Portal 2 also looks decent, graphics wise).
No, you are talking about GoldSrc, the engine they used for the original Half-Life; that one was a heavily modified Quake Engine.
Source is their own development. Sure, might contain bits here and there, but then again, all do. But it's a different thing altogether.
They will probably release the next episode with a revamped Source Engine. DX9 must still be present, because of the installed user base, and probably DX11 support. They can probably jump DX10 at this time in my opinion.
The best DX9 can surely satisfy most who have a DX10 card, with the bonus of working in XP.
Having said that, Source has been continually improved. The best demonstration of that is Left 4 Dead 2. Just look at some of the chapters with all those rain and light effects. And they have been working on facial animation too. But because the game is so much action packed, few took the time to admire the work they did with that game. So, yes, with more improvements they will have a top notch DX9 engine and are probably working on a DX11 engine right now.
When Half-Life 2 came out they were one of the first to use DX9 and the game looked beautiful. They even had HDR working back in 2003. The only reason it didn't ship with the game was because they still hadn't figured out a way to make it work together with Anti-Aliasing. They eventually did in 2005 and released the Lost Coast Demo.
So, when Ep 3 comes out, it will probably be a showcase of what DX11 can do. I bet they wouldn't do it for less at this time. I don't expect it at least until late this year, but probably only in a year's time.Edited by tpi2007 - 2/21/11 at 4:33pm
