As with HL-2 the engine runs suprising well.
I use the same launch and in-game settings as I do in HL-2. Map load times are easily on par with native speed.

As with HL-2 sound is perfect. Framerates appear marginally faster but could still be an issue. I will update this post after I've gotten a few days of playtime under my belt while using CW.
