Great. Also mentioned in changelog: support for Nvidia DLSS. Would be interesting to hear some feedback or to see test/benchmarks.

I wonder when they will add support for Mass Effect Legendary Edition?

and I wonder when will they fix Dirt 5, since it is AMD showcase game and most devs use AMD on Proton.

RT support in general would be nice especially for Amid Evil, that needs DX 12
Excited to try it out!

I'm playing Doom Eternal right now and the DLSS is making some difference to me.
On my RTX2060 at the Nightmare Preset and 3440x1440@75Hz, without DLSS I get around ~60fps, with DLSS on Quality, something around 70FPS and I can get 75FPS with the Balanced Preset.
I still haven't tested without Vsync but for me, the experience is nice so far.
I tried Raytracing as well. It's working good but my card wasn't made for that at least not at this resolution.
Even with the preset on Medium and DLSS on Performance, I can get 35FPS max with RT enabled. But at least the effect is working really well.
I hope they fix the long loading time for DX12 titles....
