Why do you think all of the gameplay footage was of console versions?
Now they blame it on drivers so they don't look bad. This is 100% ID/gamesas's fault. If you think otherwise you're naive.
ID / gamesas = lying scum
Carmack = lying scum
"Open world" yea right
Ok, we don't do threads just to rant here nor accuse folks of being liars.
If they knew, they would have fixed it. It is unfortunate that there is not ever time to test on every pc, ever configuration and every graphics card out there today but no company can.
It is also unfortunate that folks are having problems but it is fortunate that the developers, graphics card makers, publishers and steam folks are doing everything they can to get it fixed for those who are having problems.
I know it's no consultation but there are many who are playing on PC with no issues at all. Now they are working to ensure that is true for as many customers as possible.
If you want to post to document your problems or to help others with their problem, feel free to do so. If you post just to rant however, it helps nobody and spams up the forum making it more difficult for those having problems to find solutions or for them to know where to put their documentation.
