Developer Mods Nvidia DLSS 5 to Run on a Second GPU for 127% FPS Boost

Developer Marcelo Guibout released a ReShade add-on named MGPU Bridge that intercepts finished frames and offloads Nvidia's DLSS 5 neural rendering to a secondary GPU. The dual-GPU configuration yields performance boosts of up to 127% and allows the primary rendering card to run 21 degrees cooler. Moving the neural post-processing to a secondary device allows the system to keep 86% of the available performance gain, rather than losing the majority to native overhead on a single card. The technique requires a secondary display and introduces a doubling of display latency, meaning traditional competitive gaming isn't what the tool is built for. "Neural post-processing saturates whatever device it runs on, and it always runs at output resolution." — Marcelo Guibout
