add-on isolation and selecting an available performance-oriented preset are the practical options there.
