Define what is shaking
Stand still, lower both hands, and turn your head slowly. If the entire scene jitters, focus on runtime, refresh rate, performance, or headset tracking. If only one paw jumps, test that controller. If the problem appears only during one interaction, use the objective guide instead.
Run the same check in the headset's system space or another stable VR application. If the shake exists outside I Am Cat, stop changing the game's graphics and troubleshoot tracking or the runtime. If it appears only inside this game, continue with the controlled checks below.
Apply updates before workarounds
Steam announcements document camera-jitter and performance fixes. Install the current build, restart SteamVR and the headset software, and begin from a clean launch before editing several settings.
Confirm the installed build actually changed after an update. Then close optional overlays and performance injectors for the first baseline run. They can be restored later, but leaving them active makes it harder to separate a game problem from an extra rendering layer.
Choose one runtime and refresh rate
Confirm which OpenXR runtime is active. Test one normal refresh-rate option supported by the headset, then repeat the same slow head turn in the same room. Avoid changing supersampling, refresh rate, runtime, and overlays together.
If a lower refresh-rate test is stable, do not immediately raise several graphics settings. Repeat the test once, note the result, and change only the next most likely variable. If no supported rate helps, return to the original setting so the next test starts from a known baseline.
- One active OpenXR runtime.
- One refresh-rate change.
- Same save and scene.
- Same movement test.
Record the result
Write down headset, runtime, refresh rate, GPU, game build, room, and whether the shake follows head or hand movement. That turns a vague complaint into a test another player can reproduce.
Stop the test if the shake causes discomfort. A short video recorded from the headset mirror can be useful, but it may not capture tracking judder exactly as it feels in the headset. Describe both the recording and the in-headset symptom instead of treating one as complete proof.
