I know stretched res is common in CS/Fortnite, but I barely see COD or Warzone players talk about it seriously.
I tested native 1440p vs 1720×1080 stretched using the built-in COD benchmark instead of random gameplay clips, and the difference was bigger than I expected.
Not saying it is magic, and it obviously does not change hitboxes. The image is softer, but the GPU is rendering fewer pixels, so if you are GPU-bound it can actually matter.
I put together a walkthrough with the benchmark result, setup, and how to reverse it if it feels worse.
Curious what people here think: anyone actually running stretched in COD/Warzone, or is native still the move?
