Any way to get source games to switch engines?

I have both versions of the source engine (the original one used one HL2 and the orange box engine) but the original engine is comparatively crap in relation to the orange box engine and also doesn't recieve updates (the AA setting doesn't work, there are texture glitches etc.).

Seeing as I have both engines, would it be possible for me to force it to use the newer engine through the launch settings or a config file or something like that? The original engine is really playing up now and I thin it should be possible, no?

Edit: Also, on another note, I run TF2 at 720p, when I quit it breifly goes back to 1080p but then decides that it would actually rather run in 720p instead. Then I hsvr to right click on the catalyst icon snd switch res, it claims it's running at 1080p so I have to switch it to ome other resolution first to make it see sense, then when I switch back to 1080p it's actually 1080*1920 like ti should be. Is this a common problem, if so is there a known fix?

 

I don't have these issues with the old source engine, but im quite positive that you can't just switch it around...

 

I am surprised all source games have not moved to the newer version. Surely Valve would not find that too difficult.

 

I'm no game engineer, but I can't imagine it's that easy.

They're working on overhauling Counter-Strike: Source to the newer rendition of the Source engine right now; in fact it's in closed beta as we speak.

 

Well, it is not like you just use the 'new' version. There are compatibility issues as the 'new' version is not simply added lines in the code but some re-work in the code itself. Thus it is necessary to check everything the game use to do its done properly (rendering, fx, etc.).

 

So you can't just tell the orange box engine to run the original levels? I'd have thought it would use the same file types and textures.

What is really odd is that for some reason lost coast is using the old engine, even though I got it as part of the orange box. The resolutiong change problem seems to happen to all non native resolution source games.

 

CS Source is getting updated to the newer source engine I think. That's why there's a big update for the game (in beta right now).

I don't know about HL2 though.
