Nvidia Releases DLSS 4.5 With Improved Fidelity

Nvidia this year releases DLSS 4.5 with a 2nd-generation Transformer upscaler, claiming better temporal stability, improved resolution, and sharper details; the Nvidia app now supports DLSS 4.5 in more than 400 titles. Notebookcheck tested four AAA games at 4K and found measurable visual fidelity gains but frame-rate penalties varying from about 5% (Black Myth) to 44.5% (Doom), with Preset M favored for higher-quality upscaling.
Key Points
- 1Introduces second-generation Transformer in DLSS 4.5 offering improved temporal stability and sharper upscaling.
- 2Demonstrates tangible fidelity gains in long-distance details and scene stability across tested AAA games.
- 3Requires notable performance trade-offs—frame-rate drops ranged about 5% to 44.5% depending on game and preset.
Scoring Rationale
Solid experimental evaluation and practical details drive the score, limited by incremental novelty and platform-specific performance costs.
