New 455 drivers drop and here is what to expect;
In addition to the RTX 3080/3090 support there is also official support for the GeForce MX450. This Linux beta driver also adds NVIDIA VDPAU support for decoding VP9 10-bit and 12-bit bitstreams, the base mosaic support now allows five simultaneous displays rather than three, the removal of SLI modes, support for the NVIDIA NGX updater, and various bug fixes.
There is also a performance optimization in that there is device-local VkMemoryType that is host-coherent and host-visible. This new VkMemoryType should help DXVK titles like DiRT Rally 2.0, DOOM: Eternal, and World of Warcraft.
