Why does Overwatch 2 feel stuttery even when the FPS counter looks fine?

Overwatch 2 can show a decent FPS counter while still feeling weirdly choppy. The usual pattern is smooth movement for a bit, then short spikes when the camera turns or a busy area loads.

What is the cleanest way to test whether this is a shader, CPU, VRAM, or overlay problem? The setup points worth checking here are render scale, Reflex, voice devices, and packet-loss indicators. I’m looking for a fix order that does not start with reinstalling the whole game.

Start with a controlled frame-time test instead of dropping every preset.

1. Disable third-party overlays and recording tools for one run.
2. Use exclusive fullscreen if Overwatch 2 supports it; otherwise test borderless with Windows fullscreen optimizations both on and off.
3. Set a frame cap a few FPS below the refresh-rate limit or below the FPS the PC can hold consistently.
4. Clear only the Windows DirectX shader cache after a driver change, then let the first launch finish rebuilding.
5. Watch GPU usage, VRAM use, and one or two busy CPU cores. High GPU use points to graphics load; low GPU use with one maxed core points to CPU or simulation load.
6. Reduce textures only when VRAM is close to full. Reduce crowd, view-distance, physics, or simulation settings when the CPU is the limit.

For Overwatch 2, pay special attention to render scale, Reflex, voice devices, and packet-loss indicators. Change one item at a time and retest the same location. A stable cap usually feels better than a higher average with constant spikes.
