DLSS can lower the resolution a game renders internally while still outputting an image at your chosen display resolution; it can also generate extra frames to raise the displayed frame rate. These are separate features in NVIDIA’s DLSS suite, and support and results vary by game, GPU, and settings.
What DLSS changes in a game
DLSS—Deep Learning Super Sampling—is a suite of NVIDIA neural-rendering features for GeForce RTX graphics cards, not one switch that performs a single task. Depending on what a game supports and which options you enable, DLSS may reconstruct an image, generate frames, improve ray-traced image reconstruction, or apply anti-aliasing. NVIDIA outlines the feature family in its DLSS developer overview.
Internal render resolution versus output resolution
A game’s internal render resolution is the resolution at which it initially renders scene information. Its output resolution is the resolution of the image sent to the display. With DLSS Super Resolution, the game renders at a lower internal resolution than the output target, then reconstructs an image for that target using image samples, motion data, and information from earlier frames. For example, a game can output at a selected high resolution without conventionally rendering every output pixel at that resolution.
So, does DLSS lower resolution? Super Resolution lowers the internal rendered input relative to the output target; it does not necessarily lower the resolution sent to your monitor. The reconstructed image can differ in clarity or stability from a native-resolution render, and the result depends on the game and settings.

What each DLSS feature does
| Feature | What it changes | How to think about it |
|---|---|---|
| Super Resolution | Reconstructs a higher-resolution output from lower-resolution input. | Can reduce conventional rendering work while targeting your chosen output resolution. |
| Frame Generation | Creates additional frames between traditionally rendered frames. | Can increase displayed frame rate; generated frames are not independently simulated and conventionally rendered by the game engine. |
| Multi Frame Generation and Dynamic Multi Frame Generation | Generate frames using NVIDIA’s newer frame-generation options; the number of frames and availability depend on GPU and game support. | Not simply another name for Super Resolution. Check the specific game and GPU. |
| Ray Reconstruction | Uses AI reconstruction for ray-traced or path-traced scenes, replacing traditional hand-tuned denoisers in NVIDIA’s description. | Primarily an image-reconstruction and denoising technique, not an upscaling or frame-generation mode. |
| DLAA | Applies AI anti-aliasing at native resolution. | Distinct from upscaling lower-resolution input with Super Resolution. |
NVIDIA describes these features on its DLSS technology page. A game may offer only some of them, or may not support DLSS at all.
Does DLSS increase FPS?
It can, but the mechanism matters. Super Resolution can reduce the GPU work needed for conventional rendering by starting from fewer pixels and reconstructing the output. Frame Generation can raise the displayed frame rate by inserting generated frames between traditionally rendered ones. The displayed frame count is therefore not the same as the number of frames the game engine simulated and rendered independently.

Neither feature guarantees a particular FPS increase, image quality, latency, or feel. Outcomes depend on the game’s implementation, GPU, graphics settings, output resolution, and performance before enabling DLSS. When comparing settings, distinguish conventionally rendered FPS from displayed FPS, and consider image clarity, artifacts, latency, and frame pacing as well as the headline frame-rate number.
How to interpret NVIDIA’s performance figures
NVIDIA said in 2025 that “For games and apps, DLSS 4 with Multi Frame Generation, Ray Reconstruction, and Super Resolution multiplies frame rates by up to 8X over brute-force rendering, and boosts frame rates by up to 1.7X when upgrading from Frame Generation to Multi Frame Generation.” These are NVIDIA’s vendor-reported maximum comparisons for the stated combined feature configuration, not independent benchmark results or expected gains for every game and GPU.

Check whether your GPU and game support the feature
Compatibility differs by feature and GPU generation. NVIDIA’s current feature matrix lists Super Resolution for GeForce RTX 20, 30, 40, and 50 series, while Frame Generation and Multi Frame Generation have narrower support. A GPU that supports one DLSS feature does not necessarily support them all, and a compatible GPU alone does not ensure that a particular game offers the feature.
- Check the graphics or display settings in the specific game for the DLSS options it implements.
- Compare the listed feature with NVIDIA’s current DLSS feature matrix for your GPU generation.
- For game-specific availability and NVIDIA’s guidance, consult NVIDIA’s DLSS questions and answers.
When deciding between options in a supported game, assess the internal resolution relative to the output target, image clarity and stability, conventional versus generated FPS, latency and frame pacing, and whether both the game and GPU support the chosen feature. There is no universal best DLSS mode established for every game and system.
