Help Me With the HDR Please...

[Mithin]

I Only have a day ago that I have to buy Half-Life 2, everything is totally normal, until it reaches the Black Mesa East chapter, where all the lighting goes full, the details, we completely removed the atmosphere, the feeling is not really something that makes it playable but it is to be a cancer to the eyes as I searched Steam forums, Post Internet, and nothing the only thing is to type codes console mat_dxlevel90, mat_hdr_level 2 mat_hdr_enabled_, mat_dxlevel mat_fullbright 0 and 80 but still to go to another section of a loading screen looks awful again and pass that to the game every time you win the gifted, AGAIN, over and over and over again, is a complete headache ... please help ...
