I just got the game surprisingly, i won't be playing it throught this busy weekend so more on monday but i just installed 11.9 catalysts, got all those rageconfigs together into one and applied that, the game crashes on startup , but i found a workaround, pressing alt-tab at the start makes the game work and then just tab in when i hear intro sound. I got command line params too.
So inside the game there's constant flickering of corrupted textures all over the screen ... this is a driver problem so that's understandable. Texture loading isn't the best yet but it's quite playable, actually it's very good game besides these things, i only did the first quest.
One particular bug that i will stress out is BEING STUCK , i was stuck TWICE and i needed to kill my self but i forgot to see if there is a /kill cmd in the console , well but there is something "mising" a command called "show_pos" or "dump_pos" to display or save into file the PLAYER COORDINATE POSITION so i will be able to SUBMIT that for bug fixing. I still remember when these 2 places are, please notify carmack to add player position command (i remember it from call of duty but maybe IW added that)
Some games were able to unstuck but here it was completely impossible, acting wacky pressing all buttons crouch prone did not work, but somehow throwing a grenade below you somehow makes you unstuck when your damaged, but it didn't always work.
Some are reporting way more problems and those may have much more chance to arise from crappy PC maintenance and general PC health. There is really a lot less of those valid guys "coincidentials" that do have great PC management but still have a big problem like BSOD.
There is hard to fix stability for many configurations , still many are valid such as mass reports of crashes when starting to CTDs ... in between the mess some of them have something due to improper driver installs, be sure to use DriverSweeper to clean out the mess before reinstalling if your unsure about it.
