Experimental Vulkan and X11 Lakka 2.2 builds for x86_64

Posted on 2019-01-16 by mlnlbrt

So far nvidia PC GPUs were supported by Lakka through nouveau open-source drivers.

Unfortunately, these drivers are nowhere as complete as Intel or AMD ones, so while having some advantages (DRM/KMS support, no X Server) this approach has major drawbacks, for example:

Because of the above, PCs with nvidia GPUs were not a good target for Lakka. To overcome the limitations and unleash full potential of these GPUs, the following new experimental builds of Lakka for x86_64 are now available from here:

Generic_VK_nvidia

Vulkan-only build which uses VK_KHR_display extension, implemented in the vendor proprietary driver. This is similar to DRM/KMS, a direct-to-display approach, where input lag should be minimal. As for now, this is the only Lakka variant with Vulkan backends for Beetle-PSX, Dolphin, Parallel-N64 or PPSSPP cores enabled, so you can enjoy features like recently added SSAA option in Beetle-PSX and low-level N64 emulation.

Due to lack of OpenGL this build does not include GL-only cores. It should work with all Vulkan-capable nvidia GPUs supported by 390.42 driver.

Generic_X11_nvidia

Basically, this is a Generic x86_64 Lakka build with proprietary X11 drivers and X Server, so it offers better GPU support at cost of possibly higher input lag. No Vulkan yet.

This build should work with all GPU supported by 390.42 driver and legacy 340.106 driver.
