RetroArch Vulkan Problem
« on: August 21, 2017, 02:30:43 am »
First off, a big thanks to Calamity for developing CRT Emudriver and providing such amazing support.

After getting my CRT Emudriver 2.0/GroovyMAME Arcade PC working I thought I'd see if I could get that wonderful CRT goodness working with RetroArch. Sure enough after some configuration from this thread: it's running beautifully.

The problem I'm having though is with the Vulkan renderer. I'm hoping to use it specifically for PS1 games and the Beetle PSX HW core's PGXP features. The problem is unless I'm on the latest drivers RetroArch won't start. That's a problem since the CRT Emudriver is based on an older driver version.

I've installed the Vulkan runtime separately as suggested in this thread: According to a view tools I've found Vulkan is indeed installed and can run properly.

I'm unsure if it's the driver itself or a combination of the current card I'm using and the old drivers. Unfortunately I don't have a newer Radeon card on hand to test the idea.

The card I'm using is a Radeon HD 7700 which is the oldest card with Vulkan support. Would updating to a newer card possibly get this setup working or would it be all in the drivers?

I can't help you with this right now. In a few months hopefully I'll have time for an updated release of the Emudriver. In the meantime you can try using latest official driver and Pakoman's method for GM without CRT Emudriver (search the forum). You'll probably mess the GM side of your setup, so unless PSX is so so important to you right now I'd wait for the new release.
Important note: posts reporting GM issues without a log will be IGNORED.
Steps to create a log:
 - From command line, run: groovymame.exe -v romname >romname.txt
 - Attach resulting romname.txt file to your post, instead or pasting it.

Good thing I found this thread. I was excited to try the ParaLLEl n64 core with RetroArch in 15khz 240p on my SD CRT with EmuDriver and was about to follow that same thread you found about installing the Vulcan drivers separately. Glad I didn't now. We'll just have to wait for the next version of CRT EmuDriver.

Has this been addressed? I just picked up a R7 250 and it supposedly has Vulkan support in Crimson drivers 16.3 onward. Unfortunately the CRTEmudriver is based on 16.2.1 which makes Vulkan unusable on my GPU. If there is an updated driver please let me know because I've don't some searching on this site and the official site and have yet to see an update to the driver itself.
