Everything has gone blurry for me and my friend after about 50 hours on calamity + some other mods. its only blurry in motion and sharpens up when still, we both noticed when we logged on one day. we are both running 40 series cards and 14th gen intel cpus, 144hz monitors. i feel like ive messed with every nvidia setting under the sun and still nothing, no changes, ive also tried every in game and mod setting that i could, still nothing. after about 500 hours total im at a loss ive never seen this happen.
