Unigine on ROG Ally (Ryzen Z1) – GPU not recognized

[marco.schulz]

Hi all,

I’ve been trying to continue development on my Unigine project while on the go using my ASUS ROG Ally (Ryzen Z1 Extreme). However, the engine fails to recognize the GPU during startup, and I’m unable to get the project to run properly, it crashes right after initialization.

Here's the relevant section from the Log:

Is there any chance to run it on the Z1?

Hi Marco,

Are you able to run other DirectX 12 applications successfully? There have been known driver-related issues with ROG Ally devices in the past, which might be contributing to the problem.

You can check this reddit post:

• https://www.reddit.com/r/ROGAlly/comments/18radxj/rog_ally_software_and_directx12_issues/

Maybe also installing latest GPU driver from AMD will fix this behavior? Here is the short guide how to do this:

You can also check current DX version in dxdiag and share dxdiag log with us.

Thanks!

Actually, looks like you have enabled NULL graphics API somehow. This mode is specifically designed to run on environments without GPUs (servers, for example):

12:48:44 GAPI: NULL

Could you please check if you are not passing -video_api null by accident when launching your application? The same can be done via code. You need to change it something like -video_app dx12 in order to run on DirectX12.

You can also try to delete <Project>/data/configs/default.boot config to make sure that you are running engine without any custom modifications.

Thanks!

Hi, thanks for the help!

I followed the steps from the video, and now the GPU is correctly detected in the log — so that part seems to be working. However, unfortunately, it didn’t really change the behavior.

To narrow things down, I created a fresh project using the example world and also made a standalone build of my own project. The build works perfectly on three different machines I’ve tested it on, but on the ROG Ally, it still crashes both when launching the build and when running directly from the editor.

Could you also please send us the engine log files from the ROG device after updating the drivers to the latest version? The log is usually located in the <Project>/bin directory (log_*.txt files).

Additionally, we recommend updating the Visual Studio C++ Redistributable Runtimes, as outdated versions can sometimes cause unexpected issues.

Also you can try to launch engine with differnt API (for example DX11 or Vulkan) to test the behavior:

Also you can try to reduce memory consumption a bit by turning off the Microprofile tool:

Thanks!

Hi,
none of the suggested solutions worked for me, but I did some testing with older versions of Unigine. Version 2.16 runs fine on the ROG Ally, but every version after that crashes consistently.
