This is a game I've been working on in my copious free time. Its a RTT with
you controlling upto 8 tanks at the same time.
The engine renders around 2.5 MTris/sec (100 Fps) on a Geforce 2 MX. Things
I've added recently that didnt make it into the pics are terrain scarring
and procedural creation of small rocks (a la Sacrifice).
The landscape is a heightfield using ROAM. I'm considering replacing ROAM
with a quadtree algorithm as that is more hardware TnL friendly.
