Valery Kryzhanovsky is testing Nvidia’s DLSS 5 technology on classic DOS games like the original 1991 Duke Nukem and the 1972 game Pong. Although DLSS 5 was designed for modern titles, Kryzhanovsky has created a method to apply it to older software using DOSBox, ReShade, and RenoDX. He notes that while the technology adds depth through embossed visual elements, applying it too strongly can result in images resembling an acid trip.

Kryzhanovsky explains that DLSS 5 relies on motion vectors and object selection which are absent in static 2D images or improperly injected 3D games. To mitigate this, he advises choosing the specific rendering stage where the filter is applied, such as after upscaling or at the final output. He found that injecting the filter at the render stage can alter actual face geometry in 3D titles like RBDOOM-3-BFG, whereas force-injected DLSS 5 works best with still images like Heroes of Might and Magic.

Despite these caveats, Kryzhanovsky believes the technology is promising but currently undercooked. He identifies a lack of temporal elements as a key drawback, noting that the system only analyzes the current frame rather than using data from previous frames. His testing covers various genres from 2D platformers to contemporary games like The Witcher 3, providing detailed instructions for others who wish to replicate his experiments.
