Quote:NVIDIA explains DLSS 4.5 model presets, and shows how to confirm what is running
NVIDIA has published a short DLSS 4.5 Super Resolution FAQ after users ran into confusion with the NVIDIA App’s DLSS Override controls.

The company says DLSS 4.5 Super Resolution moves to a second-generation transformer model. NVIDIA links the image quality gains to more training and algorithm changes, plus a large jump in raw compute demand. RTX 40 and RTX 50 can offset part of that cost with FP8 acceleration, while RTX 20 and RTX 30 do not support FP8 and can take a larger performance hit. NVIDIA says RTX 20 and RTX 30 owners may prefer staying on the older Model K preset for higher FPS.
NVIDIA also confirms two new Super Resolution presets. Model M is tuned for DLSS Performance mode, and Model L is tuned for 4K DLSS Ultra Performance mode. Both can still be selected in other DLSS modes, including DLAA, but NVIDIA frames Performance and Ultra Performance as the intended targets. NVIDIA also says Ray Reconstruction is not moving to the same second-generation transformer architecture in this update, so the gains discussed here are tied to Super Resolution.
Here’s where users have been getting confused by the NVIDIA App UI. NVIDIA’s own app post says that picking “Latest” under DLSS Override, Model Presets will apply the newest model, and it notes that “Latest” for Super Resolution currently maps to preset M.
NVIDIA also added a simple way to verify what is active. Turn on the NVIDIA app overlay statistics view via Alt+Z, then Statistics, then Statistics View, then DLSS to see the model in use.
