Just tested - the bug is indeed gone for me. Cyber Engine Tweaks is broken again though, but there is a newer release for it that works with that hotfix.

I picked up a new 6600 XT and wanted to share the in-game benchmark results on Linux! :smile: This is a really cool experience now.

Using Steam's Proton 7.0-1 with gamemode in the launch parameters.

Nice! I haven't tested this benchmark mode yet.

My result (Sapphire Pulse RX 6800 XT, Wine-staging 7.3, Mesa main, vkd3d-proton master):



My settings are max except screen space reflection quality is set on Ultra, not on Psycho (the latter really degrades performance).

Looks like KHR_ray_query landed in radv. I'll test if ray tracing works in the game now shortly.

Nope, the game hangs if trying to enable ray tracing in the settings.

According to various reports, Cyberpunk 2077 on Linux now performs better than when playing it on Windows when using AMD GPUs (with difference on lower end like Steam Deck APU being even more pronounced). Excellent work of open source developers!

Even with nvidia. Bought RTX 3080 with my friend, both the same model and according to in-game benchmarks we are within ~3% of difference. The only problem for my friend with windows 10 is that he has game crashing every 30 min to 1 hour while i have put 30 hours into it now without a single crash.
How the tables have turned i guess.

Bench result:
2560x1440, all maxed, RTX off, DLSS quality (~84 FPS when DLSS is off)

Spoiler, click me

I'd love this to be a continued trend. I'd... god, I'd just love it! :grin:

Ray tracing started working in Cyberpunk 2077 in latest Mesa main and vkd3d-proton without crashing the game! Performance is completely tanked though with ray tracing enabled 😆, but I wouldn't expect much from this generation of RDNA2 anyway.

Also, looks like some graphics might be not fully correct when ray tracing is enabled.

Set up: Sapphire Pulse RX 6800 XT, 2560x1440.

No RT:



RT (all options enabled, lighting setting on ultra):

With pending [PR !15030](https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15030) for radv performance gets better with ray tracing than without it, though it's still not a playable level on those settings.

No ray tracing ~ 86 fps:



Ray tracing ~11 fps:



Notice also that visuals don't look correct (for example reflections don't seem to work at all), so things aren't fully implemented yet I assume.

I'm beginning to suspect that I really don't need RT in my life. I'm pretty sure it's the future, but the difference between these pictures is so small that they're simply not differences that I'm likely to notice at all.

Reminds me when people compared DLSS to FSR 1.0 - you can certainly tell when it goes wrong, and you can sometimes tell when you're putting stills next to each other. But at 60fps while I'm playing a game? Nope.

I don't really care much about it either, but it's not really working in the current pictures as it should. At least not fully.

So it's not yet at the point of such comparison. It's more just for fun of testing it and the game not crashing with ray tracing enabled anymore.

When it will work, I expect ray traced picture to look objectively better.

Yep, I agree. And lets not forget that CP2077 was an early adopter, so I'm not even sure their implementation is indicative of what's to come. Time will tell! I still need 6800XT prices to dip under £750 anyway, so I'll be waiting a while anyway! :grin:

This game is beautiful! It's a great thing Linux users got a more polished version. :)

I dont get raytracing with lutris/gog version of cp2077 (v1.52) activated.
Is a newer version of mesa needed?

You need Mesa main, vkd3d-proton master and setting these environment variables:

export RADV_PERFTEST='rt'
export VKD3D_CONFIG='dxr11'

And even then it's not really "working", but rather not crashing the game already.

Quoting: Guestbut the ending was a bit dissapointing ... I tried both endings of signing the contract to get another body and refusing and getting back to earth. But I don't know how to unlock the ending where you side with Johny Silverhand and allow him to posses your body. All the other endings I think I will have to go wwaaay more back and load saves from a lot earlier, it should take lots of hours right?

All endings are kind of sad, but in the one with Johnny, V's friends don't die at least. But I think Hanako is killed by Yorinobu in case you don't save her from that mansion, so neither ending is really "good".

To get that ending with storming the tower solo (with Johnny), you need some specific choices in the dialogue with Johnny in the old fields. You can search how to activate it using a command console though in case you didn't make those choices before.

Vkd3d-proton master lets you enable the RTX settings, but it is only fully functional with this branch/PR: https://github.com/HansKristian-Work/vkd3d-proton/pull/1094
Unfortunately it is limited to NVIDIA only from my understanding. RADV still misses some features. That said, on NVIDIA is does look really good, albeit it also tanks a lot of fps. Of course the differences are subtle between RTX on and off, but once I knew where to look for (obviously shadows and reflections :)), I really don't want to miss it, it is certainly next generation graphics for me.

That PR still is a draft, so not really finished and I assume it can take a while.

I agree, at this generation of GPUs this is more of a curiosity, not a very useful feature for that framerate reduction.
