GeForce NOW exploit lets you access the full Windows desktop through a simple file swap — Modder runs local AI models on Ultimate tier with 48GB of VRAM and no restrictions

Summary

Swapping the executable of a game with a modified file will fool Steam into thinking it's opening that game when it's really just giving you unrestricted desktop access. This is against GeForce NOW's terms of service, though, so you run the risk of getting banned.
