RTX global illumonation works fine, but when I turn on RTX options, like shasows and reflections, everything is broken. RTX 4070, Win 10 20H2, before and after 4.03 patch.

Ur drivers or drivers shadres are not working right.

You need to uninstall ur GPU drivers, download DDU and clean ur drivers using DDU at windows Safe mode:
https://www.intel.com/content/www/us/en/support/articles/000091878/graphics.html (this guide is for Intel GPU but you do the same and select ur GPU Nvidia/AMD)
after cleaning install newest GPU drivers:
https://www.amd.com/en/support
https://www.nvidia.com/download/index.aspx

also delete all ur dx12user.settings in ur documents/the Witcher 3/ folder and set again all graphic settings in game.

Thank you for your response, I did exactly as you said, I should have done it anyway, but unfortunately it didn't help. Every other game with RTX runs perfectly, but in this particular case nothing changes, except fps, which was already high, grew a little bit more. =(

That's better than what I'm getting.

Yesterday, RT was working nicely (if slowly) with my RX 6600 XT via Proton/vkd3d with Mesa 23.1.0.

Today, it isn't: it's back to the old GPU hangs which, to avoid, require forcing DX11 (which in turn causes dxvk to be used instead of vkd3d).

Most likely a Mesa bug.

I wrote you about it beacuse some user have smillar issue and this drivers cleaning method helps him: https://www.youtube.com/watch?v=H2bE0_mGKHk
But your problem may be related to some mods. The best thing to do is to uninstall the game, locate your game installation folder and manually delete it to make sure that no files remain there. Then, you can install the game again.
If you use mods then install them one by one and check every time which one causing this issue.

I didn't use any mods, and I already tried to reinstall the game, but though before drivers cleaning...
