Behind DLSS 4.5, NVIDIA is no longer content with adding FPS. With new dynamic and fixed modes directly controllable via the NVIDIA App, Frame Generation becomes an adjustable parameter, capable of following the refresh rate or imposing constant behavior. A discreet development in appearance, but which profoundly transforms the way in which images are generated, displayed… and felt in-game.
Activation via NVIDIA App and 595.97 driver
Nvidia details on Bilibili the activation of DLSS 4.5 in two variants focused on frame generation: a dynamic mode with refresh ceiling and a fixed mode capable of reaching a factor of 6x. The settings are made through the new NVIDIA App application, in beta version, and require at least the GeForce Game Ready 595.97 WHQL driver.
You must first check “ Choose to participate to test beta or experimental features ” in “ Settings—about ”, then install the NVIDIA App beta update. Next, update the driver to GeForce Game Ready 595.97 WHQL (or higher) to unlock the DLSS 4.5 options.
In the “Graphics” tab, you can target a specific game via “Program Settings” or apply a global setting to all supported titles. The “Image generation mode – Optimized DLSS” menu then offers two logics: “Dynamic” or “Fixed”.
Dynamic mode: synchronized or custom ceiling
In “Dynamic”, the user can select “Maximum refresh rate” to align the FPS target with the native frequency of the monitor, in order to preserve sharpness in motion. A “Custom” option allows you to enter a specific FPS cap and adjust a maximum multiplier for DLSS 4.5 multi-frame generation.
Mode fixe : génération jusqu’à 6x
In “Fixed”, NVIDIA App directly exposes the response multiplier, with an adjustment up to 6x. This mode prioritizes a constant generation factor, useful for stabilizing the frame rate in compatible titles that tolerate controlled additional rendering latency.
The positioning is clear: “Dynamic” seeks the balance between perceived clarity and intelligent capping, “Fixed” pushes the FPS to the maximum on heavy scenes. Deploying in NVIDIA App, rather than through scattered panels, accelerates adoption on the gamer side and reduces integration time on the studio side, provided the DLSS 4.5 compatibility list keeps pace with the drivers.
