AVBD 3D — GPU benchmark

Runs the whole 3D step (collision, colouring, solve) on this machine's GPU for a fixed scene suite, including the paper's large scenes, and compares with the paper's RTX 4090 times. Close other GPU-heavy tabs and keep this tab visible while it runs (hidden tabs are throttled). Small and paper-scale take about a minute; the 510k scene needs about 1.2 GB of GPU memory.
