Re: [Flightgear-devel] Unreal Engine 5 and Antoinette Project

Flightgear can look amazing when you use the HDR pipeline. We absolutely
need this to stay relevant. The problem is that HDR is not compatible
with OpenGL1 PUI. Work on getting rid of PUI has been going on for over
a decade (longer than it took to implement it), and I wonder if it
wouldn't be better to just break compatibility. I am sure that someone
will update the few good aircrafts to a new standard. Do we even need a
GUI? You also don't have it in real live.
The next big problem is GC stuttering. It is mainly a problem of Nasal
because unlike any other sane scripting language, it stores local
variables on the heap and not on the stack. Not sure if there is a way
to change that.
