How to fix horizontal tearing on VastArmor RX 9070 XT in Fortnite?
It's honestly ridiculous that I'm seeing jagged screen tearing on hardware this high-end. It made sniping feel like I was playing a slideshow. I checked the logs and the VastArmor RX 9070 XT Super Alloy Pro output frequency was bouncing between 200-300 Hz, completely out of sync with my monitor. I tried turning on V-Sync in-game, but the input lag spiked to 60ms—it felt like I was walking through mud, which is just a joke. I ended up going into the driver, maxing out Enhanced Sync, and capping the frame rate at 165 FPS. The frame time analyzer finally showed a stable 4-7ms window, and the tearing vanished. I did have some slight flickering after the first cap, but switching the sampling rate from 'Auto' to 'Manual' killed that. Core temps are now 60-66℃ with fans around 1400 RPM. I exported the performance logs to archive the sync data, and fan speeds are holding steady at 1400-1600 RPM.
