Did you read through or overviewed this thread ?
You will find many many screenshots from golden_boy,
showing exactly what FTE is able to do.
You will see the skyboxes, you will even get links to pages
with tons of skyboxes you can choose from.
You will see the nice alias shadows.
You will also find useful cvars from gb, which improves several things.
well, my config is almost identical to gbīs.
Except I use Bloom, gb doesnt. I dont use realtime light
because its not perfect yet. Just as you said.
This is something no other H2 engine has. FTE team sure will work on it to enhance it.
What you see in DarkPlaces is not comparable to FTE yet.
But we will see what comes... I have good confidence.
In my opinion, everything what is needed is available in FTE.
The very luxurious things are not perfect yet, but at least are available too.
Biggest advantage: Its updated continuously...!
(and the programmers are nice people)
