How to Fix Screen Tearing on a B850 Motherboard in South Africa

Screen tearing on a B850 motherboard setup is a timing mismatch between the frames your system renders and the moment the monitor refreshes, not a sign of a broken part. South African gamers usually see torn frames right after a hardware change because variable refresh, V-Sync or a frame cap reset at the same time. The fix is to get the GPU, the monitor and the game agreeing on timing again.

Quick Answer

Stop tearing on a B850 motherboard setup by enabling AMD FreeSync in the GPU control panel, switching the monitor on with VRR active, and capping the game a few frames below the refresh rate. For a 144Hz panel, cap around 141fps; for 240Hz, cap near 237fps, and leave V-Sync on as a backstop inside the VRR window. That combination removes tearing without adding the input lag that plain V-Sync introduces.

The order that removes tearing for good

1. Confirm the monitor's VRR feature is switched on in its own menu; many SA panels ship with FreeSync or G-Sync disabled. 2. Enable AMD FreeSync in the GPU control panel and tick it for both full-screen and windowed modes. 3. Set a global frame cap a few frames under the refresh ceiling so frames stay inside the VRR range. 4. Turn V-Sync on in the driver (not the game) as a backstop, which adds almost no lag while VRR is active. Test one game at a time, because a borderless-window title can behave differently from a true full-screen one.

FreeSync, refresh and frame caps on a B850 build in SA

On a B850 build, enable FreeSync in both the monitor menu and AMD Adrenalin, confirm the panel runs at its full refresh in Windows, then cap frames a few below the ceiling. At 144Hz cap near 141fps; at 165Hz cap near 162fps. A certified DisplayPort cable matters for high-refresh panels, since an under-spec lead drops the refresh and reintroduces tearing.

FAQ

Why did tearing start after the B850 motherboard change?

A hardware swap commonly resets VRR, the frame cap or the display mode, so frames and refresh fall out of sync. Re-enabling AMD FreeSync and re-capping the frame rate restores the tear-free behaviour you had before.

Should I just turn V-Sync on to fix tearing?

Plain V-Sync removes tearing but adds noticeable input lag, which hurts in fast games. A VRR setup with V-Sync only as a backstop inside the refresh window is smoother and far more responsive.

What refresh rate should I cap frames at on a B850 build?

Cap a few frames below your monitor's refresh: about 141fps for 144Hz or 162fps for 165Hz. That keeps frames inside the FreeSync window so the B850 build stays tear-free.
