Nvidia has launched the second half of the DLSS 4.5 feature set today, with the release of DLSS Dynamic Multi Frame Generation, more aggressive 5x and 6x frame-gen multipliers, and a new "enhanced frame generation model" now available in beta. The new tech is available for RTX 50 series users only (with one exception, details below), and can be activated in the Nvidia App through DLSS' override presets for games that don't yet natively support the new tech (yet).
Nvidia first announced DLSS 4.5 in its entirety at CES 2026 in January. DLSS 4.5 multi-frame generation uses Nvidia's 2nd-generation DLSS transformer model to achieve 5x and 6x multi-frame generation on RTX 50 series GPUs while improving image quality.
However, somewhat confusingly, Nvidia has also introduced a new "Preset B" frame generation model that improves frame generation image quality in conjunction with the DLSS 4.5 Super Resolution model. This new Preset B model takes into account "additional UI buffers" available to certain game engines to more intelligently render UI elements with fewer artifacts (such as reduced crosshair flickering). The new model can be selected in the Nvidia App frame generation override dropdown menu, dubbed, and is supported on RTX 50 and RTX 40 series GPUs.

Nvidia has also introduced a new dynamic frame generation mode that will change the DLSS multiplier on the fly to match the maximum refresh rate of a monitor. If frame rates exceed the monitor's capabilities, DLSS will automatically reduce the multiplier to keep within the refresh rate limits of the display. These sky-high frame generation multipliers, combined with dynamic frame-gen, are designed to fully saturate the capabilities of 240Hz and 360Hz gaming monitors in graphically challenging titles. (The 5x, 6x, and dynamic frame generation tech are RTX 50 series exclusive, just to be clear.)
However, as we've said in previous articles, multi-frame generation is not a tool that will magically make unplayable frame rates playable even on Nvidia's latest graphics cards. If a game is running at 30 FPS and you turn up DLSS to a 6x multiplier to achieve 180 FPS, the game will still feel like it's running 30 FPS. You still need a high base-frame rate to make frame generation work well. The only technology that could potentially change that is Nvidia's Reflex 2 technology, with VR-inspired spatial reprojection, but the technology has been significantly delayed since its announcement and still does not have an official release date.
DLSS 4.5 will likely be the last DLSS 4 version as Nvidia shifts development time to the newly announced DLSS 5 model, which has generated quite a stir since its unveiling.
LITERALLY nvidia says not to use framegen if you dont have 60fps w/o it :|
if you have 30 fps, turn MFG on to get "60" its gonna feel worse than 30 because you lack enough actual frame data for it to work properly.
True. However, Nvidia, AMD, and Intel all have their own frame gen technology, and some might be better than others. I am using "FG" and "MFG" as generic terms.
Most recently, Intel XeSS 3 Multi-Frame Generation was launched for everything from Meteor Lake iGPUs to the Arc B580:
