Warning Num Samples Per Thread: Reduced To 32768 Rendering Might Be Slower __link__

Scenes with millions of polygons (high-poly trees, detailed furniture) consume significant memory.

Check Your Light SamplesIf you have dozens of lights in your scene and each has a high "Samples" value (e.g., 4 or 8), the total sample count per thread will skyrocket. Set your lights back to 1 or 2. Scenes with millions of polygons (high-poly trees, detailed

The warning notes that rendering "might be slower." This sounds counterintuitive—shouldn't fewer samples be faster? In this context, "slower" refers to efficiency The warning notes that rendering "might be slower

If this total exceeds available memory on the target device (GPU VRAM), the driver or the rendering engine will either: The "num samples per thread" parameter defines that

In modern GPU rendering, the work of calculating light paths (samples) is divided among many parallel execution threads. Each thread is responsible for a certain number of samples before the results are combined into the final image. The "num samples per thread" parameter defines that batch size.
