I've compared a windows build of [vkoverhead](https://github.com/zmike/vkoverhead) test case 92, which uses descriptor buffers, on latest wine from git. I'm getting a score of around 48000 operations per second without this patch, and around 84000 with this patch using direct calls, so still almost a 2x difference. FWIW, a linux build without using wine gets around 320000 in the same test, all using the RADV vulkan driver.  
I haven't tested it with actual games yet, but I expect it to still have a noticeable effect on CPU-bound games with vkd3d-proton.
