Nvidia is releasing new graphics features in the Nvidia app on March 31: Users can then increase the frame rate by up to six times via Frame Generation – previously, four times Frame Generation was the maximum. Also new will be the ability to dynamically set the Frame Generation factor so that it automatically maintains a targeted frame rate.
The innovations are part of the DLSS 4.5 AI suite, whose first features with improved upscaling Nvidia had already released at the beginning of the year. Nvidia is now releasing the remaining features at the end of March, the company announced. To use the new functions on March 31, you need to sign up for the beta of the Nvidia app. To do this, you just need to check a box in the app settings.
AI images between real frames
Frame Generation is an AI process in which Nvidia graphics cards insert images between rendered frames using motion vectors. Originally, only double Frame Generation was available: Here, the RTX graphics card inserts an AI-generated image between two rendered frames. The resulting frame rate is thus doubled after deducting the performance costs necessary for Frame Generation.
However, users do not fully benefit from the actual advantages of a higher frame rate with these "artificial frames": Although the image looks smoother, the input lag does not decrease, but usually increases slightly. In addition, interpolated frames can exhibit artifacts. Rule of thumb: For Frame Generation to make sense at all, you should have around 50 to 60 FPS before activating the function. At lower frame rates, the AI artifacts of the "fake frames" are more clearly visible.
Meanwhile, you can not only double FPS via Frame Generation, but even triple and quadruple them. The graphics card simply inserts more AI images between two rendered images. With DLSS 4.5, you can even multiply the FPS by six – but this only makes sense if you have a monitor with a very high refresh rate – i.e., 360 Hertz or higher.

Dynamic Frame Generation
On other monitors, a new function is also practical, which dynamically adjusts the number of generated frames to the game action. Depending on the output frame rate, double, triple, or up to six times frames are interpolated to completely fill the refresh rate of a monitor or a frame rate manually set by the user. This way, the Nvidia GPU ensures on the one hand that a targeted frame rate is kept stable and at the same time fewer unnecessary frames are generated, which would drag down the actual output frame rate.
If you play on a 240 Hz monitor with six-fold Frame Generation, you can achieve a maximum of 40 "real frames" (in practice only 37, because Nvidia Reflex sets the refresh rate to 224 in this scenario when Frame Generation is activated) – even if the PC would fundamentally be capable of achieving more. In easily renderable scenes, dynamic Frame Generation could automatically switch to four-fold Frame Generation, for example, to render 60 (or rather 56) real frames before AI frames are inserted.
