  • It needs to be implemented per-game because of quantization. See, tonemapping operators are reversible, meaning you can feed in a tonemapped image into the inverse tonemapper and get an exact duplicate of the non-tonemapped HDR image. Well…you can provided it hasn’t been 8bit quantization. If it has then there are only 255 possible values, because it throws away everything in between as part of the process, meaning that even once you do the inverse tonemap there still only 255 possible values, only now there is a vast gulf of possible brightness between 254 and 255. As an example, maybe 254 is 300 nits, and 255 is 3000nits. Well that’s going to be noticeable, even more noticeable than the banding when just using SDR.

    In order to implement HDR properly it needs to be implemented before quantization.













  • I have one. It’s gorgeous. For emulation, older games, and those that support FSR2, it’s well worth it. New AAA titles struggle at 1200p…but that was already true of 800p so it’s not like it’s much different. Even so you can run something like Cyberpunk 2077 at 1600x900 with FSR2 Performance and get comparable performance to FSR2 Quality @ 1280x800, only it’s 16:9 and looks far better.

    It’s not perfect, but for those with the technical skills to do the swap in the first place it’s a decent upgrade. People also vastly overestimated the BIOS updating issue. I’ve updated SteamOS no less than 4 times (3.5.1 -> 3.5.5) since installing DeckHD and not a single update has overwritten the BIOS. It will happen eventually, I’m sure, but it’s a far cry from the “every update” that people parroted.
