Nvidia’s frame rate boosting DLSS tech is now a simple download for any game developer

The Nvidia Deep Learning Super Sampling (DLSS) SDK has now been made freely available for anyone to download from its site. Where once you had to apply to use Nvidia’s funky machine learning game enhancer, now it’s just a simple download.

That means, theoretically, it should be easier than ever for game developers to start implementing DLSS into their games. We’ve seen how good it looks in Red Dead Redemption 2, among plenty of others now. Now there’s no excuse not to squeeze in some performance boosting AI goodness into your next title. 

There are three options for aspiring DLSS devs: either grab the full DLSS SDK 2.2.1 download from Nvidia itself, snag the Unreal Engine 5 and 4.26 plugins from the marketplace, or use it natively in the Unity 2021.2 beta.

DLSS is probably the most important feature Nvidia has produced in recent times. It uses advanced machine learning to understand what a game should look like in high fidelity, and then uses your GPU’s AI chops to reconstruct a lower resolution input into a great-looking experience with higher frame rates than at a native res.

It’s worth noting that while DLSS was initially tied into Nvidia’s push for real-time ray tracing in games, as the feature which made the punitive performance hit palatable, we’re increasingly seeing it used completely independently in games just to increase frame rates on its own.

AMD has its own spatial upscaling and sharpening tool, called FidelityFX Super Resolution, which offers a modicum of the benefits of DLSS, but on a platform agnostic basis. Nvidia’s feature is just for Nvidia cards, because of capitalism, and because it does now use those silicon-based Tensor cores in its GPUs.

Nvidia has also this week shown RTX features, including DLSS and ray tracing, running on an Arm CPU system with a GeForce GPUs. There’s got to be an Arm-based GeForce gaming laptop coming soon, right? 

Anyway, Nvidia’s potential feature install base is only growing, with Proton support for DLSS (for Linux gamers running Windows games), and now native Linux support on x86 too.

Nvidia is also updating DLSS itself for both devs and players alike. There will now be a sharpening slider optionally available for developers to drop into their games, which will allow the end user to make images softer or sharper depending on their preference. DLSS is also getting a new Auto mode, which will pick an optimal DLSS setting based on the preferred resolution. That means for 1440p and under you get set to ‘Quality’, at 4K you’re set at ‘Performance’, and at 8K you’re given ‘Ultra Performance.’
