Ring of Elysium and Moonlight Blade, two free-to-play PC games developed by Tencent's Aurora Studios, will support ray tracing thanks to a partnership with NVIDIA. To be precise, Ring of Elysium already added them, while Moonlight Blade will do so with an update due on October 22nd.

Both games are based on the internally made QuickSilverX game engine and will be bolstered by ray-traced global illumination and ambient occlusion. Below you'll find more details on each addition as they were relayed by the developers through a blog post published yesterday on NVIDIA's website. As a reminder, Ring of Elysium can be downloaded directly from Steam, but Moonlight Blade actually hasn't made it yet to Western countries, though you could try to access it via unofficial means.
