hi,

the game in question is gran turismo 5 within RSPC3 using vulkan

the error is inconsistent it can trigger 30 seconds in other times ive ran 3 hours without a fault

i only recently reinstalled the game in question and after getting everything compiled i started getting VK_ERROR_FRAGMENTATION when using vulkan as the render as aposed to OGL

SSU is attached below,

thanks.

ok just hit a fault in gran turismo 6 too looks to be the same fault will attach logs below but this is the end line 

SIG: Thread terminated due to fatal error: Assertion Failed! Vulkan API call failed with unrecoverable error: Descriptor pool creation failed (VK_ERROR_FRAGMENTATION)

you will have to excuse the log being 124MB uncompressed but this run has been holding for a quite a while before 

actual vram usage on the gpu at point of error was 11/16GB exact

Hi sam244,

Thank you for providing the information. To properly isolate the issue with your Vulkan-related concern, I would like to request that you follow the steps below, as this may help resolve the issue:

Clean Installation of Intel® Graphics Drivers in Windows*

I highly recommend using the DDU (Display Driver Uninstaller) method to ensure a complete removal of existing drivers before reinstalling the latest version.

Please let me know once this has been completed and share your update.

I will wait for your response.

Hi sam244,

Thank you for providing the additional logs and for confirming that the issue persists even after updating the drivers using DDU.

With this, please allow me some time to review this internally and work on reproducing the issue.

I will keep you updated as soon as I have more information.

Hi sam244,

Thank you for your patience. Upon further checking, RPCS3 is a free, open-source PlayStation 3 emulator and debugger that allows users to run PS3 games on modern PCs, as well as macOS, Linux, and FreeBSD systems.

With that in mind, I would like to clarify a few details are you using the emulator as a user, or are you involved as a developer? This information will help us better understand and address your concern.

end user, i just own gran turismo 5/6 and am still waiting for sony to do a pc native release  though that error seems present on most things ive ran on it while using vulkan as the render

[JohnM_Intel]

Hello sam244,

Thank you for the clarification that you are an end-user.

As RPCS3 is an emulator, we highly advise you to seek assistance directly from the developers, as the issue you are experiencing requires their specific attention.

We understand this may not be the resolution you were expecting; however, this falls outside the scope of our support.

For this reason, I will proceed with closing the case.

Regards,
