Flight sims and NPI: DLSS presets for MSFS 2024, DCS and X-Plane
NVIDIA already ships a Microsoft Flight Simulator 2024 profile that lists the Steam and Microsoft Store executables and package, so in NPI you edit that profile rather than adding an exe: enable the DLSS override and force a preset there. In VR the same profile should apply, because the sim renders DLSS, but we could not test it. We have no GPU, no cockpit captures and no headset, so no preset recommendation here is measured.
What this page can and cannot tell you
The brief for this page was cockpit comparisons, flight-replay frame costs and a VR test. Our lab has no NVIDIA GPU, no copy of any of these sims and no headset, so none of that exists. untested Preset results in the cockpit. What we can show is what NVIDIA’s own driver package says about these sims, which is useful because it answers the Store versus Steam question. LAB · driver 621.14 package
Steam vs Microsoft Store: the right exe
NVIDIA’s MSFS 2024 profile does not list one exe. It lists the main game, two families of build executables, with and without “steam” in the name, and a Microsoft Store package name. LAB · driver 621.14 package
| Entry | What it is |
|---|---|
flightsimulator2024.exe | The game executable, the same for both stores. |
kittyhawkx64_pcmbf, _pcr, _pcsub | Three build executables without "steam" in the name. We assume these are the non-Steam builds but NVIDIA does not say so. |
kittyhawkx64_steam_pcd, _pcmbf, _pcr, _pcsub | Four build executables with "steam" in the name. |
sunrisex64_pcd, _pcmbf, _pcr, _pcsub | A second family of four, without "steam" in the name. |
sunrisex64_steam_pcd, _pcmbf, _pcr, _pcsub | The same second family with "steam" in the name. |
microsoft.limitless_8wekyb3d8bbwe | A Microsoft Store package family name, not an exe. |
So both builds look covered by name. You do not add an exe: open the existing profile and change its rows. If a Store install still seems to ignore the profile, check the executable that actually runs in Task Manager against this list, using the add-a-game steps. We could not verify a Store install, so we do not claim the match works there. The sunrise and kittyhawk names are internal, so we do not interpret them beyond the steam marker.

The profile turns Resizable BAR on (↗ = 1).
LAB · driver 621.14 package The ReBAR page covers what that does. The older 2020 sim has its own profile, FlightSimulator.exe plus its Store packages, with nine settings and no ReBAR value.

Force a DLSS preset
The steps are the same as for any game: select the profile, enable ↗ (DLSS - Enable DLL Override), set ↗ (DLSS - Forced Preset Letter), apply and restart. The DLSS override page walks through it with screenshots, and the preset page explains the letters. We cannot say which preset reads glass cockpit text best, and no source we found tested it. Compare two presets yourself: set one, fly the same approach, change it, repeat. Check what is running with the DLSS indicator.
VR: per-game or global?
Untested: we have no headset. untested The reasoning is simple but unproven. DLSS runs inside the sim, which renders the eye images, so the sim’s own profile is the one that should matter, and the VR runtime only receives the result. Forum advice to use a global override exists, and its side effect is certain: a global override changes every game. Try the per-game profile first, and note that you can undo it in one step.
DCS World
NVIDIA’s profile for Digital Combat Simulator (listed under the name “Black Shark”) covers dcs.exe and sets four settings, all SLI-related.
LAB · driver 621.14 package It contains no DLSS or ReBAR value, so a DLSS override is a user change on top of it. We found no tested DLSS preset result for DCS and ran none.
X-Plane 12
NVIDIA lists x-plane.exe with four settings: a Quadro optimisation switch and OpenGL-related values.
LAB · driver 621.14 package Whether X-Plane 12 supports DLSS on 8 Nov 2026 is not something we verified, so check the sim’s own options before changing a profile.
NPI against DLSS Swapper for sims
DLSS Swapper replaces the DLL files in a game folder. NPI sets a driver-side override and touches no game files, which matters for a Store install where files are protected. Whether the swapper works on a Store-protected install is untested here. The tools comparison sets them side by side.
Recipes
No downloadable file: there is nothing we could verify. Everything above is a pointer to the profile NVIDIA already ships and the general override steps.
Undo
Reset ↗ and ↗ in the MSFS profile, or use the reset page. A global override, if you set one, is reset on the Global profile.
Questions people ask
Which DLSS preset is best for MSFS 2024 in VR?
We cannot say. We have no headset and no GPU, so we have no side-by-side captures. Use the preset guide for the general trade-offs and compare in your own headset.
Does the NPI profile work with the Microsoft Store version?
NVIDIA's profile for MSFS 2024 lists Store-build executables and a Microsoft.Limitless package name next to the Steam ones, so the driver intends to match both. We have not tested a Store install.
Should I use a global DLSS override for VR?
Not as a first step. A global override affects every game you launch, including ones that do not expect it. Start with the per-game profile and only go global if it demonstrably fails in your setup.
Can I use DLSS Swapper with MSFS 2024?
DLSS Swapper replaces files, while NPI sets a driver override. Whether a Store-protected install allows file replacement is something we have not tested; the driver override does not touch game files.
