DLSS 4.5 has arrived! Nvidia recently unveiled an upgrade to its performance-enhancing software at CES 2026 in Las Vegas, introducing a new level of Multi Frame Generation (MFG) that enhances frame generation from the current 4x mode to 6x.
For those unfamiliar with frame generation, it means that only one in six frames is actually rendered by your graphics card, while the other five are generated by an AI model running on your Nvidia GPU. This transition from 4x to 6x could theoretically provide a 50% increase in average framerate.
However, in practice, the performance boost can vary significantly based on several factors, including your system's specifications, monitor resolution, DLSS mode, and game settings. While improvements are noticeable, they may not always align with Nvidia's ideal performance metrics.
Real or Fake?
The topic of frame generation has sparked considerable debate among PC gamers. Some view it as a valuable performance tool, while others criticize it as 'fake frames' and a shortcut for developers to avoid proper optimization.
These concerns are valid, especially since frame generation debuted with DLSS 3. Although I have reservations about AI usage, I initially found frame generation underwhelming, particularly since it is limited to newer RTX GPUs, leaving older hardware at a disadvantage. Additionally, the current surge in PC component prices due to AI demand complicates accessibility.
Yet, with three major DLSS updates, it seems we may need to reconsider frame generation's reputation. The introduction of the 6x MFG mode in DLSS 4.5 prompted me to reevaluate my stance on 2x mode.
Real-World Performance
Using the RTX 5060 at 1440p with DLSS set to Balanced and frame generation off, I averaged about 40 frames per second in Alan Wake II at Medium settings. Activating 2x frame generation boosted this to 55fps with minimal visual degradation.
While 4x mode pushed my framerate into triple digits, it negatively affected visual quality, introducing ghosting and input latency. In Avowed, 2x frame generation provided a 25fps increase without noticeable visual issues, but 4x mode resulted in a blurry experience.
Switching to the RTX 5070 yielded even more significant improvements. Frame generation relies on the base framerate, so a more powerful GPU enhances its effectiveness. For instance, 2x frame generation increased my average from 66fps to 90fps in Alan Wake II, maintaining excellent visual quality.
The Future of Frames
