Released last week was the LuxCoreRender 2.5 open-source physically based renderer. Significant with this v2.5 update is OptiX/RTX acceleration support in addition to its existing CUDA, OpenCL, and CPU render paths. Given that, here are some fresh benchmarks of LuxCoreRender 2.5 across an assortment of NVIDIA graphics cards.

If all goes well Linux 5.12 will be released tomorrow and in turn will kick off the Linux 5.13 merge window (otherwise 5.12-rc8 will be issued and the stable then a week later). In any case once the Linux 5.13 merge window does open there are a lot of prominent changes expected...
