Warning Num Samples Per Thread Reduced To 32768 Rendering Might Be Slower [portable] ★

: The scene (geometry, textures, and light cache) is larger than your GPU's total video memory. High Resolution

: Reducing these samples forces the GPU to communicate more frequently with the system RAM through the PCIe bus—a much slower process than using internal VRAM. This can lead to render times that are 10–20 times longer than normal. The "Magic" Number : 32,768 ( 2 to the 15th power : The scene (geometry, textures, and light cache)

: Having too many render elements (passes) during high-resolution renders increases memory utilization. : The scene (geometry
