Not that simple. It’s not just about what chip they’re using, its the fundamental premise of how it’s built.
Keyshot was meant to deliver fast raytracing which is what gets you photorealism, proper lighting reflections, refractions, shadows, etc.
VR and GPU based tools leverage the OpenGL and DirectX and CUDA optimizations that emerged from gaming to allow people to visualize things instantly.
There are GPU based raytracers out there that take advantage of CUDA and GPU performance: GPU Rendering Solutions for 3D Designers | NVIDIA
The issue is while these ray tracers may be faster, they still aren’t 90FPS a second fast which is what you’d need for VR that doesn’t induce nausea.
