Great post, thank you for posting. I had a 'working' workaround for SDR already, and somehow got it in DV with a normal image once or twice by messing with alot of things. But your info is correct.
Very useful windows shortkey as well that I didn't know yet.
Edit: do you also have spots / sparkles on the screen this way?
Edit2:
- The weird spots on the screen are caused by using resolution scale under 100.
- Ini file is documents/Need for Speed Heat/settings/PROFILEOPTIONS_profile (incase someone was missing this info)
- Works if you want to play in 1440p as well, windows has to be in 4k then.
- Works only for me if FullscreenScreen 1 and FullscreenMode 0, FullscreenMode can be set to 1 unwanted if you switch screens / test workarounds/ alt enter.
- Not sure what H3llf1re does to re-enable the gfx card. After playing the game, things are still not completely normal and it seems to be that Nvidia colour setting dynamic range is changed to full. Changing it back to limited will trigger the black DV screen. Reboot will fix that.
