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...
Armed with the knowledge above, I've come up with a solution to the issue for those willing to sacrifice RTX 40 features to get working HDR (a fine trade off imo, but it's situational).
- Browse to the Need for Speed Unbound directory (eg C:\Program Files\EA Games\Need for Speed Unbound)
- Rename nvngx_dlssg.dll to anything else (eg nvngx_dlssg.dllX)
...this will have the effect of disabling the RTX 40 features, and also fix HDR. Of course renaming the file back will return the game to its original state.
Enjoy a much prettier looking game 40 Series fam 🙂
EDIT: just to preempt the question, the DLSS upscaling and Reflex features should still work fine with this change,
Oh my god great thinking!
I will use this workaround until they fix HDR with FG, thank you!! 🙂
Yep this fixed it for me! Great job!!!
Oh great, have you tried other nvngx_dlssg.dll versions ?
I've read that the one from The Witcher 3 is not that good and needs to be replaced by another one (maybe the Portal RTX one I don't remember).
I'll try when I get home.
Ok so I tried two other DLSSg files and still no HDR, renaming it is the only ways to get HDR working.
The game has version 1.0.2, I tried 1.0.3 and 1.0.4 (found in today's Portal RTX update).
That's fine, no need for frame generation, the 4090 can handle 4K120 with ease anyway 🙂
