On "shimmering": On placebo effects:There is built in tool to compare performance, configurable with perf_graph and use_dx9 options.Somehow no one used it to make up some solid arguments other than self perception. On d9vk:While for linux it works really well compared to wine d3d & other things, i did not encounter any changes between stock dx9 on windows.Maybe 5700xt dx9 driver is so bad that anything helps, dunno.
