Warning Num Samples Per Thread Reduced To 32768 Rendering Might Be Slower |best| -

: The software tried to set a higher number (e.g., 65536, 131072, or even 1 million), but something prevented it. The engine automatically scaled back the number to 32,768 (2^15). This is a safety cap.

To help you troubleshoot this specific error in your own project: (e.g., Blender, Octane, Redshift) Hardware setup (GPU model and VRAM) : The software tried to set a higher number (e

If you’re hitting performance targets, ignore it. If not, reduce multisampling or resolution first – that often resolves the underlying limit that triggered the reduction. or even 1 million)

Sometimes the warning is device-specific. ignore it. If not
