Same issue here, with an RTX 4090 and LG OLED. HDR doesn't kick in at all. Works fine in all other games and NFS Heat.
Best I've managed so far is to force a 10bit swap chain with SpecialK - the resulting picture was much too dark though (because the game is not outputting HDR properly). Any attempt to force a 16bit scRGB swapchain results in an immediate crash.
Please fix this EA :-/
EDIT: oh, and I have flashed the updated vBIOS onto my card.
DOUBLE EDIT: Looks like HDR is also broken on PS5 and Xbox https://www.youtube.com/watch?v=n8nyQdo0Ci4
4090 and OLED TV (LG C1 but I don't believe it matters) here as well but I feel like it's not related to the card. It's not that there is odd behaviour or anything, the option just seems to not do anything.
I maxed the brightness in Game Optimizer mode in SDR and it's spectacular either way. Loaded up the XBOX Series S and, even though it has Dolby Vision and it might be slightly brighter in some places (more about the dynamics and diff in bright and dark, but subtle differences), the resolution detracts from the benefit that HDR could provide. And it's smooth, but it's not 100+ FPS smooth. I'll still take PC without HDR over console with HDR, but we shouldn't have to choose for a $90 game. Patch 1.04 didn't seem to fix it.
I did update the VBIOS on the card (which actually seemed to fix the very seldom frame drops I was getting, super buttery smooth now).
The gameplay experience is quite great, imo the best NFS in 10 years or more. Welcome back, Criterion. But please fix HDR on PC!
I can confirm that the most likely reason HDR isn't working is because of the 4090rtx. I was able to have HDR work perfectly on my 3080 computer but it doesn't activate on the 4090.
The only other possible reasons there might be issues is that one is 3080 is using windows 10 and is hooked up to a LG C9 and the 4090 is using windows 11 and is hooked up to a LG CX.
So with that being said most likely nvidia needs to make an update or motherboard bios needs and update. I notice this issue also happens in Callisto Protocol however it isn't happening in other HDR games. For instance Cyberpunk 2077 looks amazing with HDR.
I think you are right about RTX 4000 series.
HDR works perfectly on my RTX 3080 laptop, but it does not work on my RTX 4080 desktop and no workarounds help.
Both tried on two different TV's and result is same with RTX 3080 HDR working and RTX 4080 HDR NOT WORKING.
Either Nvidia or Criterion needs to update something :S
This has spuriously started working for me today. I didn't do anything special to make it work. Weird! It's working reliably too, survives reboots etc.
I didn't notice any game or driver updates come down since the last time I tried this.
Anyone else?
7950x, 64GB, RTX 4090 (latest vBIOS)
EDIT: Ok, it looks like the reason for this is that the driver is broken, as I've lost the ability to turn on DLSS Frame Generation in any game. Very interesting though that HDR starts working in this game if the RTX 40 features aren't available...
