How to override DLSS Frame Generation and Multi Frame Generation
In a game that already supports DLSS Frame Generation, NPI can force the newer frame generation model and the number of generated frames. Set DLSS-FG - Enable DLL Override (0x10E41E03) to On, choose DLSS-FG - Forced Mode (Fixed or Dynamic) and the frame count, then Apply. NVIDIA says Multi Frame Generation needs an RTX 50 GPU and Frame Generation needs RTX 40 or newer. NPI cannot add frame generation to a game without it. Smooth Motion is the driver feature that works in more games.
You need
- GPU
- RTX 40 for FG, RTX 50 for MFG
- Driver
- 595.97 or newer for dynamic MFG
- Game
- with DLSS Frame Generation
- Time
- 5 minutes
Which GPUs can use what
| GPU | DLSS Frame Generation | Multi Frame Generation | Smooth Motion |
|---|---|---|---|
| RTX 50 | Yes | Yes, fixed and dynamic | Yes |
| RTX 40 | Yes | No, per NVIDIA | Yes |
| RTX 30 and 20 | No | No | See the Smooth Motion page |
This is NVIDIA’s stated support. OFFICIAL · NVIDIA announcements We could not test any GPU. On RTX 30 and 20 there is no DLSS Frame Generation, so look at Smooth Motion and the other tools compared.
The frame generation settings in NPI
| Setting | ID | Values |
|---|---|---|
| DLSS-FG - Enable DLL Override | ↗ | Off, On (driver supplies the library) |
| DLSS-FG - Forced Preset Letter | ↗ | N/A, recommended, Preset A (default), B (UI focus), C (performance focus), D, E |
| DLSS-FG - Forced Mode | ↗ | N/A, Fixed (2), Dynamic (4) |
| DLSS-MFG - Fixed Frame Generation Count | ↗ | N/A, 2x to 6x (values 1 to 5) |
| DLSS-MFG - Dynamic Frame Generation Count | ↗ | N/A, up to 2x to up to 6x. Driver 595.97 and newer |
| DLSS-MFG - Target Dynamic Frame Rate | ↗ | N/A, Max Refresh Rate, or 60 FPS and up. Driver 595.97 and newer |
| DLSS-FG - Scene Auto Change Detection | ↗ | Default, Disable, Detection Method |
| DLSS-FG - Full-Screen Menu Detection | ↗ | N/A, Allow, Force Enable |
NVIDIA does not document what most rows do beyond their names, and we have not tested them. The two menu threshold rows (↗ and ↗) hold raw floating-point numbers. CODE · NPI value lists
Step by step: set MFG for one game
Open the game's profile
Use the game’s own profile. Add the game if needed.
Turn on the FG override
Set ↗ to On.
Choose the mode
Set ↗ to Fixed or Dynamic.
Choose the count
Apply and check in the game
Click Apply Changes, start the game and check that frame generation is on in its menu. The DLSS indicator helps confirm what is running.
What published tests found
We have no GPU, so these are other people’s numbers. REPORTED · Tom's Hardware, RTX 5070
PC latency by frame generation multiplier, RTX 5070
The first generated frame adds the most latency. Going from 4X to 6X added nothing measurable.
Average PC latency, lower is better
Show the data
| Item | ms | Setup |
|---|---|---|
| Off | 35.0 | |
| 2X | 46.6 | |
| 4X | 53.2 | |
| 6X | 52.6 |
Digital Foundry measured 51.0, 55.5 and 57.3 ms at 2X, 3X and 4X on an RTX 5080. PCGamesN found 3X and above laggy with mouse and keyboard from a base near 60 FPS, with about 60 ms at 4X and up to 68 ms for dynamic MFG. Tom’s Guide showed a 27 FPS base turning into 123 FPS on screen at about 84 ms. REPORTED · Digital Foundry, PCGamesN, Tom's Guide NVIDIA publishes output targets, 3X for up to 180 FPS and 4X for 240 and above, and we found no NVIDIA document giving a minimum base frame rate. OFFICIAL · NVIDIA app guidance
Fixed or dynamic MFG?
Dynamic MFG switches multipliers to hit a target or the display refresh rate and is limited to RTX 50. We found no head-to-head test of latency, and the base frame rate matters more than the mode.
Frame generation on RTX 40
NVIDIA states the override rows for Multi Frame Generation are meant for RTX 50. We could not check what an RTX 40 does with a forced count, so we do not say.
Frame generation, G-SYNC, V-Sync and frame caps
Limiter and V-Sync support with dynamic MFG needs driver 616.64 or newer and Streamline 2.14 or later in the game. OFFICIAL · NVIDIA, E035 Driver 616.56 fixed a bug where the frame rate could exceed the V-Sync limit at 3X or higher in two games. OFFICIAL · release notes See the G-SYNC recipe and frame rate limiter. Players have also reported stutter with frame generation and G-SYNC, which we could not reproduce. COMMUNITY · forum reports
Frame generation presets: A, B and C
NPI lists Preset A as default, B as UI Focus and C as Performance Focus. NVIDIA describes a Performance Mode, preset C, as up to 35 percent faster on an RTX 5060 in its own claim, which we have not verified. OFFICIAL · vendor claim See DLSS presets.
Problems and fixes
| Symptom | Likely cause | What to try |
|---|---|---|
| Greyed out in the NVIDIA App | GPU or game does not support it | Check the support table. NPI shows rows on any GPU, but that does not mean the game uses them. |
| Game ignores the forced count | The game or its library does not honour the override | Check the exe in the profile and the game version. |
| HUD or menus glitch | Menu detection | Try the full-screen menu detection row. |
| Stutter with VRR | Reported interaction, not tested by us | Follow the G-SYNC recipe and test a cap. |
| Crash at launch | A bad value in the profile | Revert the rows to N/A and Off. |
See NPI not working for broader fixes.
Undo
Set the override back to Off, the forced mode and counts back to N/A, and click Apply Changes. Or import a backup, see undo and reset.
Questions people ask
Can I force Multi Frame Generation on an RTX 40?
NVIDIA states that Multi Frame Generation is for RTX 50 GPUs. NPI shows the rows on any GPU, but we could not test an RTX 40 and cannot say whether the count is ignored or rejected.
Does frame generation add input lag?
Yes. Published tests show PC latency rising when frame generation is switched on, for example from 35.0 ms to 46.6 ms at 2X on an RTX 5070. Each extra generated frame after the first adds only a few milliseconds.
Fixed or dynamic MFG, which is better?
Fixed gives a steady multiplier. Dynamic switches the multiplier to hold a target frame rate or the display refresh rate. We have no own comparison, and published tests show latency depends mostly on the base frame rate.
Can NPI add frame generation to any game?
No. The override replaces how a game that already ships Frame Generation behaves. Smooth Motion is a separate driver feature that works in more games.
