GPU Performance Checkbox Greyed Out and Reverting to CPU Preview in Illustrator

Question

GPU Performance toggle unavailable in Preferences

My goal is to keep Illustrator rendering the canvas with GPU acceleration (OpenGL or Metal, depending on platform) so that zooming and panning complex vector artwork stays responsive. In Preferences > Performance, the GPU Performance option is either greyed out or appears to revert, and the status bar shows CPU Preview instead of GPU Preview.

I understand from the documented behavior that Illustrator can automatically fall back to CPU-based rendering when the installed graphics driver is considered outdated or incompatible, and that this decision depends heavily on the specific driver version on the host OS. What is unclear is how Illustrator makes that compatibility determination at launch, and whether the fallback is supposed to be persistent across sessions or re-evaluated each time the application starts.

There also seems to be an unresolved question about consistency on multi-GPU systems (for example, a laptop with both integrated and discrete graphics): which adapter Illustrator binds to, and whether the OS-level GPU assignment influences the availability of the checkbox.

Assuming a recent Illustrator version on a supported OS:

What specific driver or hardware criteria cause Illustrator to disable GPU Performance and force CPU Preview?
Is the automatic fallback to CPU mode re-evaluated on every launch, or is it cached until preferences are reset?
On dual-GPU systems, how does Illustrator select which adapter to use for GPU Preview?

Likely causeIllustrator disables the GPU Performance option when it detects that the graphics driver does not meet the minimum OpenGL/Metal feature set (OpenGL 4.0+ or Metal 2.0) or when the GPU model appears on Adobe’s internal blacklist due to known stability bugs. Insufficient VRAM or a driver that reports an older feature set will also trigger the fallback.Confirmed behaviorThe compatibility test runs every time Illustrator starts; the disabled state is not cached across sessions unless you manually reset preferences.On systems with multiple GPUs, Illustrator queries the OS for the adapter driving the primary display and attempts to initialise GPU preview on that adapter. If the primary adapter fails the test, Illustrator may fall back to the secondary discrete GPU only when it is designated as the high‑performance processor in the OS graphics settings.Steps to restore GPU PreviewIdentify your GPU model and driver version (e.g., via dxdiag on Windows or System Report on macOS).Download and install the latest driver directly from the vendor (NVIDIA, AMD, or Intel).After installing, relaunch Illustrator and open Preferences > Performance. The GPU Performance checkbox should now be enabled and the status bar should show “GPU Preview”.If the checkbox remains greyed out, check Adobe’s known‑issues list for your driver version; a blacklisted driver will keep the option disabled until a newer, non‑blacklisted release is available.On a dual‑GPU laptop, open the vendor’s graphics control panel and set the high‑performance GPU for Illustrator.exe (or for the primary display). Then relaunch Illustrator and verify GPU usage in Task Manager (Windows) or Activity Monitor (macOS) while panning/zooming.If you suspect a corrupted preference file, hold Shift+Ctrl+Alt (Windows) or Shift+Option+Command+Control (macOS) while launching Illustrator to reset preferences, then repeat the driver check.If you can share the exact GPU model and driver version you are currently using, I can confirm whether that combination appears on Adobe’s blacklist and advise whether a driver update will resolve the issue.
