Pretty darn smooth! So far I've been only been able to trigger the real-time shadows by firing rockets around and watching the resulting explosion cast shadows... but yeah it's working. Don't you have a test map or something that better demonstrates the new features?
Perhaps a map with light sources that cast shadows all the time? Maybe some moving light sources to demonstrate real-time shadows?
Besides shadows, what else is in? With this new lighting system, I take it you are now also lighting model polyons properly (per vertex)?
It runs super smooth on my ATI 4870 X2 at 1600 x 1200.
Now if only someone would fix the sound code so it sounds a lot more like ZDoom's and I might consider permanently switching to Vavoom...
EDIT: Just tried it with models. WHOA SHIT, it ran like ASS! Like, less than 1 FPS. More like, 1 frame every 5 seconds. There was even one time when there were 4 zombiemen in front of me and they all started firing (thus casting shadows all over the place) and Vavoom froze and I had to Ctrl-Alt-Del.
The shadowing looks nice though. The models all seem to cast self shadows as well.
Why is it so slow though? :/ I'm using the latest ATI Catalyst drivers and all of the settings are at factory defaults (so there's nothing like forced AA turned on or anything like that).
Changing to a lower resolution doesn't solve the problem. It still runs SLOW when models and real-time shadows are turned on. Without models, it's pretty smooth though.
