Best MSFS 2024 graphics settings for an RTX 5090 at 4K, including DLAA, DLSS, Frame Generation, LOD, traffic and stutter fixes.
For an RTX 5090, start MSFS 2024 at 4K with DirectX 12, Ultra as the base, DLAA for the cleanest cockpit image, Frame Generation on, Terrain LOD 200, Objects LOD 200, Ultra textures and clouds, and 100% render scaling. Lower traffic and LOD first when performance drops; the GPU is rarely the only limit.
Recommended RTX 5090 settings for MSFS 2024
The best balanced profile uses Ultra selectively rather than pushing every slider to its maximum. An RTX 5090 has ample graphics performance and VRAM, but busy airports, detailed airliners and dense traffic can still overload the simulator's main thread.
| Setting | Recommended value | When to change it |
|---|---|---|
| Display resolution | Native 4K | Use the monitor's native resolution; avoid external upscaling on top of DLSS. |
| DirectX | DirectX 12 | Required for the modern NVIDIA feature set. |
| Global quality | Ultra, then customise | Ultra is a suitable starting point, not the final configuration. |
| Anti-aliasing | DLAA | Change to DLSS Quality when chasing a higher base frame rate. |
| Render scaling | 100% | Leave at 100 with DLAA. Raising it above 100 has a poor performance-to-image-quality return at 4K. |
| Frame Generation | On | Turn it off temporarily when diagnosing stutters or measuring native performance. |
| NVIDIA Reflex | On, if available | Keep enabled when using Frame Generation. |
| Terrain Level of Detail | 200 | Use 150 at complex hubs or 250-300 over rural scenery if the main thread has headroom. |
| Objects Level of Detail | 200 | Reduce to 150 before lowering texture quality. |
| Texture Resolution | Ultra | Leave on Ultra unless troubleshooting an add-on or memory issue. |
| Anisotropic Filtering | 16x | Keep at 16x; the performance cost on this GPU is negligible. |
| Volumetric Clouds | Ultra | Drop to High in heavy weather if the GPU becomes the limit. |
| Buildings and trees | Ultra | Reduce only after LOD and traffic have been adjusted. |
| Grass and bushes | High or Ultra | High is sensible around dense airports; Ultra suits low-level VFR flying. |
| Shadows | High | Ultra shadows provide limited benefit in normal cockpit use. |
| Ray-traced shadows | High, if offered | Lower or disable this before reducing textures or terrain detail. |
| Ambient occlusion and reflections | High | Use Ultra only when GPU headroom is plentiful. |
| Glass Cockpit Refresh Rate | High | Use Medium in complex airliners if the main thread is overloaded. |
| Motion blur and depth of field | Off | These are preference effects and can reduce instrument clarity. |
DLAA gives glass displays, runway markings and distant geometry the cleanest appearance at native 4K. DLSS Quality is the better choice for high-refresh monitors, demanding weather or unusually heavy scenery. Our comparison of DLAA and the DLSS quality modes explains when each option makes sense.
Should Frame Generation be enabled on an RTX 5090?
Frame Generation should normally be enabled, provided the simulator already maintains a stable native frame rate. It improves camera and panning fluidity but does not remove main-thread stalls, scenery-streaming pauses or the latency of a low base frame rate.
Enable the simulator's supported Frame Generation option rather than stacking unrelated scaling tools. If it is missing or greyed out, check DirectX 12, the graphics driver and Windows requirements using our Frame Generation setup procedure for MSFS 2024.
A mistake we see constantly is judging performance only by the generated frame-rate number. Switch Frame Generation off while tuning, establish a smooth base frame rate, then turn it back on. This exposes genuine CPU or streaming problems that generated frames can temporarily disguise.
Why can MSFS 2024 still stutter with an RTX 5090?
An RTX 5090 cannot overcome a main-thread bottleneck. Large airports, detailed avionics, high Terrain LOD and dense aircraft or ground traffic can saturate the CPU while the graphics card waits for work.
Use the simulator's performance display and watch the limiting status:
- If it reports
Limited by MainThread, reduce Terrain LOD, Objects LOD, airport activity, road traffic and AI or live aircraft. Lowering render resolution will not solve this condition. - If it reports a GPU limitation, change DLAA to DLSS Quality, lower ray-traced shadows, clouds, ambient occlusion and reflections, in that order.
- If neither component remains consistently saturated, inspect scenery add-ons, background programs and scenery-streaming consistency rather than cutting every graphics setting.
Our CPU-versus-GPU performance diagnosis covers the limiting indicators and the appropriate fixes in more detail.
What should be lowered first at demanding airports?
Reduce CPU-heavy settings before sacrificing cockpit sharpness or texture detail. This order preserves most of the RTX 5090's visual advantage:
- Traffic and airport activity: Use moderate aircraft, worker and vehicle densities. Traffic is often more expensive than its visual contribution suggests.
- Terrain LOD: Move from 200 to 150 at a complex hub. Values above 200 are best reserved for less demanding areas.
- Objects LOD: Reduce from 200 to 150 if detailed terminal buildings still cause main-thread pressure.
- Glass cockpit refresh: Change High to Medium in avionics-heavy aircraft.
- GPU effects: If the GPU is actually limiting performance, lower ray-traced shadows, clouds, reflections and ambient occlusion before textures.
- Upscaling: Change DLAA to DLSS Quality last. This produces a large GPU saving without the softness of more aggressive DLSS modes.
Do these settings change at 1440p or 8K?
At 1440p, use DLAA and expect the CPU to become the limit sooner. A lower resolution does not justify maximum Terrain LOD or unlimited traffic because those settings remain heavily dependent on the processor.
At 8K, begin with DLSS Quality and move to Balanced if weather, shadows or complex scenery overload the GPU. DLSS Performance is a fallback rather than the default; its lower internal resolution can make glass displays, fine text and distant structures less stable.
For G-Sync, V-Sync, frame caps and driver-level filtering, use one coherent configuration rather than stacking multiple limiters. Our recommended NVIDIA Control Panel profile for MSFS sets out the combinations that avoid unnecessary latency and frame-pacing conflicts.
