Modding Pac-Man with DLSS 5
A tech enthusiast showcases the MS-DOS version of Pac-Man running with 4x Multipass across four different rendering modes, producing glitchy and unusual visual effects.
This experiment highlights the trend of applying advanced upscaling technology to games that were never designed for modern 3D rendering or AI enhancement.
Injection via Emulator and ReShade
The experiment was achieved by running Pac-Man through the MAME arcade emulator, using ReShade to inject DLSS 5 into the graphics pipeline, and RenoDX to tweak the parameters externally.
Using 4x Multipass is necessary because older games do not benefit from a single pass. Since Pac-Man lacks 3D geometry and human-like features, the upscaler attempts to interpret flat pixels, occasionally generating unexpected facial structures like cheekbones or sunken eyes.
Rendering Modes and Visual Glitches
The experiment tests four rendering modes: Natural, Default, Cinematic, and Denoise. Each mode alters the appearance of the maze and characters drastically, ranging from readable mazes to total removal of game elements.
Certain configurations remove the eyes entirely from the green ghost, creating a startling visual reminiscent of classic internet horror stories.
State of the Upscaler
The leaked DLSS 5 build remains undertrained and lacks temporal context compared to mature models, serving as an early glimpse before a formal release.
