Both AMD and Nvidia have upgraded technologies that usually allow higher resolution images with lower quality rendering. In the Nvidia corner, you have Deep Learning Super Sampling, or DLSS, which has been around for several years. This is a rather complicated and resource-poor process, but this is an important reason why we see more and more real-time ray tracing in games.
AMD’s solution is called AMD FidelityFX Super Resolution (FSR), which is a very different approach. FSR is not intensive computer processing, but open source software, which uses special algorithms to enlarge images and give them sharper edges. When it first appeared, we tested it extensively. It is much simpler than DLSS, and although it has shortcomings, this simplicity also means that it can run on a wider range of GPUs.
Due to the long release time, it is not surprising that Nvidia has provided DLSS plugins for Unreal Engine 4 and 5 for some time. FSR took longer, but it can now be used as a plug-in for Unreal Engine 4.
be found Graphics card, FSR’s UE4 plug-in can be used by anyone from GPUOpen website. The website also outlines some useful information, such as recommended settings and descriptions of various modes. It also covers things to note, one of which is that FSR has integrated the contrast adaptive sharpening channel, so developers may need to disable any other channels.
It is great to see such software available to more people, especially when FSR is relatively lightweight. All kinds of developers can use it, and they don’t need the most powerful toolkit in the world to do this. Hopefully we can see FSR also enter UE5 soon.
