OctaneRender GPU FAQ
OctaneRender requires 8GB minimum VRAM and 16GB for recommended performance. Professional workflows benefit from 24GB or more.
The RTX 4070 (12GB VRAM) meets the minimum requirement for OctaneRender but falls short of the 16GB recommended target for professional use.
For OctaneRender at professional settings, we recommend an RTX 4070 Ti Super (16GB) or RTX 4090 (24GB). These have sufficient VRAM and fast CUDA cores for gpu rendering workloads.
Yes, OctaneRender supports NVIDIA CUDA for GPU acceleration. NVIDIA GPUs will deliver the best performance.
