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

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.
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.

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!

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.
