MSFS 2020 DLSS 4 explained: supported RTX features, exact NVIDIA app and in-sim setup, hardware limits, and fixes for missing options.
MSFS 2020 has no native “DLSS 4” menu, but its PC version can use DLSS 4 features through NVIDIA’s driver-level overrides. Enable DLSS in the simulator, then select the available DLSS overrides in the NVIDIA app. RTX 50 cards are required for Multi Frame Generation; older RTX cards get fewer features.
Which DLSS 4 features work in MSFS 2020?
DLSS 4 is a collection of technologies rather than one setting, so support depends on the graphics card and driver profile. The simulator’s menu continues to say NVIDIA DLSS or Frame Generation; it does not change to “DLSS 4”.
| GPU | DLSS Super Resolution override | Frame Generation |
|---|---|---|
| GeForce RTX 20/30 series | Newer transformer-based model where offered | Not supported |
| GeForce RTX 40 series | Newer transformer-based model where offered | Regular Frame Generation; no Multi Frame Generation |
| GeForce RTX 50 series | Newer transformer-based model | Multi Frame Generation through the NVIDIA app profile |
Ray Reconstruction is not relevant because MSFS 2020 does not use the ray-traced effects that require it. Xbox consoles cannot use NVIDIA DLSS or NVIDIA app overrides.
How do I enable DLSS 4 in MSFS 2020?
- Install a compatible NVIDIA driver and NVIDIA app. The driver package must include the DLSS override controls.
- Enable Hardware-accelerated GPU scheduling. This Windows setting is required for Frame Generation. Restart the PC after changing it.
- Select DirectX 12 in MSFS 2020. Open the simulator’s graphics options, change the DirectX version to DX12 and restart the simulator. Frame Generation will not work under DX11; our MSFS 2020 DX11 and DX12 comparison explains the trade-offs.
- Turn on DLSS. In the graphics settings, set anti-aliasing to NVIDIA DLSS and begin with Quality mode. Enable NVIDIA DLSS Frame Generation as well if the option is available for your card.
- Close MSFS 2020. Driver overrides should be changed while the simulator is not running.
- Open the Microsoft Flight Simulator profile in the NVIDIA app. Go to its graphics or programme settings and select Microsoft Flight Simulator. If it is missing, add the simulator’s installation location to the app’s scan locations and scan again.
- Choose the DLSS overrides. Set the model-preset override to the newest available model. On an RTX 50 card, select the desired Frame Generation multiplier if the profile offers 2X, 3X or 4X options.
- Apply the settings and launch MSFS 2020. Recheck that DLSS and Frame Generation remain enabled in the simulator.

Why is the DLSS override missing or greyed out?
A missing override usually means the hardware, driver or detected game profile does not meet that feature’s requirements.
- No NVIDIA app profile: launch MSFS 2020 once, close it and run the NVIDIA app’s game scan again.
- No Multi Frame Generation option: MFG requires an RTX 50-series GPU. RTX 40 cards can use regular Frame Generation but cannot generate multiple intermediate frames.
- Frame Generation unavailable in MSFS: confirm that DX12 and Hardware-accelerated GPU scheduling are enabled, then restart both Windows and the simulator.
- Override marked unsupported: the installed driver/profile combination is not exposing that feature. Updating the NVIDIA software and rescanning the game is safer than manually replacing DLSS DLL files.
- Settings appear to do nothing: remove conflicting global NVIDIA settings and configure DLSS through the per-game Microsoft Flight Simulator profile.
Which DLSS and Multi Frame Generation settings should I use?
Start with DLSS Quality and regular 2X Frame Generation, then increase the multiplier only if the underlying frame rate is already stable. Multi Frame Generation raises displayed FPS, but it does not make the flight model, main thread or controls run three or four times faster.
At 1080p, DLAA can produce clearer cockpit displays when GPU headroom permits. At 1440p or 4K, DLSS Quality is the sensible starting point; Balanced or Performance modes are mainly for cases where the GPU remains the limiting factor. Our recommended MSFS 2020 DLSS settings by resolution and workload cover those choices without confusing Super Resolution with Frame Generation.
If MSFS is stuttering because the main thread is overloaded, reduce CPU-heavy options such as Terrain Level of Detail before raising the frame-generation multiplier. Generated frames cannot repair pauses in the base rendering cadence and may make cockpit artefacts or control latency more noticeable.
How can I confirm that DLSS 4 is active?
Check that the Microsoft Flight Simulator profile in the NVIDIA app shows the selected overrides, then use NVIDIA’s performance overlay to compare the displayed frame rate with Frame Generation on and off. The MSFS Developer Mode FPS counter can report the simulator’s rendered frames rather than every generated frame, so it may not show the full displayed-frame increase.
