Open Phone Menu > Settings > Graphics and start with Graphics Quality set to Low, Full Screen at the monitor's native resolution, and 60 FPS only if the PC can hold it. Reduce Rendering Quality, Shadow Quality, Reflection Quality, and Special Effects one step at a time while repeating the same battle or map route. Use 30 FPS when 60 repeatedly drops; do not edit the Windows registry to force a higher limit.
Stand at the start of a short route or battle that regularly stutters. Turn the camera through the same view and use the same attacks for every test. Note the usual FPS if you already use a trusted counter; otherwise watch the same animation for pauses and uneven movement.
2
Apply the Low graphics preset
Open Phone Menu > Settings > Graphics and set Graphics Quality to Low. Use Full Screen and the monitor's native resolution for the first run, apply the settings, and repeat the test. This establishes a low-load result before you tune individual options.
3
Set an FPS target the PC can maintain
Set FPS to 60 only if the test stays close to 60 during combat and camera movement. If it repeatedly falls well below that target, choose 30 FPS and repeat the same test. Use only the frame-rate choices shown in Star Rail's Graphics menu; do not edit GraphicsSettings_Model in Registry Editor.
4
Lower the controls that affect the scene
If Low still stutters, reduce Rendering Quality one step, then test. Next lower Shadow Quality, Reflection Quality, and Special Effects Quality one at a time. Keep Character Quality and Texture Quality higher only if the PC has enough graphics memory and the repeated test stays stable.
5
Compare V-Sync instead of guessing
Turn V-Sync on and repeat the same camera turn. Keep it on if tearing disappears and movement is steadier. If it adds an unwanted delay or does not help the visible problem, restore the previous value; do not change the FPS target during this comparison.
6
Check heat and the active graphics driver
Run the test for five minutes. If performance starts well and then falls, clear blocked vents and let the laptop cool before testing again. In Windows, open Task Manager > Performance to identify the active GPU, then install its current driver from NVIDIA, AMD, or Intel if it is outdated.
7
Keep the highest stable profile
Success means the same route or battle stays smooth for five minutes at the chosen FPS limit without overheating or crashing. Raise one visual option at a time only after that result is stable. If Low at 30 FPS still stutters, compare the PC with HoYoverse's minimum requirements and send Support a settings screenshot, DxDiag report, and hardware details.
If it does not work
If Star Rail becomes blurry after lowering Rendering Quality, restore that one control and reduce shadows, reflections, or special effects instead.
If the laptop is smooth on mains power but slow on battery, reconnect its charger and repeat the same test. Results from different power states are not comparable.
If the picture is smooth but actions respond late or characters jump, check the in-game ping and use the login/network guide; graphics settings do not repair network delay.
If changing the preset causes a crash, use the login-screen Update control > Re-verify the integrity of the downloaded resources, then restore Low before testing again.

Checked against official documentation on . Scope: Honkai: Star Rail on Windows PC.
The preset is a low-load starting point, not a promised universal optimum. HoYoverse's current guidance supports lowering graphics, testing V-Sync, updating the active GPU driver, and checking minimum requirements.
