Due to a recent migration I performed of the Bitbucket repository into GitHub, there is now a new release of Slip & Frag, the Quake sourceport for modern machines & VR devices.
The new version has a fix for a few unexpected bugs related to model, sound and particle handling in the core engine. Also, most visual artifacts present in large maps / mods were finally removed, due to optimizations applied to surface lightmap handling when rendering the VR versions. And, finally, there is now a new PCXR version (that is, a PCVR version that runs in Windows, that uses the OpenXR runtime from Meta for their devices) which should run as well as the standalone version.
