Hi all, I used to be able to use RTX HDR with the TETR.IO Windows app until a few months ago, but on the latest version of TETR.IO this compatibility seems to have stopped. The RTX HDR option is always greyed out in the Nvidia overlay when TETR.IO is open. I've tried all sorts of driver settings and using tools like NvTrueHDR, as well as trying to use Windows Auto HDR, but nothing works. On many laptops the screen can hit much higher brightness with HDR enabled so that's the reason I'm keen to be able to use it again. Would be super grateful for any help.

i mean there's no configured HDR content in the first place so we don't have any official support of any third party tools preporting to add it

Makes sense, ty. Do you know if anyone else has had issues getting TETR.IO to play ball with Nvidia drivers since v10?
