This demo was running 2 CNN networks, face & landmark detection. The tx1 chip was not that powerful nowadays but this demo could still run in real time at 25 fps. Btw, CPU was overclocked.
I have a JP version new 3ds xl (never accessed eShop) and did a region changing to US following https://3ds.guide/region-changing . So is my console totally the same as a real US region console now?
