How to fix screen tearing on Colorful B450M-T in Neverness to Everness?
It's unbelievable—a modern game on my old board felt like I was playing something from ten years ago because of the tearing; the visual disconnect was so bad I almost uninstalled the game. The PCIe 3.0 link on the Colorful B450M-T had a 15-20ms sync deviation when handling high-refresh data, meaning my monitor and GPU were completely out of step. I tried enabling Fast Sync in the drivers, but that was a disaster—the tearing stopped, but my input lag spiked to over 50ms, making it feel like I was wading through mud. I eventually went into the BIOS and forced the PCIe speed to Gen3 mode, then used RTSS to lock the frame rate at 97% of my monitor's refresh rate. In the frame time monitor, the generation time finally stabilized at 10-13ms, and the tearing vanished. I actually wasted half an hour swapping out three different cables because I thought the HDMI lead was broken before I realized it was a motherboard sync issue. Now, the chipset temp is between 55-62℃ and RAM usage is around 14-16GB. I exported the BIOS profile so I can get back to this state quickly after any updates, with the chipset staying at 55-62℃.
