It is shocking how well Arc Raiders handles ray tracing on Linux. I have a locked 60fps at 1440p on my 3070Ti, and tons of GPU headroom to spare.

These Embark people... they scare me.

I think the issue is more about how other games handle ray tracing. For games that just treat ray tracing as an "ultra quality" setting, there's no point of making a low quality ray tracing option, because then you'd just turn it off when non-RT options look just as good.

But Arc Raiders (and their previous game, The Finals) does use RTGI for good effects. And that low quality RT setting is still going to be better than no RT because of its realtime nature. https://youtu.be/MxkRJ_7sg8Y shows that off to good effect.

You can see this kinda performance on Indiana Jones and Doom Dark Ages, which have switched to workflows that require RT. Low quality RT in these games is performant enough to run on Linux AMD drivers which run RT in software on cards that do not have hardware for it: https://youtu.be/44XaGU01J84
