I've Put Nvidia's New Dlss 4.5 To The Test: 's How To Enable It

While we weren't expecting any major PC gaming announcements from Nvidia at this year's CES event, it was still somewhat disappointing that the main things we got were an update to DLSS and a new version of G-Sync Pulsar. But that's okay, because as it so happens, they're both actually pretty good. Well, in the case of the new DLSS 4.5, it's mostly good.

With version 4.5, Nvidia has introduced three new elements to its AI-powered suite of rendering technologies: a second generation transformer neural network for DLSS Super Resolution (aka upscaling), dynamic Multi Frame Generation (MFG), and a 6x mode. However, only the first one is available to use right now, as the new frame gen stuff won't make an appearance until spring.

In order to force games to use the new upscaler, you'll need to use the 591.74 GeForce Game Ready drivers, plus the latest beta version of the Nvidia app (though a full release may be released by the time you're reading this). To get that, click on the Settings option in the Nvidia app, then select About, and finally check the option to opt into betas. You'll probably need to restart the app after that so that the program can check for an update.

It's important to note that DLSS 4.5 Super Resolution doesn't automatically work, as things currently stand, and you will need to enable it on a per-game basis. For example, if you want to use DLSS 4.5 instead of DLSS 4 in Black Myth: Wukong, head to the Graphics menu in the Nvidia app, select the game, and then scroll down to Driver Settings.

You should see an option labelled DLSS Override - Model Presets. By default, this will say 'Use the 3D application setting', but when you click on that, you'll be shown the following window.

If you don't want to mess about with DLSS neural network models/presets, just click on Latest, followed by the Apply button. The next time you dive into Wukong, it will be using the new transformer model for upscaling. Do note that it won't affect frame generation nor will it change how DLSS Ray Reconstruction works.

The latter is especially important to note because when you enable that in a game, it automatically uses its own version of DLSS Super Resolution, and for the time being, that still uses an older neural network. I'll say more about this later on.

DLSS Override also lets you select a specific model or preset, and Nvidia added two new ones in the new
