How to stop signal drops on MSI MPG Z890 EDGE TI WIFI?

That horizontal tearing during stealth was absolutely killing the immersion for me. After digging into the hardware, I found that the PCIe 5.0 lanes on the MSI MPG Z890 EDGE TI WIFI were in 'Auto' mode, and signal interference was causing them to randomly drop to Gen 4, creating micro-interruptions in data flow to the GPU. My first instinct was to enable V-Sync in the driver, but that was a mistake—input lag spiked to 35ms, making the controls feel sluggish and heavy. I went back into the BIOS, manually locked the PCIe slot speed to Gen 4, and flashed the latest microcode update. Checking with a frame time analyzer, the intervals tightened from a jittery 18-30ms to a consistent 14-16ms, and the tearing completely disappeared. I almost bricked the board when a power outage hit during the BIOS flash, but I managed to save it using the Flash BIOS button. Chipset temps settled at 48-54℃, and memory stayed between 58-63℃. The image is finally clean.
