After the recent HW launch (nov. 2020) this seems like an ever more inevitable route. Missing eGPU support, portability > power, limited CPU resources and a cost/benefit ratio that is off the charts in a negative way as compared to other solutions unfortunately makes the platform less attractive.
As a cross-platform user it has annoyed me for years exactly how much more resources are available at a much, much lower price-point for PCs than what you get from Apple. The latest offerings didn't help.
I do get that most current Vuo users are Mac/Apple only, but I also would suspect a significant potential for expanding the user-base with a Windows port. From personal experiences, I can say that the more or less exclusive mac use for VJs at festivals in 2015 dropped fast, and that last year ('19) they were more or less extinct. I can't see this changing anytime soon.
Side note: I recently "upgraded" to macos 10.15, and so also xcode 12.1. Because of this, the default MacOs SDK is 10.15. This won't compile with that, but earlier SDKs can be found here: https://github.com/phracker/MacOSX-SDKs/releases. Download the required one (10.10) and place it in the folder specified in the CMakeLists.txt and it will compile.
