Solving Manli Snow Fox RTX 5080 OC tearing in Manor Lords
Whenever I zoomed out on the city map, I'd see these blatant horizontal breaks across the screen, making precise placement a total nightmare. The GDDR7 memory on the Manli Snow Fox RTX 5080 OC seemed to have occasional sync clock offsets during high-bandwidth bursts, causing the refresh rate to wobble between 138-144Hz. I first tried forcing Fullscreen Optimizations in the control panel, but that actually made the tearing worse and added some weird color fringing. I eventually went into the BIOS, disabled the onboard graphics, and forced the PCIe link to its maximum power state. Using RTSS, I saw frame times tighten from a shaky 6-12ms to a rock-steady 6.2-6.5ms. I noticed a huge spike in input lag when I first turned on V-Sync, but switching to Fast Sync solved that immediately. Core temps are now a chilly 55-62°C with very low fan noise. Tearing is completely gone, and fans are steady at 1100-1300RPM.
