Photoshop GPU acceleration fails in headless production without compatible graphics processor

Photoshop's Preferences > Performance setting 'Use Graphics Processor' controls GPU acceleration for rendering layer styles, filters, and real-time previews. On local workstations with compatible hardware, enabling this setting improves interactive performance and is the default configuration.

In production or CI environments that are headless or lack a dedicated GPU, the same preference causes the application to abort startup with a GPU compatibility error, forcing a fallback to CPU-only mode for scripted tasks. Adobe does not publish a documented fallback mechanism or automatic detection method for headless deployments, leaving operators to choose between performance degradation from disabled GPU acceleration or startup failure when the feature remains enabled. This configuration gap affects automated pipelines where Photoshop must run without user interaction or specialized graphics hardware.

• Can the 'Use Graphics Processor' preference be programmatically overridden or detected in the absence of a compatible GPU?
• What behavior does Photoshop exhibit when the GPU preference is enabled during unattended startup on a system reporting no supported graphics hardware?
• Are there undocumented environment variables or configuration files that influence GPU acceleration fallback in production environments?
