V-Ray GPU Requirements

8GB Min VRAM16GB Recommended24GB ProfessionalNVIDIA CUDA

V-Ray needs at least 8GB of GPU VRAM for basic use and 16GB for recommended performance. 8GB for light scenes — whole scene must fit in VRAM

Short answer: V-Ray is VRAM-intensive and benefits most from 16GB+ GPUs. For professional results, 24GB is recommended.
