Vulkan - BETA Drivers Break RetroArch/ParaLLel-RDP

[retroNUC]

Last few sets of BETA drivers (tested on 30.0.100.9667 and 27.20.100.9616) break functionality of this Vulkan-based emulator software. Latest retail driver (27.20.100.9466) works fine, suggesting a recent breaking change with the way that Vulkan uses vkGetImageMemoryRequirements/vkGetBufferMemoryRequirements from a quick glance at the code.

There has been no major change to the software, and this issue has also been raised with the developer - "Failed to find memory type/allocate RDRAM" on beta Intel GPU drivers · Issue #26 · Themaister/parallel-rdp (github.com)  

Repro Steps:

1. Install RetroArch (https://www.retroarch.com/)
2. Install ParaLLelN64 emulation core (Online Updater > Core Downloader> "Nintendo - N64 - ParaLLeL")
3. Load any demo application (https://github.com/jsdf/n64-sdk-demo)
4. Using menu (F1), set GFX/RSP plugins to "parallel"
5. Reload demo application, Vulkan renderer fails

Hello @retroNUC

Thank you for posting on the Intel® communities.

Regarding this request and after checking this further, we would like to mention that we are unable to debug/test all the third-party software available out there so in this particular case, supporting this type of issue is out of our scope of support.

We understand that you have already reported this to the software developer. So our recommendation is to continue working with the application developer and verify with them if there is any patch or update available for this type of processor/system (Intel® NUC) especially if other applications work fine. in that case, the best thing to do is to work directly with the app developer.

You may also refer to community forums related to these applications for additional recommendations. Thank you for your understanding.

Best regards,

No worries, thanks for the response. It just seemed that if the same version of a piece of software works on your retail driver but fails on your beta drivers, then it seems like it would be something broke on your end, which is why I thought I would flag it to you.

The developer of this software also appears to be a Vulkan/Khronos contributor, so if he's able to debug further about a specific part of the API that appears to be broken, then I'll try and get him to reach our and post any findings here.
