X-Aviation and Gizmo

[ColinM9991]

Hi there,

I've owned several products from the X-Aviation store for a few years and have recently installed some again since Gizmo is now on the way out. I have some observations and feedback regarding the user experience of the newer plugin.

With the IXEG having not received an update in a number of years, it's understandable that it still depends on Gizmo. However, the installer of the CitationJet 525 (downloaded the latest installer as of 27th Feb 2026) automatically removes Gizmo which isn't a great user experience as any updates that run through the installer will knock out Gizmo, requiring manual intervention every time.

Process:

1. Install IXEG 737
2. Verify that Gizmo64.plugin exists under Resources\plugins
3. Install C525
4. Observe that Resources\plugins\Gizmo64.plugin is automatically removed (no prompt or confirmation)

Can this behaviour be removed from the installer or at least have the user prompted as to whether they wish to remove Gizmo64?

The second point around the X-Aviation plugin is that it comes with a massive performance hit when the activation window is opened. Here's a screenshot from X-Plane's microprofiler which shows that an overwhelming majority of the frame time is spent on XPDDrawSingleWindowHook. This reduces my FPS from 120FPS to a whopping ~25FPS

The obvious solution is to close the activation window once all is activated. However, as Gizmo64 was quite a problematic plugin in that it would cause problems for many SASL and XLua based aircraft, I thought it best to raise this too in case there's any downstream impact later into the flight. I've never seen a plugin cause such a reduction in FPS by drawing a UI.

This has always been the case since day one of the transition.

Hi Cameron, thanks for getting back to me.

Somebody in the HotStart Discord mentioned this, but this isn't the case on Windows - at least not for the installer that I downloaded for the TorqueSim CitationJet 525. That explicitly removes Gizmo without any prompt.

I double and triple checked to make sure I wasn't haphazardly clicking "Next".

Is there another installer that I should be using?
