Call of Duty: Warzone, the Modern Warfare campaign, and Black Ops War Zombies are finally receiving NVIDIA DLSS support. This means that owners of RTX 2000 and RTX 3000 cards should see up to 70% increased fps in all resolutions.
Based on the graphs from NVIDIA though, the 70% boost are only noticeable in 4K. It is because NVIDIA used different DLSS presets depending on resolution. NVIDIA chose Performance Mode DLSS for 4K, while 1440p and 1080p got Quality mode. The test system included an i9-10900K processor with 32GB of RAM with Maxed out video settings.
The RTX 3000 cards push more than 130 fps in 1080p but in 1440p, you’ll need an RTX 3060 Ti or higher to deliver more than 130 fps. At 4K, you’ll need an RTX 3080/3090 to get more than 130 fps.
