EverLive has been released in version v1.4.0 - two days after v1.3.2.
EverLive is an open-source userspace driver for the AVerMedia Live Gamer 4K (GC573) capture card, letting you play and stream PlayStation 5, Xbox or Switch on the Linux desktop.
The update brings 2x frame generation (beta) via lsfg-vk and support for the AVerMedia Live Gamer DUO (GC570D) with simultaneous dual-HDMI capture. It also adds an SDL2 preview with virtual cameras and several bugfixes, including 4K capture without relogin.
Changes in version v1.4.0:
Added

lsfg-vklayer, with 30 to 60 FPS and 60 to 120 FPS modes, an optional low-latency swapchain mode, and automatic Steam library discovery. Optional, falls back to native presentation if components are missing.- AVerMedia Live Gamer DUO (GC570D) support: Blob-free userspace
