The reason I did not use LTO is because the GCC from default Fedora crashes Godot.
The releases of Godot custom patch gcc.
I didn't feel comfortable doing that.
What is the suggested method to install these runtimes?
* Visual Studio 2015 Runtime
* DirectX 9 Runtime
* DotNet Runtime
There could be a first run executable that executes the UE4Prerequisites installer (executes a random executable once).
