How to enable DLSS 4.5 on a supported GPU?

To enable DLSS 4.5 on a supported GPU, make sure your NVIDIA RTX graphics card is compatible, install the latest NVIDIA Game Ready or Studio Driver, update the game or application that supports DLSS 4.5, enable DLSS from the in-game graphics settings, and select the desired DLSS mode for the best balance of performance and visual quality.

With DLSS 4.5, NVIDIA focuses on improved temporal stability, reduced ghosting, better edge reconstruction, and more accurate texture details. These improvements are only available on supported RTX GPUs and in games or applications that officially integrate DLSS 4.5.

Now, let’s enable it!

Step 1: Confirm Your GPU Supports DLSS 4.5

The first and most important step is checking GPU compatibility. DLSS 4.5 requires an NVIDIA RTX GPU with Tensor Cores. This generally includes RTX 20 series, RTX 30 series, RTX 40 series, and newer supported models.

To check your GPU model, open the NVIDIA Control Panel or use Task Manager on Windows. Under the Performance tab, you can view the GPU name. If your system uses an older GTX graphics card, DLSS will not be available because those cards lack Tensor Cores.

It is also important to confirm that your specific GPU model is supported by the DLSS 4.5 implementation in the game you want to play. Some games may limit advanced DLSS features to newer RTX generations.

Step 2: Update NVIDIA Graphics Drivers

DLSS 4.5 will not appear unless your system is running a compatible NVIDIA driver. NVIDIA typically enables new DLSS versions through Game Ready Drivers or Studio Drivers.

Open GeForce Experience or visit the NVIDIA driver update section and install the latest available driver. During installation, it is recommended to select a clean installation to avoid conflicts with older driver profiles.

After updating, restart your computer. This ensures that all driver components related to DLSS, AI upscaling, and Tensor Core acceleration load correctly.

Step 3: Update the Game or Application

Even if your GPU and drivers are ready, DLSS 4.5 must be supported at the application level. Developers integrate DLSS directly into their games or software using NVIDIA SDKs.

Open your game launcher, such as Steam, Epic Games Launcher, or another platform, and check for updates. Make sure the game version explicitly supports DLSS 4.5 or the latest DLSS implementation provided by the developer.

Without the correct game update, the DLSS 4.5 option will not appear in graphics settings, regardless of your hardware.

Step 4: Launch the Game and Open Graphics Settings

Once everything is updated, launch the game and navigate to the graphics settings or video settings menu. DLSS options are usually found under advanced graphics or performance-related settings.

Look for an option labeled NVIDIA DLSS, DLSS Super Resolution, or similar. If DLSS 4.5 is supported, the setting will be visible and selectable.

If you do not see DLSS at all, double-check that the game is running in DirectX 11, DirectX 12, or Vulkan, as some APIs are required for DLSS to function properly.

Step 5: Enable DLSS 4.5 and Choose a Mode

After locating the DLSS option, enable it and choose the most suitable mode. DLSS 4.5 usually offers several quality presets that control how aggressively the image is upscaled.

Quality mode focuses on visual clarity while still improving performance. Balanced mode offers a mix of performance and image quality. Performance mode prioritizes higher frame rates, especially at 4K resolutions. Ultra Performance mode is designed for very high resolutions and demanding workloads.

Select a mode based on your screen resolution, GPU power, and personal preference. For most users, DLSS Quality mode provides the best visual results.

Step 6: Apply Settings and Restart if Required

Some games require a restart after enabling DLSS to ensure AI reconstruction features are applied properly. Apply the settings and restart the game if prompted.

After restarting, return to the graphics settings to confirm that DLSS 4.5 remains enabled. You should also notice improved frame rates and smoother performance during gameplay.

Step 7: Verify DLSS 4.5 Is Working Correctly

To ensure DLSS 4.5 is active, enable an in-game FPS counter or use third-party tools like NVIDIA FrameView. Compare performance with DLSS turned off and on.

You should see a noticeable increase in frame rate without a significant loss in visual quality. In many cases, image stability and sharpness may even appear improved due to advanced AI reconstruction.

FAQs

What is DLSS 4.5?

DLSS 4.5 is an advanced AI-based upscaling technology from NVIDIA that improves performance and image quality using deep learning models and Tensor Cores on RTX GPUs.

Which GPUs support DLSS 4.5?

DLSS 4.5 is supported on NVIDIA RTX GPUs that include Tensor Cores. Compatibility may vary depending on the game and GPU generation.

Do I need an internet connection for DLSS 4.5?

An internet connection is only required to download drivers and game updates. DLSS itself runs locally on your GPU.

Can DLSS 4.5 be enabled globally?

DLSS must be enabled individually within each supported game or application. There is no global system-wide DLSS toggle.

Does DLSS 4.5 reduce image quality?

When configured correctly, DLSS 4.5 maintains high visual quality and often improves stability and sharpness compared to native resolution with lower frame rates.
