When there will not be graphic issues, fps issues, texture issues and so on, I do not care about compatibility with fsx. I will buy another better looking and optimized addons. I hope Captain sim will make addons for Flight in future too.

The worst part about the release of a new version of Flight Sim, is the learning of the new creation method required. That's why it can take a while for the next generation addons to make an appearance.
