📄 Description

fsr_pass only use eR16G16B16A16Sfloat if HDR is enabled otherwise fall back to eR8G8B8A8Unorm
on macOS set thread priority to QOS_CLASS_USER_INTERACTIVE
drift-free absolute timer pacing using monotonic clock and platform specific timing code for macOS and linux (only tested on macOS)
improve sync by switching to vk::PipelineBarrier2
optimize swapchain image acquisition to minimize blocking
