I'm getting severe screen tearing during high-speed mech flights in Titanfall on my Soyo H510M. Can PCIe settings fix this?

It's unbelievable that a fast-paced game looks like a slideshow of torn images on this board; the visual split was so bad I almost uninstalled. The PCIe link on the Soyo H510M had a sync deviation of 18-25ms when handling 144Hz data, meaning the GPU and monitor were totally out of sync. I first tried 'Fast Sync' in the drivers, but while the tearing stopped, my input lag spiked over 70ms—it felt like walking through mud, which was a disaster. I finally went into the BIOS, forced the PCIe speed to Gen3, and used RTSS to lock the frame rate at 141 FPS to match the monitor's refresh cycle. The frame generation time finally stabilized at 7-11ms and the tearing vanished. I actually wasted half an hour swapping three different cables thinking the wire was broken before I realized it was a motherboard sync issue. Chipset temps are 52-58℃ and RAM usage is 13-15GB. I saved the BIOS profile so I don't have to do this again. Controls feel snappy now.
