Lumen

Is there a setting to enable/disable Lumen in the graphics menu?

no sadly. The game doesn't have any baked in lighting to replace it with so even if you turn it off by config file the game will be dark as hell.

I don't understand why they force Lumen but seemingly don't use hardware-accelerated Lumen.

I would think that would give a noticeable performance boost if they left the quality the same.

I wish I could turn of Lumen and the other UE5 things that make my 2080 Ti unable to play them at 1440p

As said above, they don't have a baked GI to fall back on, so you'd only get direct lighting which would look awful.

If it is only using SW Lumin (which I would concur is likely, based on benchmarks) it would be because the game was designed to be ran first and foremost on consoles, which have really crappy first gen AMD RT performance.

IIRC, it wasn't until RDNA3 that AMD even dedicated die space to dedicated RT cores. Even RDNA 3 just has RT being done on regular compute cores split off of from the main stack, and when they got overwhelmed (which happens fast in heavy RT games) the workload would bleed into the main CUs and utterly tank performance....they're still a few generations behind NV at best, really.

Thus, while HW RT may be faster on some (most?) NV cards due to their dedicated RT cores, on AMD systems (which includes something like 80m consoles) you'd likely see CyberPunk style performance deltas on benchmarks where you have basically unplayable performance. Considering the game cannot be played without RTGI, my guess is they decided to go with the option that ensured the most amount of people would be able to /play/ the game, even if that does ♥♥♥♥ over NV users as their RT cores went off for cigarettes and beer while their main cores are getting the snot beat out of them.

Why not implement both as options? Dunno, but I'm hoping they patch it in at some point.
