Józef Kucia : dxgi: Acquire Vulkan image just before present when we have user images.
Module: wine Branch: master Commit: 086f263a9e8457b9758e50eb26cd758b1f53949b URL: https://source.winehq.org/git/wine.git/?a=commit;h=086f263a9e8457b9758e50eb2... Author: Józef Kucia <jkucia(a)codeweavers.com> Date: Mon May 6 11:46:03 2019 +0200 dxgi: Acquire Vulkan image just before present when we have user images. The current DXGI back buffer index is independent of the current Vulkan image index when we have user images. We can use this fact to delay calling vkAcquireNextImageKHR(). This increases GPU utilization from 84% to 100% in the main menu of Metro Exouds on Nvidia.
