Fixing screen tearing in Starfield on Galax B760M D4 Wi-Fi White Phantom
It's unbelievable that a next-gen game looks like it's from 2010 on my rig. The visual tearing was so bad I almost uninstalled. The PCIe link on the Galax B760M had a 17-24ms sync offset during high-refresh data streams, meaning the GPU and monitor were totally out of step. I tried 'Fast Sync' in the drivers, but that pushed input lag to over 68ms—it felt like walking through mud, which is just unacceptable. I went into the BIOS and forced the PCIe slot to Gen4 mode, then used RTSS to lock the frame rate at 97% of my monitor's refresh rate. Frame times finally stabilized at 10-14ms, and the tearing vanished. I wasted a half hour swapping three different cables thinking the HDMI was dead before I realized it was a board sync issue. Chipset temps are 52-58℃ and RAM is at 14-16GB. I saved the BIOS profile so I don't have to do this again. Frame times are rock steady at 10-14ms.
