Any way to use 16xQ CSAA in HL2 Original Campaign?

[Leto Atreides II]

I'm playing the original Half Life 2 campaign again for the first time since I upgraded my computer, and it seems that Episode One has a 16xQ CSAA anti-aliasing option that looks much better than the 4x MSAA (NVIDIA doesn't support 6x) that seems to be the best option in the original HL2. Is there any way to force 16xQ CSAA in the original HL2? I could not locate the relevant lines in config.cfg and trying to force it via the NVIDIA driver does not work.

You can try running the HL2 maps in the Episode 2 engine by copying some files around. The details are out there, just google it. You will also get the Episode 2 flashlight, maybe even motion blur.

This method has bugs though.
