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

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 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!

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.
