PayPalAlong with announcing a Native Linux app for GeForce NOW, NVIDIA also revealed the new DLSS 4.5 with Dynamic Multi Frame Generation.
This was announced at CES 2026 with NVIDIA noting DLSS 4.5 brings a "2nd generation transformer model for DLSS Super Resolution" along with Dynamic Multi Frame Generation and a new 6X Multi Frame Generation mode. NVIDIA say when combined this can "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".

What about getting it on Linux? Well, that's where things get interesting. NVIDIA are doing more and more via their Windows-only app, which can make it a nuisance for Linux. A lot of it depends on if Valve's Proton has the necessary bits hooked up for it, and for NVIDIA to ensure their Linux drivers are updated to run with it. Thankfully, NVIDIA say DLSS 4.5 is backwards compatible with existing DLSS integrations in games.
One tool you can try is the open source community-made DLSS Updater, which as of a few days ago version 3.3.0 added Linux support with the developer noting "Going forward, Linux will be officially supported as a platform to use". This should hopefully make it really easy for you to upgrade games. Pretty sweet app, will be keeping an eye on it for updates in future.

Quoting: GoEsrCool, but are we ever getting the DLSS override features? 😡 DLSS Updater (like DLSS Swapper) only lets you change the version, not the in-game modes.We already have dlss override on linux. Take a look at the dxvk nvapi wiki on github. Also some distros like pikaos and cachyos have environment variables that let you update dlss version and change presets. I, myself manually replace game's streamline dlls with the latest streamline sdk version from nvidia github and use environment variables exposed by dxvk nvapi to update dlss preset to the latest and enable multi frame generation.
Quoting: RouhollahWe already have dlss override on linux. Take a look at the dxvk nvapi wiki on github.Those still seem to just be the original DLSS flags, not the newer ones added in DLSS Override like switching between CNN and transformer models. I'm not seeing anything to change that.
