For those interested, following are the INI settings I used. There were so many variables I tweaked that I don't fully remember what I did.
Please do not hold me responsible if this crashes your system or breaks up your marriage. I followed Andy's guidelines for half of it. The rest, well, I was just a monkey with a spanner. I wanted to document everything the way Andy did so well, but I had no time or sleep. Just run the original user settings file against a text compare tool and you will see what I've changed (if you are so inclined). Good luck and let me know how it goes.
The only issue I've noticed is that some cutscenes that I remember having strong depth of field do not show it anymore. Have no idea why. Other than that I haven't really noticed any pop-in or streaming issues that accompany an open world game. I've got way too many screenshots that I need to organize, so for now, please bear with me for reposting the ones I posted earlier.
Also, this is still a work in progress. Shadows tend to be over exaggerated if the conditions are too bright. It still looks great, but some areas can get completed drowned in shadows. Will try to fix that. But I want to play the game as well, so we'll see!
My configuration:
Inter 5930k hexacore OC @4.4 Ghz
Titan X 2xSLI OC @+200/+400
16 GB DDR4 3000Mhz Ram
1 TB Samsung Evo SSD
Asus x99-A motherboard
Seasonic 1200W Platinum PSU
Corsair 500R case
Corsair AF120 Fans
H105 Water cooling
Logitech wireless KB
Logitech G930 headset
Windows 8.1
Resolution: 1440p. 4K60 ultra was too much for my rig with hairworks. It was possible without, but I had no headroom for these tweaks. And I don't have a gsync monitor, so 60fps vsync or bust. If CDPR can optimize even by 10%, I should be able to bump it up to 1620p.
FPS w/ ultra w/o tweaks: 90-105
FPS w/ ultra + tweaks: 70-90
Sample screens:
WoW Viveks that looks absolutely stunning. The Foliage looks so much better. Like 10 steps up.
Now please buy me your rig
Thanks for all the effort. It would be cool to have a comparison Video, but I guess that is a lot of work
