Following our testing of the FSR 2.1 implementation in Resident Evil 4 Remake, the loyal modding community continues to improve games before developers even release their patches. Several days after the release, PureDark and Praydog from the modding community introduce another important in-game improvement—NVIDIA's Deep Learning Anti-Aliasing (DLAA), NVIDIA's DLSS Super Resolution (DLSS 3.1) and Intel's Xe Super Sampling (XeSS) support in their ReFramework tool, which doesn't require any external software for installation. In order to run this game at maximum graphics settings and reasonable framerates at native resolution, quite a powerful GPU is required, which is why upscaling solutions are so important. But depending on the game, there are subtle differences in the implementation of NVIDIA's DLSS Super Resolution (DLSS 3.1), Intel's Xe Super Sampling (XeSS) and AMD's FidelityFX Super Resolution 2.1 (FSR 2.1), so we are keen to have a look at these temporal upscalers in this game.
How to install the NVIDIA's DLSS Super Resolution and Intel's Xe Super Sampling Mod for Resident Evil 4 Remake:
Extract the dinput8.dll file from the RE4 archive, the PDPerfPlugin.dll file from the UpscalerBasePlugin archive and the nvngx_dlss.dll file or all files from the XeSS archive in the Resident Evil 4 directory next to the main re4.exe file.
When using DLSS, you might need to adjust the LOD Bias values: using Nvidia Profile Inspector, set "Antialiasing Transparency Supersampling" to "0x00000008 AA_MODE_REPLAY_MODE_ALL" and "Texture Filtering LOD Bias (DX)" to -0.5000 for DLSS Quality mode, -1.0000 for DLSS Balanced mode, -1.5000 for DLSS Performance mode.
Launch the game, the REFramework window should appear, head to the Temporal Upscaler option and choose DLSS or XeSS.
Play the game with DLSS or XeSS (make sure you have disabled FSR 1.0/2.1 in your settings to avoid conflicts).
Below, you will find comparison screenshots at 4K, 1440p, 1080p, and in different DLSS, XeSS and FSR 2.1 quality modes; the Interlaced, TAA and DLAA screenshots are also available in the dropdown menu. For those who want to see how DLSS and FSR 2.1 perform in motion, watch our side-by-side comparison video. The video can help uncover issues like shimmering or temporal instability, which are not visible in the screenshots.
All tests were made using a GeForce RTX 3060 GPU at Maximum graphics settings with ray tracing enabled; motion blur and depth of field were disabled for better image viewing. In our testing we used DLSS version 3.1.11.
