Specific objects appear to lack textures wrapped around the models. escalators and scientists on the Title/ main menu screen show as glowing “colors” [usually white], while most objects render properly. (Screenshot Imgur album here ==> https://imgur.com/a/rRw8K/ ).
Due to Dual Graphic card setup, Game configured to force graphics processing from Nvidia GeForce GTX 660M. attempts to use “-dxlevel ##” [##'s attempted = 90,95,98] caused game to register different directx versions yet yielded no results in altered performance, better nor worse. update drivers for integrated Intel and Nvidia card provided no effect, neither positive or negative.
problems existed constant with occasional proper rendering of face’s and hands [as seen in linked image album]. problem persisted beyond first, second and third level load points along tram path. problem continued throughout lab in acquisition of “hazard suit”. game session ended by author, at this point, and save file discarded.

Final notes:
Game only runs under “compatibility mode” with operating system selection from “win xp service pack 3” to “windows 7” allowing function. not running under compatibility mode causes game to fail after “blurred menu Loading screen” with text “hl2.exe has stopped working” dialog.
