The warning is a common diagnostic message in V-Ray GPU (and occasionally other CUDA-based renderers like Octane). While it sounds alarming, it primarily indicates that your scene is pushing the limits of your GPU's Video RAM (VRAM) . What the Warning Means
Convert high-poly objects into V-Ray Proxies to manage memory more efficiently during the loading phase. Manage Hardware Resources function show(msg) text = msg; open(); The warning
The warning says rendering might be slower, which sounds confusing—usually, fewer samples mean faster renders. However, in this case, "slower" refers to efficiency.

(available in V-Ray 6.1+) to reduce memory footprint without losing visual quality. Reduce Light Cache Subdivs
Here are practical solutions, from simplest to most advanced. Rendering might be slower
Example:
Fix: "Warning: num samples per thread reduced to 32768 rendering might be slower"
