DLSS Frame Generation is enabled inside a game’s graphics settings or, for a growing number of titles, via the NVIDIA App’s DLSS Override feature, provided you have a supported RTX 40 Series GPU and Hardware-Accelerated GPU Scheduling turned on in Windows.
Turning on NVIDIA’s frame-smoothing tech can double or triple perceived frame rates in supported games, but the toggle isn’t always sitting right where you’d expect it. The exact path depends on whether the game has the option built in or relies on the newer global override in the NVIDIA App. Either route needs one specific Windows setting active first, and missing that is the single most common reason the option stays grayed out.
The Prerequisite You Cannot Skip: Hardware-Accelerated GPU Scheduling
DLSS Frame Generation requires Hardware-Accelerated GPU Scheduling (HAGS) to be enabled in Windows. Without it, the frame generation toggle will be grayed out or invisible in games, even on a supported RTX 40 Series card.
HAGS lets the GPU manage its own video memory, reducing CPU overhead and enabling the parallel work streams that frame generation relies on. On Windows 11, HAGS is turned on by default. On Windows 10, you need to turn it on manually.
- Press the Windows key, type Graphics settings, and open the result.
- Under Hardware-accelerated GPU scheduling, toggle the setting to On.
- Restart your PC for the change to take effect.
Method 1: In-Game Graphics Settings (The Stable Path)
For games that natively support DLSS Frame Generation — Cyberpunk 2077, Alan Wake 2, Hogwarts Legacy, and dozens more — the toggle lives inside the game’s own graphics menu.
Open the game’s Settings or Graphics menu, locate the DLSS section, and look for a sub-option labeled Frame Generation or DLSS Frame Generation. Switch it to On or Enabled. When it works, you’ll immediately see a smoother motion — the frame rate counter will roughly double while the rendered base frame rate stays the same.
If the option is present but grayed out, the most likely culprits are a disabled HAGS setting or an unsupported GPU. Double-check the HAGS toggle in Windows first.
Method 2: The NVIDIA App DLSS Override Path
NVIDIA’s newer DLSS Override feature, part of the NVIDIA App, lets you force Frame Generation on in certain titles that don’t have a built-in toggle. This works through the DLSS Override – Frame Generation Mode control and a Model Preset selection.
Open the NVIDIA App, go to Graphics, find the game or app you want to configure, and click the DLSS Override section. You can choose between Fixed mode (set a multiplier like 2x or 3x) or Dynamic mode (let the system adjust up to a maximum frame rate you set). NVIDIA recommends using the Dynamic mode with a reasonable Max refresh rate for most users. Under DLSS Override – Model Presets, select Preset B for Frame Generation.
This newer method currently works with a subset of games and requires the latest NVIDIA drivers and NVIDIA App version. NVIDIA’s official announcement confirmed DLSS 4.5 Dynamic Multi Frame Generation support in the app as of June 2026.
Comparisons: Game Settings vs NVIDIA App Override
| Setting Path | Who Can Use It | Best For |
|---|---|---|
| In-Game Graphics Menu | Games with native DLSS FG support | Direct, simple toggle with per-game tuning |
| NVIDIA App DLSS Override | Games supporting DLSS Override | Forcing FG on titles lacking a built-in toggle |
| Fixed Mode (Override) | All DLSS Override titles | Consistent multiplier, good for benchmark runs |
| Dynamic Mode (Override) | All DLSS Override titles | Variable frame rates up to a cap, smoother feel |
| Model Preset B | Override-capable games | The current recommended preset for Frame Gen quality |
DLSS Frame Generation Model Preset Options
The NVIDIA App also exposes DLSS Override – Model Presets, which let you choose between different AI models for various DLSS features. For Frame Generation, the current recommended selection is Preset B. The table below shows the presets available for Frame Generation as of the latest update.
| Preset Label | Use Case | NVIDIA’s Recommended For |
|---|---|---|
| Preset A | Default fallback | General compatibility |
| Preset B | High quality Frame Generation | Frame Generation specifically |
| Preset C | Legacy model | Older games without override support |
| Preset D | Balanced | Performance/quality trade-off (rarely needed) |
What If The Option Is Still Missing Or Grayed Out?
When Frame Generation won’t show up or remains disabled, check these factors in order.
Unsupported GPU. Standard DLSS Frame Generation from NVIDIA requires a GeForce RTX 40 Series card or newer. Older RTX 20/30 cards lack the optical flow accelerator needed for the hardware-accelerated path. Some third-party workarounds exist, but NVIDIA does not support or endorse them, and they can cause instability.
HAGS still off. Even on Windows 11, certain driver updates or Windows features can reset the setting. Open Graphics settings and confirm HAGS is On, then restart.
Game or app version. Frame Generation may only appear in specific game builds or after applying the latest game patch. Check the game’s official update notes to see if DLSS FG support was added.
NVIDIA’s Streamline SDK integration guide also notes that developers should disable Frame Generation during menu screens and scene transitions to prevent artifacts, so the setting may behave differently between menus and actual gameplay.
Final Checklist For DLSS Frame Generation
- Confirmed your GPU is a GeForce RTX 40 Series (or newer) — check in Device Manager if unsure.
- Hardware-Accelerated GPU Scheduling is enabled in Windows Graphics settings (restart required).
- Updated to the latest NVIDIA drivers via the NVIDIA App or GeForce Experience.
- For in-game method: open game Settings > Graphics > DLSS section > turn on Frame Generation.
- For NVIDIA App override: open NVIDIA App > Graphics > select game > configure DLSS Override > set Frame Generation Mode and Model Preset B.
- If the option remains grayed out, verify the game actually lists DLSS FG in its official spec sheet and that no pending game update exists.
