Any way to force disable VSync and use exclusive fullscreen on Windows?

Hi! I’m currently developing a very precision-based platformer where the input delay is critical. And i’m having issues with that, because GDevelop uses borderless fullscreen(which is basically windowed mode but with hidden window borders) instead of exclusive fullscreen, and Windows forces VSync on every windowed mode app, which introduces a slight input delay. As I understand, Electron(the framework whick GDevelop uses for desktop game builds) doesn’t support both exclusive fullscreen mode and disabling vsync.

Are there any workaround for this? Are there any Electron alternatives that support exclusive mode fullscreen and have an option to disable vsync?

Unfortunately, as far as I know, the answer is no.

All alternatives I can find are either based on Chromium (like electron) or the OS webview. Neither support exclusive fullscreen mode, nor do they have a way to reliavly disable their native forced vsync. (Edit: looks like Chromium used to have a flag you can use, but it stopped working a few years back)
