Hi, would anyone be able to provide a fresh Win-64 build of RA with Vulkan and all of the cores? Also, do you need a new set of shaders for Vulkan?
Actually, it seems to not be working. This is one of the reasons I was trying to compile RetroArch with Vulkan support for Windows but I got stuck on some dependencies. (I also compiled with OpenAL support as it interests me, with just OpenAL I managed to compile just fine) Log from today’s nightly build:

Dota 2 works perfectly with Vulkan.
Can you try again? Twinaphex pushed a commit today that should have fixed it.
Also, make sure you’ve initialized and updated the git submodules.

It seems that the compilation failed as there is no executable. On the build bot build log this error showed up:

But this file can be found in …\home[USER]\RetroArch\deps\SPIRV-Cross in the source code.
EDIT: For some reason it worked when I forced it to compile by removing “check_lib VULKAN -lvulkan vkCreateInstance” from “config.libs.sh”. I compiled with vulkan support on Windows and according to the log everything is working fine.
EDIT2: I am testing with a notebook with Optimus support and not even with hard sync enabled (unless I use hard sync and the integrated HD 4000, which is not very good as everyone knows) I get low input lag with my nVidia 650M. With Vulkan I seem to be getting less input lag than with GL and hard sync but taxing the CPU a lot less, nice. (but still not as good as the HD 4000, sadly) What is the V-Sync issue from here: https://github.com/libretro/RetroArch/issues/3005 ? I just tested bsnes-mercury, but it seems to work fine.
[QUOTE=lagonauta;40190]What is the V-Sync issue from here: https://github.com/libretro/RetroArch/issues/3005 ? I just tested bsnes-mercury, but it seems to work fine.[/QUOTE] I tested the latest buildbot build with the Vulkan driver and the swap interval and black screen insertion options don’t work with it. Those two make vsync smooth on non-gsync high refresh rate monitors; maybe them not working are part of the issues?

The stuttering issue was an Nvidia driver issue which they’ve since fixed in their latest Windows driver.
Vsync Swap Interval and Black Frame Insertion are not implemented yet in the Vulkan backend yet as far as I can tell. The bilinear filtering option in Settings>Video does not work either, though that can be enabled through slang-shader presets.
I went and tried the latest nightly to see how Vulkan ran, but it didn’t run at all for me. The executable detected Vulkan support, but when I set the driver to Vulkan, it crashed every time. I went and enabled logging, but it just raised further questions, because the log shows absolutely no indication of why the crash happened. It just sort of…stops?

Do you have a video card that supports Vulkan and the latest driver for it? Vulkan support in hardware is still very new.
I have an R9 285 running with the latest AMD driver (16.5.3). As far as I know, the 285 supports Vulkan just fine, though I haven’t had the opportunity to test with any other apps. I wouldn’t even be trying this if I didn’t think it was possible, and RA correctly says that my system has Vulkan support in system information. So…I have no idea what’s wrong!
I don’t think AMD’s Vulkan driver is mature enough yet. Intel Ivy Bridge is in the same boat in that there are drivers, they just don’t work.
