    ✈️ AeroTuneMFS — Intelligent Performance Optimization & System Health Platform for MSFS 2020 & 2024

    AeroTuneMFS is a lightweight, AI-assisted performance companion for Microsoft Flight Simulator. It runs alongside the simulator and continuously adjusts key graphics settings such as Terrain LOD (TLOD), Object LOD (OLOD), Cloud Quality, and Shadow Quality in real time — keeping your flight smooth and stable without constant manual tweaking.

    Now in v1.1.0, AeroTune expands beyond real-time tuning with the introduction of System Health reports, performance analytics, and graph-based insights via the new Pro platform.

    Unlike simple FPS-based tools, AeroTune reacts to actual system load, VRAM pressure, altitude, AGL (above ground level), and flight phase (ground, climb, cruise, approach). The result is more consistent performance where it matters most: takeoff, approach, and busy airport environments.

    ⭐ Key Features

    Core Engine (Free)

    • Real-time dynamic tuning of TLOD, OLOD, Clouds, and Shadows
    • Altitude-aware tuning with High-Altitude TLOD Boost
    • Low-AGL safety guard for stable approaches
    • Independent OLOD mode for better object detail control
    • Optional ML-based stutter detection
    • Emergency VRAM protection with smooth recovery
    • Built-in Calibration Wizard (quick 3-minute setup)
    • Multi-backend GPU telemetry (NVML, DXGI, ADLX, etc.)
    • Lightweight overlay with live tuning feedback
    • Automatic updates (stable & beta channels)

    🆕 Pro Platform (v1.1.0)

    • System Health reports with performance breakdowns
    • Graph-based analytics (CPU, GPU, VRAM, stability trends)
    • Session history & performance insights
    • Smarter diagnostics and bottleneck detection
    • Future advanced analysis tools (expanding platform)

    🧠 How It Works

    AeroTune does not chase FPS numbers.

    Instead, it:

    • Monitors CPU, GPU, RAM, and VRAM load
    • Detects instability and stutters
    • Applies small, reversible tuning steps
    • Learns your system’s stable limits over time (ML calibration)
    • Avoids changes during low-altitude and unstable phases

    This conservative approach keeps visuals smooth without aggressive oscillation or visual “popping.”

    📦 Installation

    Download and run the installer (close MSFS first)
    Follow the setup wizard (default path recommended)
    Launch Microsoft Flight Simulator
    Start AeroTuneMFS
    Right-click the tray icon to access features

    ⚠ For memory-write features (TLOD/OLOD/Cloud/Shadow tuning), run AeroTune as Administrator.

    🔑 First Run & Activation

    AeroTuneMFS includes a free core experience.

    On first launch, you’ll activate with a free API key to enable:
    • Secure memory detection
    • Updates and platform features

    Optional: Upgrade to Pro to unlock System Health reports and advanced analytics.

    🛠 Troubleshooting

    • “Waiting for Microsoft Flight Simulator…” → normal if MSFS isn’t running
    • GPU/VRAM shows 0% → switch telemetry backend in tray
    • Dynamic Settings ON → recommended OFF to avoid conflicts
    • High VRAM → AeroTune will automatically reduce load temporarily
    • OLOD not changing → memory address may not yet be detected

    ⚠️ Due to how MSFS manages memory, some settings (OLOD, Clouds, Shadows) may not always be available. AeroTune will safely continue with available controls.

    🚀 Coming Soon: AeroTune v1.1.1

    ✨ What’s New:
    CPU / Render Thread Smoothing (NEW!): AeroTune can now detect when you are CPU or render-thread limited. It will gently reduce TLOD to smooth out spikes and improve consistency.

    Keep an eye out for: “Smoothing render thread — reducing TLOD slightly”

    Auto-Start: AeroTune can now automatically launch and attach with MSFS for a more seamless startup experience.

    Smarter VRAM Handling: Better detection of VRAM saturation with improved behavior when you're approaching your hardware limits.

    🔧 Fixes & Optimizations:
    OLOD Max Enforcement: OLOD limits are now treated as a hard cap, preventing values from exceeding your configured max.

    VR & Multi-Screen Stability: More stable tuning under heavy rendering loads—especially helpful for high-resolution setups.

    Memory Detection Updates: Continued improvements to reliability and compatibility across various sim builds.

    General Stability: Internal tweaks for more consistent optimization behavior.

    This update will be hitting Pro users for early testing very soon.

    Does this work with MSFS24 SU5 BETA

    26 days ago

    Hi! I haven't officially completed my own suite of tests on SU5 yet, but I know several users are already running AeroTune with SU5.

    29 days ago

    Not sure if this has already been mentioned but I notice that when I set a TLOD parameter (100-200) and save those changes, the next time I open Aerotune it resets this to 20-100 for me without a notice. Am I missing something? I would prefer not to have to override this setting with each start up :)

    29 days ago

    In beta v1.1.1.3 this has been improved. AeroTune now uses preset/profile-based limits (instead of silently resetting values), so any TLOD range you set is now tied to an active profile rather than being overridden on startup.

    Greetings, I'm writing to express my gratitude. As a first-time user, I have only compliments. This optimizer is undeniably the best I've ever used. Despite having a lower-end RTX 4060 and Ryzen 7 5700x, it keeps my MSFS sessions stable, which is why I continue to play. Keep up the great work!

    Really appreciate you taking the time to say that, thank you! It's exactly what AeroTune was built for - More improvements on the way!

    What is the TLOD value in Live Screen? I have my range set 125 to 250, but TLOD always shows less than 100?

    about 2 months ago

    That value on the Live Screen is the current live TLOD AeroTune is actively applying, not your configured range. Your 125–250 is just the allowed range — AeroTune will drop below it if needed to protect performance (usually VRAM or stutter risk).

    Hello. How can I autostart your app with MSFS? I use msfs autostart to start different software but your app doesnt start with it. And would be perfect if app and cmd window starts minimized to tray. As autofps does. That's very inconvinient to start aerotune every time manually and have 2 additional app windows in system panel.

    about 2 months ago

    Hi — AeroTune doesn’t currently have a proper “start with MSFS and launch straight to tray” workflow like AutoFPS, which is why external auto-start tools may not behave as expected with it. I agree it would be a much better experience, especially avoiding the extra app/CMD windows, and it’s something I’m looking to improve.

    The new uptate v1.1.0 works PERFECT. Great work. Thank You. Very much.

    Very glad to hear and thank you!

    I tried, and unfortunately after couple of mins of checking it, I had to go back to AutoFPS. The main problem I had when using the software that I didn't have before was when panning the camera down/up to check the efb on the A2A Comanche there is a huge stutter and that for me is a no no as Im checking the EFB map when flying VFR. I will leave 4 starts to the app, seems great, and I hope the ML model improves and gets better. Definitívy in the future I will give it another try

    2 months ago

    Thanks for trying AeroTune and for the feedback. The stutter when panning the camera definitely isn’t something AeroTune should introduce. The current live version is the stable release, but I'm actively improving the tuning logic and behaviour in the beta builds, which often include adjustments and improvements before they reach the main version. If you’re open to it, it might be worth joining the beta and giving it another try there, as updates are happening more frequently. Thanks again for the 4 stars and the constructive feedback.

    I have to say this as developer myself, it's SUSPICIOUS having this tool force you to use any sort of KEY/CODE and running background process to the cloud. Even if there aren't any hiddent intentions here, a developer knows any connection to the cloud is a vulnerability. So, is why is that risk necessary for a tool that is meant to optimize locally/not interact with the internet?

    Very suspicious really...

    [Edit] ----------
    The Dev answered, I appreaciate your non-defensive response, the explanation is welcome.
    cheers

    AeroTune itself does all optimisation locally on your machine. The tuning logic, telemetry analysis, and the actual adjustments to things like TLOD, clouds, shadows, etc. are not cloud-driven and do not depend on an internet connection to function.

    The API key is simply used for a few platform features around the application ecosystem, such as:
    * licensing/activation
    * beta access management
    * optional features like health report (from v1.1.0+) uploads or support diagnostics

    Those checks are lightweight and periodic — they’re not part of the optimisation engine itself. If the connection isn’t available, AeroTune will still run locally and continue monitoring and optimising the sim.

    You’re also absolutely right that any internet connection introduces a theoretical attack surface, which is why the communication is limited to a small set of endpoints and only exchanges minimal data needed for those services.

    So the key isn’t there because the optimiser needs the cloud — it’s there because AeroTune is distributed as a managed application with beta access, updates, and optional services, rather than a completely standalone script.

    Totally understand the concern though — it’s a reasonable thing to question when looking at any software that communicates externally.

    Hi, I have a question. I also have AutoFps, and there is a file of autofps installed in the community folder. Its name is Mobi flight event module. That file needs to be installed to run AutoFps. It automatically installs in your community folder when u install autofps. But my question is, does that file have an effect on aerotunemfs? Can that file create a conflict even if i only run aerotunemfs? I dont run autofps and aerotunemfs at the same time.

    Kind regards

    Hi! The Mobiflight Event Module that AutoFPS installs in the Community folder won’t affect AeroTune if AutoFPS itself isn’t running.

    AeroTune doesn’t rely on that module and it communicates with the sim in its own way, so having the Mobiflight module present in the Community folder won’t interfere with AeroTune.

    Conflicts would only really happen if two optimisation tools were running at the same time and both trying to change things like TLOD or other settings.
