Okay BFG10K, I installed the game and patched it with the full 1.4 patch (~180MB's or something) and launched the game.
First, it automatically detects your system and adjusts accordingly. However, when making settings in the Video options menu before the game launches there is no option for any type of HDR.
Then, upon entering the game I browse the in-game settings and video options only to find that there still isn't any in-game option for HDR. Once the game starts to play, I quickly discover that my mouse doesn't move my character in any fashion nor make the guy look in any direction. Basically, while in game my mouse did absolutely nothing. Although when I hit Esc and can move it all around and click on every thing that is in the game menu. I've never had a game do that, not even BF2.
So, I walk only being able to face ONE direction until I find a good beam of light through the cracked roof (the one by the skeleton on the steps) and bring up the console just to see if HDR can still be forced.
The first attempt didn't do anything, so I put the "DEVMODE" command through it following with the normal r_HDRRendering # command and it once again failed to do anything.
After restarting my computer several times and checking and re-checking the driver options, I went to Tweakguides to hear what they might have about the new patch. Turns out they mention others have been having a lot of issues with it as well and recommend on just keeping the 1.33. Basically, the 1.4 was only good for the multiplayer from the sounds of it and the whole thought of adding non-consoled support for the HDR+AA went down the hole.
