DLSS 4 Now Works with Unreal Engine 5.6, Using Up to 20% Less VRAM and Improving FPS and Ray Tracing
NVIDIA has been adding artificial intelligence to almost everything it touches, and DLSS 4 is no exception. This time, however, the update goes further. It’s not just about adding more technology, but about balancing power and efficiency, allowing developers to push their projects further without using too many resources.
The integration with Unreal Engine 5.6 is not just a simple upgrade. The DLSS 4 plugin is designed to work directly with the performance improvements already built into this engine version, such as better memory management and improved rendering channels. Everything fits together as if it were custom-made. This has a direct impact: smoother performance, less power use, and stronger visual results, even in complex environments.
Better Performance, Lower Memory Use
What’s interesting is how it achieves this. Instead of using the usual local filters, NVIDIA uses a Transformer neural network. This lets it analyze the entire frame and understand how all elements relate to each other. The result is not just better image quality but also a noticeable memory saving of 15 to 20 percent. In practice, this means more freedom to load large textures, move heavy scenes, or simply have more flexibility without crashing the system.
The system also includes a feature called multi-frame generation. It can create extra images between real frames, predicting what comes next. It might sound like magic, but it’s actually AI-based forecasting. The benefit? More frames per second (FPS) without putting extra strain on the GPU.
Enhanced Ray Tracing and Broader Compatibility
Ray tracing also benefits from DLSS 4. It uses data from high-quality offline renderings to reconstruct scenes. This makes reflections, lighting, and shadows much more realistic without lowering performance like before. In fact, some developers say that in scenes with dynamic lighting, visual improvements can reach 30 to 50 percent.
The best part is that you don’t need the latest system to enjoy these benefits. While Unreal Engine 5.6 is needed to unlock the full potential of the plugin, it’s also compatible with version 5.2 and above. This means even systems with fewer resources can still take advantage of it.
DLSS 4 might not sound as groundbreaking as some recent announcements, but its effect is real. For developers building more demanding digital worlds, this tool becomes a quiet but powerful ally. It doesn’t impress with promises—it delivers results without drawing attention.
