DLSS 4.5 Dynamic MFG Settings: NVIDIA App Guide
On RTX 50, open NVIDIA App → Graphics → your game → Driver Settings → DLSS Override - Frame Generation Mode. Choose Dynamic to follow a frame-rate target or Fixed to keep one multiplier. The game must support the selected mode.
Quick answer
Open the NVIDIA App Graphics tab, choose your game, then use DLSS Override - Frame Generation Mode. Dynamic mode can target Max refresh rate or a Custom number. Fixed mode uses the selected multiplier. Dynamic MFG with V-Sync or frame rate limiters requires the newer NVIDIA App path, 616.64 WHQL or later, and Streamline 2.14 or later.
Settings table
The important DLSS 4.5 Dynamic MFG settings are about target behavior, not only a bigger frame multiplier. Dynamic, Fixed, Max refresh rate, and Custom targets can produce different test results.
| Setting | Where it appears | Best use | Caveat |
|---|---|---|---|
| Dynamic | DLSS Override - Frame Generation Mode | Targets the display refresh rate or a custom frame-rate cap. | Supported with V-Sync or frame limiters only on the newer NVIDIA App path with 616.64 WHQL+ and Streamline 2.14+. |
| Fixed | DLSS Override - Frame Generation Mode | Runs the multiplier selected by the player. | Use this when you want predictable behavior instead of automatic shifting. |
| Max refresh rate | Dynamic mode target | Lets the app synchronize toward the maximum refresh rate of the display. | Best for high-refresh panels when the game can feed enough rendered frames. |
| Custom | Dynamic mode target | Lets the player type a maximum frame-rate target. | The target is not a guarantee if the base game performance is too low. |
| Preset B | DLSS Override - Model Presets | Uses the newer Frame Generation model in selected games. | Look for UI clarity changes, not just average FPS. |
Setup checklist
Confirm an RTX 50 GPU and a compatible game before changing the profile.
- Update the NVIDIA App and install a current Game Ready Driver. For Dynamic MFG with V-Sync or frame limiters, use 616.64 WHQL or later.
- Open Graphics, select your game, then scroll to Driver Settings. Start with a per-game profile so the change only affects that title.
- Find DLSS Override - Frame Generation Mode.
- Choose Dynamic for automatic shifting or Fixed for a selected multiplier.
- If Dynamic is selected, choose Max refresh rate or type a Custom target.
- Launch the game and confirm Frame Generation is enabled in the game menu when required.
- If the Dynamic tooltip still warns about V-Sync or frame limiters, reboot and check the downloaded Streamline version using the instructions below.
Common problems
V-Sync warning still showing? Check Streamline
NVIDIA's September 3 update requires the updated NVIDIA App, driver 616.64 WHQL or newer, and Streamline 2.14 or newer for Dynamic MFG with V-Sync or frame limiters. NVIDIA says the Streamline component downloads automatically after a system reboot.
- Restart after updating the app and driver, then reopen your game's Dynamic setting.
- If the incompatibility tooltip remains, open
C:\ProgramData\NVIDIA\NGX\models\nvngx_config.txtin a text editor. - Find
sl_dlss_g_0and check for version2.14.0or later. Read the value; do not edit it to force compatibility.
To use ordinary 2X Frame Generation instead, select Use 3D app settingin the override and enable FG in the game. To undo an override, restore that game profile's previous setting and restart the game.
How to compare frame rate and responsiveness
Compare one variable at a time. If you are testing Dynamic mode, do not also change resolution, ray tracing, Reflex, V-Sync, frame limits, and game quality presets during the same run. Frame pacing can feel different even when average FPS looks good.
For high-refresh monitors, Max refresh rate is the natural first test. For a more controlled benchmark, Custom can be easier because you decide the target before launching the game. Fixed mode is useful when you want a repeatable multiplier for side-by-side capture. Record the selected mode and target alongside resolution and ray-tracing settings.
Recommended test matrix
Choose a starting point for your display or test. Record the base rendered frame rate separately from the FPS shown with generated frames; they measure different things.
High-refresh display
Start with: Dynamic plus Max refresh rate
Monitor refresh rate, average FPS, base rendered FPS if available, and whether the game can hold the target without large frame-time swings.
Repeatable benchmark
Start with: Fixed multiplier
One scene, one route, one graphics preset, and the exact multiplier. This makes before-and-after captures easier to compare.
Comfort target
Start with: Dynamic plus Custom target
The custom frame-rate number, Reflex state, V-Sync state, and whether input timing feels consistent during camera pans.
UI clarity check
Start with: Preset B where available
Map screens, subtitles, HUD text, menus, and static overlays. NVIDIA highlights UI handling as part of the newer model story.
Repeat the comparison if a driver update or game patch changes the behavior. Profiles can change their available modes or recommended defaults.
When Fixed can be the better answer
Dynamic aims for a display target, but it is not automatically the best choice for every game. If the base frame rate is unstable, a mode that constantly changes multipliers can make the result harder to read. In that case, Fixed mode is often the cleaner first test because the multiplier stays known.
Start with Dynamic when you are tuning for a high-refresh panel and the game already feels responsive. Start with Fixed when you are comparing visual artifacts, measuring latency, capturing video, or checking whether a specific title exposes 4X or 6X correctly. Judge the result by frame pacing, HUD stability, and input feel, not only by the highest number in an overlay.
Understand why 2X, 4X, 6X, Dynamic, and Fixed are not the same thing.

Frequently asked questions
Where are DLSS 4.5 Dynamic MFG settings?
DLSS 4.5 Dynamic MFG settings live in the NVIDIA App Graphics tab. Choose a global or per-game profile, then use DLSS Override - Frame Generation Mode. Select Dynamic, then choose Max refresh rate or a Custom target if the option is available for your setup.
Should I use Dynamic or Fixed mode?
Use Dynamic if your goal is to follow a refresh-rate or frame-rate target. Use Fixed if you want a known multiplier and easier comparison testing between runs.
Why does NVIDIA warn about V-Sync and frame limiters?
Older Dynamic MFG paths warned that V-Sync and frame limiters were not compatible. NVIDIA's newer September 2026 driver note says support requires the new NVIDIA App path, 616.64 WHQL or later, and Streamline 2.14 or later; if the old tooltip remains, the setup is not current.
