Gizmo64 LTS: is this $10 stack worth it for Gaming?

If you fly the X-Aviation CL650 in X-Plane, you know the specific pain of a plugin that was built for a previous generation of hardware and software. The original Gizmo64 was the backbone of that experience, but as X-Aviation pivoted to new tech and Apple pushed the ARM transition, the old setup started to crack. Frame drops, Rosetta 2 overhead, and nagging license dialogs became the price of admission for a smooth flight. Gizmo64 LTS is the patch for that exact moment. It’s not a new simulator; it’s a critical update that keeps your current X-Plane 11 or 12 setup running natively on modern Macs and Windows, specifically targeting the stability issues that have been plaguing long-haul simmers.

Quick answer

If you’re running a MacBook Pro with an M-series chip and tired of the translation layer, check the Gizmo64 LTS installation notes to see if your setup qualifies.

What you’re actually buying

You aren’t buying a new aircraft or a scenery pack. You are buying a stability and performance patch for the Gizmo64 plugin, which is the engine room for X-Aviation’s complex cockpits. At $10, this is a no-brainer if you are currently experiencing the “heavy CPU usage or frame drops” that the listing explicitly flags as a common issue for CL650 users. The core value here is the Apple Silicon (ARM) native support. If you are on a Mac, this update means you no longer need Rosetta 2 to run the plugin, which translates to better battery life, lower thermal throttling, and generally smoother frame times.

The package also includes a serial number that removes the nag dialog from the free version. This is a small quality-of-life upgrade, but it matters when you are in a long session and don’t want a pop-up interrupting your pre-flight checks. The plugin is designed to be a drop-in replacement for the version X-Aviation is currently shipping, meaning it should work seamlessly with other X-Aviation offerings like the CL650. It’s a focused, niche tool that solves a very specific technical problem: keeping a beloved, complex cockpit simulation running efficiently on modern hardware. (Gizmo64 LTS)

One buyer highlighted the exact benefit of the ARM support: “Works great with Macbook Pro Max M3 Arm native, no Rosetta 2 needed any more to fly X-Aviation CL650. Thanks Ben! 🙏” Gumroad reviews

Why it’s on our radar

This update is interesting because it addresses a “sunset” scenario. X-Aviation is moving toward a different technology path, which means the old Gizmo64 infrastructure could have been left to rot. Instead, Ben Russell has maintained and updated it, ensuring it remains compatible with both X-Plane 11 and the newer X-Plane 12. For simmers who have invested in the X-Aviation ecosystem, this is a way to extend the life of their current setup without jumping to a potentially unproven new tech stack. (Gizmo64 LTS)

The specificity of the bug fixes is also a strong signal. It’s not just a “performance improvement”; it’s a fix for the “imgui assert bug,” a fix for the “compare number to nil” error in offline play, and a fix for the hidden license activation window on multi-monitor setups. These are the kinds of granular issues that make or break a simulation session. If you are a multi-monitor user or someone who flies offline, these fixes alone justify the $10 price tag.

What actually matters

Before you buy, you need to check your specific aircraft and software version. The listing is clear that this plugin has NOT been tested with IXEG Classic Plus or the DC3 version 2. If you are flying those specific aircraft, this update might not be the right solution, and you should proceed with caution. (Gizmo64 LTS)

• Backup your current plugin: The installation instructions are straightforward but require you to rename your existing Gizmo64.plugin to backup_Gizmo64.plugin and delete the X-Aviation.plugin if you have it. This is a manual process, so make sure you follow the steps in the Gizmo64 LTS download guide carefully to avoid breaking your current setup.
• Hardware compatibility: If you are on an Intel Mac or Windows, the plugin will still work, but the headline benefit of native ARM support won’t apply to you. You will still get the bug fixes and the nag removal, but the performance boost will be less dramatic than for Apple Silicon users. (Gizmo64 LTS)
• Version compatibility: Confirm you are running X-Plane 11 or 12. The plugin is built for these versions and is not intended for older X-Plane releases. (Gizmo64 LTS)

FAQ

Does Gizmo64 LTS work with X-Plane 12? Yes, the plugin is explicitly compatible with both X-Plane 11 and X-Plane 12. It is designed to be a drop-in replacement for the current X-Aviation shipping version, so it should integrate smoothly with your existing X-Plane 12 installation.

Can I use the serial number on multiple computers? Yes, the serial number is not machine-id locked. You can use the same serial number as many times as you like, which is a significant perk for simmers who fly on different machines or build new rigs frequently. (Gizmo64 LTS)

Is this update required to fly X-Aviation aircraft? No, the update is not strictly required. However, it is highly recommended if you are experiencing performance issues, frame drops, or if you are using an Apple Silicon Mac. It provides a convenience and improvement that makes the simulation experience much smoother. (Gizmo64 LTS)

Bottom line

Gizmo64 LTS is a small, targeted fix that delivers a big quality-of-life improvement for X-Plane users. For $10, you get native ARM support, critical bug fixes, and a cleaner interface without nag dialogs. If you are flying the CL650 or other X-Aviation aircraft on a modern Mac, this is an easy recommendation. Just make sure you aren’t using IXEG Classic Plus or DC3 v2, and follow the installation steps carefully.
