Great show; glad to see it continuing. I've been listening to these guys for a while, and I look forward to each episode still.
Ultimate++ is a project as an IDE with a GUI Creator and a library (faster replacement for much of STL) with many additional helpful libraries that make C++ development so much smoother. http://ultimatepp.org/ Check out their forums as they are very active. I would download the latest SVN build from here: http://code.google.com/p/upp-mirror/downloads/list
"...it looks exactly same with the PPU as it does without it, the only difference is you get the extra blocks/debris, the strange thing is these extra blocks/debris seem to appear unrealistically out of no where when you shot things like the wall, floor etc, it really is like they've just been tacked on just to say *this game supports PhysX*." I definitely agree. I thought the PhysX acceleration in GRAW was not a full implementation at all.
