The TL;DR: The game won’t launch on current steamOS, but preview build 3.7.6 fixes the launch issue.
Unfortunately the game is unable to maintain decent frame rates even with severe reductions in graphical settings.
The drastic decrease in performance compared to Doom 2016/Doom Eternal is due to the game using mandatory ray tracing for lighting.
It’s possible that we’ll see some patches or mods that improve performance, but at launch it will not be a good deck experience.
Not sure what your rant’s about. Ray tracing is a very significant graphical improvement, it has existed in consumer GPUs for years, the game runs great even on earlier cards. That’s it.
Whether you like ray tracing or not is irrelevant to me, and if AMD convinced customers to buy GPUs with mediocre ray tracing performance for three generations in a row, that’s not my problem either.
Yes, but you deepthroating the technology is now relevant to me, because now it’s limiting my options on what hardware I can use to play the game, unnecessarily.
Can I run Doom 2016 on my mechanical pencil? Of course not, Doom 2016 needs hardware capable of fast rasterization, texture mapping, a lot of floating point arithmetic, and so on, a mechanical pencil can’t do that. Fair enough.
Can I run Doom the Dark Ages on a card that lacks ray tracing hardware? Of course not. Fair enough.
I wasn’t the one developing the game, and I also wasn’t the one forcing you to buy a lesser GPU, so again, not really my issue now is it.
People like you defending this nonsense is exactly the issue, but you’ll never realize it.
Cool beans. I really like ray tracing compared to rasterized GI or reflections, so I’m going to happily enjoy the game, thanks.
