Last year, during CES, Nvidia introduced DLSS 4 and fast forward to today, Jan 6, during CES 2026, Nvidia introduced the model’s next iteration, DLSS 4.5.
DLSS 4.5 introduces a 2nd generation transformer model for DLSS Super Resolution.
Sounds fancy! But what it actually does? It delivers better image quality compared to DLSS 4 for all GeForce RTX GPUs in over 400 games and apps.
Not only that, but it also introduces Dynamic Multi Frame Generation and a new 6x Multi Frame Generation mode.
This allows the GPUs with DLSS 4.5 enabled to “generate up to five additional generated frames per traditionally rendered frame, dynamically boosting performance up to the refresh rate of your display, enabling 240+ FPS gaming with path tracing on GeForce RTX 50 Series GPUs.”
Moreover, the best part about this whole “better frame generation” thing is that while it generates more frames, it also improves certain aspects of the game, like enhancing “in-game user interfaces by incorporating additional game engine data, improving visual quality and clarity of static user interface elements.”
Another key highlight of the new DLSS 4.5 is the new Dynamic Multi-Frame Generation.
What is this Dynamic Multi-Frame Generation?
The Dynamic Multi Frame Generation is an intelligent system functioning like an automatic transmission for your GPUs.
“Instead of sticking to a fixed multiplier, it automatically shifts between different frame multipliers to strike the perfect balance between frame rate, image quality and responsiveness.”
To put it in simpler terms, the DMFG only generates frames required to reach your target frame rate or match your monitor’s refresh rate.
For example, if you have a monitor with a 240 Hz refresh rate, by enabling the DMFG, you can match 240 frames. On the other hand, if you want to fix the FPS at 300, with the new model, you can do that.
Here’s how Nvidia explains the whole process:
“By continuously monitoring the gap between your GPU’s performance and your display’s maximum refresh rate, the system adapts in real-time. In graphically intense scenarios, it ‘upshifts’ and increases frame generation to bridge performance dips, ensuring your high-refresh display remains buttery smooth. Conversely, as the workload lightens, it seamlessly shifts the multiplier down to only compute what’s needed.”
So, how to enable the new DLSS 4.5?
Enabling DLSS 4.5 for all games
To enable DLSS 4.5, open the Nvidia App on your system and click on the ‘Drivers’ tab.
Download the version 591.74 update.
Note: The version might be different and a higher one if you are reading this article at a later date.
Once the update installation is complete, head to Graphics ➡️Global Settings.
Now, select the DLSS Override – Model Presets option.
Set it to ‘Latest.’ And that is it. As for the DLSS Frame Generation Mode feature, it will become available in Spring 2026 via an update.
Note
Before Jan 13th, to enable DLSS 4.5, you must opt in to access beta and experimental features in the Early Access section via Settings > About.
That is everything you need to know about Nvidia’s DLSS 4.5.
Wow, five fake frames for every real one. That’ll definitely not affect input lag at all.
Up until 13th January, when it actually releases, this information is incorrect. Up until then it’s a “beta” release. Typical journo’s not having a clue! Following the above will still keep you on the current Preset K (DLSS 4) (DLSS 4.5 is M). You must tick the beta box to get early access. Open NVIDIA app – Go to settings>about and then tick “Opt in to access Beta or experimental features”. Your welcome.
Once we hit 13th January then the above is correct.
Thanks for pointing it out. My bad. Updated the article with the above note. Once again. Thank you!
