Poor support indicates that the driver is not able to properly handle Vulkan realtime shaders and it will present as visual stutter. Non-robust solutions will suffer stutter under very high GPU load. -- **PRIME/ Hybrid GPU Support**: Compatibility with systems using multiple GPUs for render offload. Monado and all clients must be run on a single select GPU due to memory tiling requirements. -- For Nvidia proprietary drivers *older* than 565, (please try to update!), the [vulkan-layers](https://gitlab.freedesktop.org/monado/utilities/vulkan-layers) must be installed in order to not crash: [*AUR*](https://aur.archlinux.org/packages/monado-vulkan-layers-git)・[*Fedora*](https://packages.fedoraproject.org/pkgs/monado-vulkan-layers/monado-vulkan-layers/) - **Nvidia Wired VR Workaround**: Wired users should certainly set `XRT_COMPOSITOR_USE_PRESENT_WAIT` to 1 which changes the swapchain to explicit sync behavior and `U_PACING_COMP_TIME_FRACTION_PERCENT` to 90, representing 90% of the time it takes to render a frame can significantly reduce the latency effect with Nvidia GPUs. There are notable frametime issues in the driver still which may result in stutter but this should vastly improve the experience. -- Nvidia GPUs work well for wireless VR through WiVRn. -- AMD GPUs
