Hello, thank you for providing the detailed system environment and issue description.
Regarding the issue you mentioned, where UniFab 4.1.4.0 crashes without any error message after running for a while when using the Equinox model in AI Upscaler for 8K upscaling, we understand that this affects your normal use.
As for the “UniFab 4.1.x Ryzen-to-NVIDIA hand-off bug” mentioned by Google Gemini, we cannot directly confirm whether this description is accurate at this stage, nor can we determine that the issue is definitely a known bug based only on a third-party AI analysis.
Since this issue involves 8K upscaling, the Equinox model, the hardware combination of AMD Ryzen 9 9950X3D and RTX 5090, as well as the specific processing status when the software crashes, we need to further investigate it based on the logs and runtime environment.
To help our technical team analyze the issue, please provide the following information:
The format, resolution, duration, and encoding information of the source video used in the crashed task
The full parameter settings selected in AI Upscaler, including the model, output resolution, frame rate, etc.
Your Windows system version and NVIDIA graphics driver version
The UniFab log files before and after the crash
If possible, the related error records from Windows Event Viewer when the crash occurred
After receiving this information, we will further check whether the issue is related to the current version, hardware compatibility, or abnormal GPU invocation, and provide corresponding suggestions based on the investigation results.
Before the issue is confirmed, you may also try updating or rolling back the NVIDIA driver, closing other programs that may be using the GPU, and testing whether the crash still occurs with a lower resolution or a shorter video clip. This may help narrow down the scope of the issue.
