@Nexus18 in Doom Eternal even with DLSS 3.7 and Preset E, DLSS Quality seems to show more issues than native as I mentioned before. It's likely due to the age of the engine and being in Vulkan.
1: Reflections off the gun barrel for example are lower fidelity using DLSS Quality
2: There is slightly more jaggedness using DLSS Quality than native
Other than that there's very little resolving difference between native and DLSS Quality in this game

Ignore the black level in the shadows in the top one, that was just Photoshop's export.
