What's stopping you from creating multiple threads?

You can easily have a network thread and a UI thread and simply 
pass any data to the network thread from the UI thread and the 
other way around too using std.concurrency.

I've done that myself and it works fine and can definitely run at 
a faster FPS than 25 too.

Have you actually done any profiling that shows that D's GC is 
preventing you from achieving 25 FPS? 25 FPS is 40 ms, I don't 
know how much your update loop takes, but I don't think the D GC 
pauses would be this long?

Note also that it's also readily possible to architect a D app to 
use resource pools, reusable buffers, etc. such that GC cycles 
are never triggered.
