DLSS Frame Generation Explained: GPUs, Settings and Is It Worth It (2026)

DLSS Frame Generation uses AI on NVIDIA RTX graphics cards to create extra frames between the ones your GPU actually renders, so the game looks far smoother than its real frame rate. It needs an RTX 40 or RTX 50 series card. RTX 50 cards can also generate several frames per rendered frame, up to 6X with DLSS 4.5. It makes motion smoother, but it does not make the game respond faster to your inputs, so it works best when your frame rate is already decent.

How DLSS Frame Generation works

A normal GPU renders every frame from scratch. With Frame Generation turned on, the GPU still renders frames the usual way, but between each pair of real frames it inserts one or more AI-generated frames. The AI model, running on the card’s Tensor Cores, looks at the two real frames on either side, the motion of objects and the game’s motion data, and predicts what the in-between image should look like.

Because the generated frame sits between two real ones, the game has to hold back the newest real frame for a moment before showing it. That is why Frame Generation always adds a little input latency, and why NVIDIA pairs it with Reflex, its latency-reduction technology. In games that support DLSS Frame Generation, Reflex is switched on with it.

Frame Generation is separate from DLSS Super Resolution, the upscaler that renders at a lower resolution and rebuilds a sharper image. Most games let you use the two together, which is where NVIDIA’s largest frame-rate multipliers come from.

Which GPUs support DLSS Frame Generation?

• RTX 50 series: everything. Standard Frame Generation (2X), Multi Frame Generation up to 4X from DLSS 4, and the DLSS 4.5 additions: a 6X mode and Dynamic Multi Frame Generation.
• RTX 40 series: standard Frame Generation, one generated frame per rendered frame (2X). DLSS 4 also gave RTX 40 cards an updated Frame Generation model that uses less video memory.
• RTX 20 and RTX 30 series: no DLSS Frame Generation. These cards still get DLSS Super Resolution, DLAA and Ray Reconstruction, including the newer transformer models.
• GTX cards and non-NVIDIA GPUs: no DLSS at all.

If you have an RTX 20 or 30 card and want frame generation, AMD’s FSR 3 frame generation is vendor-neutral and works on a much wider range of GPUs in the games that support it.

DLSS 3, DLSS 4 and DLSS 4.5: what changed

NVIDIA’s version numbers bundle several features together, which causes a lot of confusion. Here is what each one added for frame generation specifically.

• DLSS 3 (2022): introduced Frame Generation with the RTX 40 series. One AI frame for every rendered frame.
• DLSS 3.5 (2023): added Ray Reconstruction, an AI denoiser for ray tracing. It did not change Frame Generation. Articles that talk about “DLSS 3.5 Frame Generation” usually mean DLSS 3 Frame Generation running alongside 3.5’s Ray Reconstruction.
• DLSS 4 (January 2025): launched with the RTX 50 series and added Multi Frame Generation, which creates up to three additional frames per rendered frame, a 4X multiplier. It is RTX 50 only. The same release moved Super Resolution, Ray Reconstruction and DLAA to a transformer AI model for all RTX cards, and gave RTX 40 and 50 cards a lighter Frame Generation model.
• DLSS 4.5 (announced January 2026, frame generation features released March 31, 2026): added a 6X mode, which generates five frames for every rendered one, and Dynamic Multi Frame Generation, which automatically changes the multiplier to match your monitor’s refresh rate, adding frames in heavy scenes and fewer in light ones. Both are RTX 50 only. DLSS 4.5 also brought a second-generation transformer model for Super Resolution to all RTX GPUs.

How to turn on DLSS Frame Generation

1. Update your driver. Install the latest NVIDIA Game Ready Driver. DLSS 4.5’s Dynamic Multi Frame Generation and 6X mode need driver 595.97 or newer.
2. Turn on Hardware-accelerated GPU scheduling. In Windows, open Settings, go to System, then Display, then Graphics, open the advanced or default graphics settings, and switch on Hardware-accelerated GPU scheduling. Restart afterwards. DLSS Frame Generation requires it, and the in-game option is often greyed out without it.
3. Enable it in the game. Open the game’s graphics settings and look for “DLSS Frame Generation” or “Frame Generation.” On RTX 50 cards, supporting games show a multiplier choice such as 2X, 3X or 4X. Many games also turn on Reflex automatically at this point.
4. Or use the NVIDIA app override. For games that support DLSS but not the newest modes, the NVIDIA app can override them. In the app, go to Graphics, select the game under Program Settings, and use the DLSS Override options. This is how RTX 50 owners get Multi Frame Generation, 6X and Dynamic mode in games that only shipped with the original Frame Generation.
5. Check it is working. The NVIDIA app overlay, opened with Alt+Z, can show DLSS statistics so you can confirm which DLSS features and models are active.

Is Frame Generation worth it?

It depends on what you play and the frame rate you start from.

• Great for: single-player games, especially heavy ray-traced or path-traced ones, and high-refresh monitors you cannot otherwise fill. Going from about 70 real frames to 140 displayed frames looks dramatically smoother.
• Weak for: competitive shooters and fighting games. Generated frames do not react to your input, so responsiveness still matches your real frame rate, plus a small delay. Most players turn it off when every millisecond counts.
• Bad when your base frame rate is low. If the game only renders 25 or 30 real frames per second, Frame Generation can make the counter look high while the game still feels sluggish, and visual artifacts become easier to see because there is more motion between real frames. A common rule of thumb is to get to around 60 real frames per second first, using DLSS Super Resolution or lower settings, and then add Frame Generation on top.

What artifacts look like: fast-moving HUD elements, text and the edges of quickly moving objects can show brief smearing or ghosting on generated frames. The newer DLSS 4 and 4.5 models reduce this, and it is much harder to notice at high frame rates.

Frequently asked questions

Does DLSS Frame Generation work on RTX 30 series cards?

No. NVIDIA limits DLSS Frame Generation to RTX 40 and RTX 50 series cards. RTX 30 owners can use DLSS Super Resolution, or AMD FSR 3 frame generation in games that support it.

Does Frame Generation increase input lag?

Slightly, yes. The game has to hold each real frame briefly so it can place AI frames in between. NVIDIA Reflex offsets much of that delay, which is why the two are used together, but Frame Generation never makes a game more responsive than its real frame rate.

What is the difference between Frame Generation and Multi Frame Generation?

Frame Generation creates one AI frame per rendered frame (2X) and works on RTX 40 and 50 cards. Multi Frame Generation, added in DLSS 4, creates up to three (4X), and DLSS 4.5 raised the maximum to five (6X). Both multi-frame modes are RTX 50 only.

Why is the DLSS Frame Generation option greyed out?

The usual causes are an unsupported GPU (RTX 30 or older), Hardware-accelerated GPU scheduling switched off in Windows, an outdated driver, or a game that does not support Frame Generation.

Should I use Frame Generation with DLSS Super Resolution?

Usually, yes. Super Resolution raises your real frame rate, which improves responsiveness and gives Frame Generation more information to work with. Combining them is how NVIDIA’s headline frame-rate multipliers are reached.
