For stuttering, start with reversible, free checks—reduce demanding graphics settings, close background apps, confirm the game is using the right GPU, and check for heat—before reinstalling drivers or considering hardware.
Tell network delay from frame-rate stutter
Watch what happens when the problem occurs. If the game looks smooth but your character or an online action responds late, the issue may be network latency. If the camera or animation visibly hitches, freezes briefly, or runs unevenly, suspect rendering or PC performance instead. A graphics tweak is unlikely to solve an online-only delay; check your connection separately. The official support guidance cited here focuses on game performance and does not provide a universal network diagnostic.
Note whether the hitch happens during camera movement or effects-heavy scenes, began after a game update, or gets worse as the computer warms up. These clues help you choose what to check first.
Try low-risk performance checks first
Change one thing at a time, then replay the same area or activity. That makes it easier to tell whether a change helped. Menu names and available options differ by game and version.

Reduce graphics load
Lower the resolution and demanding settings such as shadows, texture quality, and visual effects. HoYoverse recommends reducing graphics quality for Genshin Impact stuttering and frame-rate drops, and identifies resolution, shadows, and texture quality as settings to adjust. You can also try V-Sync if you see tearing or uneven frame pacing; compare how responsive the controls feel, since the result varies by setup. HoYoverse’s stuttering and frame-rate guidance covers these checks.
Close apps competing for resources
Close applications you do not need while playing, particularly resource-heavy browsers or streaming software. HoYoverse recommends closing unnecessary background apps in its Genshin Impact troubleshooting guidance.

Make sure a laptop uses its discrete GPU
If your laptop has both integrated and discrete graphics, check that the game is assigned to the high-performance GPU. Using integrated graphics unintentionally can limit performance. HoYoverse’s Genshin Impact PC FAQ describes selecting a discrete GPU for certain PC problems; the exact setting path depends on your system.
Check for heat and airflow problems
If performance worsens as the laptop or PC heats up, make sure vents are not blocked, the computer has room to breathe, and fans are clean. Monitor component temperatures while playing and note whether the slowdown tracks with rising heat. The cited guidance does not establish a universal safe temperature threshold, so do not treat one number as a diagnosis.

A laptop cooling pad is an optional consideration only if you have identified a heat or airflow problem. HoYoverse advises ventilation and temperature monitoring; that does not establish that a cooling pad will fix stuttering.
Verify game files and update graphics drivers
If settings and background load do not explain the problem, check the game’s files and the graphics driver. Use the game launcher’s resource integrity or re-verification feature when available. For Genshin Impact, HoYoverse recommends checking resource integrity; Honkai: Star Rail support recommends re-verifying downloaded resources. The precise labels can vary by launcher version.

Get graphics drivers from the official website for your GPU maker—NVIDIA, AMD, or Intel. If a normal update does not help, a clean driver installation is a later step HoYoverse recommends for persistent issues. Check the instructions for your GPU and operating system before removing or reinstalling a driver.
For a specific low-end PC issue, HoYoverse suggests medium Global Illumination and Character Dynamic High Precision alongside driver steps. Those settings address the situation described in that support article; they are not universal recommendations for every gacha RPG or PC. See HoYoverse’s low-end PC guidance.

Use game-specific support steps where they apply
- Genshin Impact: Check that the PC meets the game’s requirements, lower graphics quality, close background applications, verify resource integrity, and update or clean-install graphics drivers. If support asks you to wait before restarting, follow that instruction. The system requirements in the older PC FAQ should not be treated as current hardware-buying advice.
- Honkai: Star Rail: If the game crashes or freezes, re-verify downloaded resources, update or clean-install the GPU driver, and check the game’s minimum requirements. See HoYoverse’s Honkai: Star Rail troubleshooting steps.
Escalate with details support can use
If the problem remains, collect evidence before contacting the game’s support team. Record your CPU, GPU, RAM, and device model; capture a screenshot or short video of the hitch; and note the exact time it happened. Include requested diagnostic reports and logs. HoYoverse guidance mentions DxDiag for stuttering reports and, for Genshin PC support, output logs, crash dumps, and a driver error log. Some logs may reset after restarting, so retrieve them while the issue is occurring if support instructions ask you to.
When to consider a hardware change
Do not buy a GPU, laptop, or cooling accessory just because a game stutters. First identify the symptom and check graphics load, background resource use, GPU selection, game files, drivers, and heat. Consider hardware only after those checks point to a specific limitation; the cited support material does not establish an FPS target, temperature cutoff, expected performance gain, or hardware shortlist.
