Should I lock core clocks to fix RTX 5070 OC tearing in Destiny 2?
When sliding across the battlefield at high speeds, the fluidity was suddenly killed by a horizontal tear across the screen. It was actually exciting in a weird way because it pointed directly to a frequency scheduling flaw. The GDDR7 memory on the Manli Snow Fox RTX 5070 OC had a 2-4ms sync offset during high-speed switching, which knocked the render frames out of sync with my monitor. I tried turning on V-Sync, but the input lag jumped to over 40ms, making the controls feel like I was playing in mud. I used MSI Afterburner to lock the core clock at 2450MHz and disabled the auto-boost, then locked the refresh rate to 144Hz. The frame time analyzer showed the 6-15ms variance shrink to a tiny 6.8-7.2ms window, and the tearing vanished. I had a couple of driver resets when I first locked the clock, but a tiny voltage bump to 1.05V made it stable. The GPU stays at 58-64℃ with fans at 1300RPM. I verified with a frame comparison tool that the tearing is 100% gone, and fans now sit between 1400-1600RPM.
