How to Enable DLSS 4 in Unreal Engine 5 (and Use It with Movie Render Queue)

“I installed the DLSS plugin, but why is Frame Generation missing in Movie Render Queue?”

If you have asked yourself this question after setting up NVIDIA’s DLSS 4 in Unreal Engine 5, you are not alone. This is one of the most common points of confusion for 3D artists. The quick answer is simple: Frame Generation was built to smooth out live viewports and interactive applications, not offline rendering tools. Movie Render Queue (MRQ) calculates every single frame at full quality, so AI frame generation simply does not apply there.

However, you can still use several DLSS 4 features to speed up both your live viewport and your offline renders. In this guide, iRender breaks down how DLSS 4 works in UE5, how to set up the plugin step by step, and what you can actually use inside MRQ. 

Yes, you can enable DLSS 4 in Unreal Engine 5 using NVIDIA’s official engine plugins. When working in the active viewport or playing an interactive walkthrough, you can use the complete DLSS 4 feature suite. This includes Super Resolution, Ray Reconstruction, Frame Generation, and the new Multi Frame Generation (MFG).

When you switch to Movie Render Queue for final offline rendering, the capabilities change. MRQ only uses DLSS Super Resolution to render frames at a lower internal resolution and upscale them cleanly. Frame Generation and Multi Frame Generation are disabled in MRQ by design.

It is also worth noting that Multi Frame Generation requires hardware support found specifically on RTX 50 series graphics cards like the RTX 5090.

The DLSS 4 plugin for Unreal Engine combines several distinct AI rendering tools into a single package. Here is how each feature functions and the minimum graphics hardware required:

Before starting, make sure your Unreal Engine project is configured to run on DirectX 12, as DLSS hardware features require it.

1. Download the Plugin: Visit the NVIDIA Developer portal and download the DLSS plugin archive that matches your exact Unreal Engine version (for example, UE 5.5 or UE 5.7).
2. Copy the Plugin Files: Extract the downloaded folder. Copy the DLSS plugin folders into your project’s Plugins directory (create a Plugins folder in your project root if one does not exist).
3. Enable in Editor: Open your project, go to Edit > Plugins, and search for “DLSS” in the search bar. Check the boxes for NVIDIA DLSS, NVIDIA Streamline, and NVIDIA DLSS Movie Render Queue Support.
4. Restart the Editor: Relaunch Unreal Engine 5 to finalize the installation.

Once the plugins are active, turn on DLSS directly in your viewport:

1. Click the Viewport Options arrow (top-left corner of the viewport).
2. Go to Screen Percentage or the DLSS menu.
3. Pick a Super Resolution mode (Quality, Balanced, or Performance).
4. Turn on Ray Reconstruction if you use Ray Tracing or Lumen to clear up noisy reflections.
5. Turn on Frame Generation or Multi Frame Generation (requires an RTX 40 or RTX 50 series card).

To check your frame rate, press the tilde key (~) and type stat fps. Keep in mind that while Frame Generation boosts your FPS count on screen, it does not make mouse movement or controls feel faster.

Movie Render Queue works completely differently from the viewport. Since offline rendering saves image sequences frame by frame, fake AI frames just don’t fit into the workflow.

You can add the NVIDIA DLSS setting directly inside your MRQ job. This lets Unreal render at a lower resolution (like 1080p) and upscale it to 4K for the final output. It is a great way to cut down render times on heavy ray-traced scenes while keeping the image sharp. 

Frame Generation needs real-time user input and movement to guess the frames in between. Because MRQ renders exact camera positions for every frame on disk, Unreal automatically turns Frame Generation off.

Users on the NVIDIA Developer forums report that Ray Reconstruction still doesn’t run properly during MRQ offline renders in Unreal Engine 5.7. If you are rendering with Path Tracer or heavy ray tracing, stick to Path Tracer denoising or higher anti-aliasing sample counts to get clean shots.

Even when following setup steps carefully, you might run into a few technical hiccups while configuring DLSS inside Unreal Engine. Here are the most common issues artists encounter and how to quickly resolve them:

• The DLSS Plugin Does Not Show Up: If the plugin menu is empty, double-check where you pasted the plugin files. Plugin versions are strictly tied to specific engine builds, meaning a folder compiled for UE 5.4 will not load or work inside UE 5.7.
• Frame Generation Is Greyed Out: If you cannot toggle this setting, your system is missing a key requirement. First, verify that your graphics card supports it (standard Frame Generation needs an RTX 40 series GPU, while Multi Frame Generation requires an RTX 50 series card). Second, make sure your Project Settings are set to run on DirectX 12 instead of DirectX 11.
• Engine Crashes When Enabling Streamline: A sudden crash loop right after turning on Streamline usually points to a graphics driver issue. Update your NVIDIA drivers to the latest version. If Unreal still crashes on startup, manually disable Frame Generation in your project’s DefaultEngine.ini file and confirm that your plugin package matches the exact engine version recommended in the release notes. 

If you are developing interactive walkthroughs, real-time archviz presentations, or virtual production sets, testing Multi Frame Generation on an RTX 50 series card shows you if high-refresh-rate delivery is feasible for your client. Buying brand-new hardware just to benchmark a single feature is rarely practical if your local workstation is still running an RTX 30 or RTX 40 series GPU. Instead, renting a powerful cloud desktop equipped with a dedicated RTX 5090 (32GB VRAM) by the hour allows you to test real-world frame rates on actual client projects without upfront capital investment. 

iRender gives you full administrator access to a remote Windows machine (IaaS model). You can freely install your exact Unreal Engine version, set up the DLSS 4 plugin, and tweak project settings just like on your local workstation. Standard SaaS render farms cannot run real-time interactive apps or custom plugin setups, so having full desktop control is essential when testing DLSS 4.

For Unreal Engine, the ideal setup is iRender’s GPU Cloud Workstation 3i server package, which comes with a single RTX 5090 (32GB GDDR7 VRAM). Since Unreal Engine relies heavily on a single powerful GPU for viewport interaction and Movie Render Queue processing, a single RTX 5090 gives you maximum performance while keeping rental costs low.

Here are a few quick tips to get the most out of your cloud setup:

• Initial shader compilation takes time: Remote servers charge for active power-on time, so save a machine image once your plugins and shaders are set up. You can reload this image in future sessions without wasting time reinstalling.
• Measure FPS with in-engine tools: Network streams carry natural remote desktop latency. Always check real-time frame rates using the stat fps command inside Unreal Engine rather than judging smoothness through the remote desktop window.
• Offline rendering gains: For final Movie Render Queue outputs, render speeds improve thanks to the raw processing power and massive 32GB VRAM of the RTX 5090, not AI frame generation.

Watch our video tutorial to see how Unreal Engine performs on iRender’s cloud workstations:

1. Does DLSS Frame Generation work in Movie Render Queue?

No. The official NVIDIA DLSS plugin for Movie Render Queue only supports Super Resolution upscaling. Frame Generation and Multi Frame Generation are designed strictly for real-time viewports and packaged interactive applications.

2. Do I need an RTX 5090 for DLSS 4 in Unreal Engine?

No. Super Resolution, DLAA, and Ray Reconstruction work on all RTX GPUs starting from the RTX 20 series. Frame Generation works on RTX 40 series cards and newer. You only need an RTX 50 series card like the RTX 5090 if you want to use Multi Frame Generation.

3. Why is DLSS Frame Generation greyed out in my Unreal project?

Frame Generation will appear greyed out if your graphics card is older than an RTX 40 series, if your project is running under DirectX 11 instead of DirectX 12, or if the NVIDIA Streamline plugin failed to load properly.
