I play the game and try different settings but as far as I can tell there is no change to graphics in game. This seems to be the case whether I have DX11 enabled or not, and whether I have high-res textures available or not.
Strangely, it does have a huge effect on my FPS - on all "high" settings, I get over 60FPS pretty much constantly. On all "ultra" settings I slow down to approx 20-30 FPS. Still looks the same though...
I'm usually pretty sensitive to differences and remember being able to tell the difference between high / gamer / extreme or whatever the original options were, so pretty sure it's not just me.
I've also noticed that in the console I get a lot of red error messages about various commands not being registered. It's like the game is trying to execute commands to change graphics settings but not being able to find them.
If it's relevant, I am using the Steam version of the game, confirmed to be patched to 1.9 and have already tried reinstalling the DX11 patch. My graphics card is a GTX460 so it is DX11 and I am running Win 7 64 bit.
Any ideas? I really would like to replay this game and see the difference in settings.
