Not that I've seen, only option I noticed was for turning off the textures which is the part of it I'm fine with and it still leaves the models even then.You know you can turn off the atrocious new character models in the settings, right? HDTP is primarily about items/weapons/scenery.
Edit: WELL SON OF A BITCH, I'm completely blind. Loaded the fucker up to double check and noticed the big honking HDTP options button which I somehow glossed over every time, possibly because I was looking for it under the graphical options which does has disabling the textures for HDTP under graphics rather than the HDTP options. Shame I'm only seeing this now I'm at fucking Vandenberg but thanks for the heads up at least, that'll make subsequent plays a lot more palatable.
