NVIDIA responded to our follow-up questions on its DLSS 4.5 announcement . There had been some lingering questions on what features are available across the GeForce RTX lineup, which are exclusive to the latest RTX 50-series, and exactly how some of those features work.

1) Our first question to NVIDIA was whether Dynamic Multi Frame Generation worked in some limited form on RTX 40-series / Ada, at least to automatically switch between 2x FrameGen and no FrameGen. NVIDIA says that Dynamic Multi FrameGen only works on the RTX 50-series, there's not even a limited version of it on the RTX 40-series.

2) Our next question was to understand how the 240 FPS mode picked the default target FPS, whether it did so by looking at the supported display modes reported by the monitor to Windows, or if it's always default to 240 FPS even when connected to a display with lower refresh rates, such as 144 Hz or 60 Hz. NVIDIA says that since DLSS Overrides are a user-initiated feature, the user has full control. You first have to select "Dynamic" in the Frame Generation Mode section of DLSS Override, and in the Target FPS dropdown, you are presented with two choices. The "Max refresh rate" option sets the target FPS to the maximum refresh rate supported by the monitor, while the "Custom" option lets you manually specify a target FPS value.
