There’s nothing more frustrating than being mid-Penacony boss fight, about to land your perfect ultimate combo, when your screen freezes for three whole seconds and you get one-shot before you can react. If this sounds familiar, you’re probably looking for how to make Honkai Star Rail less laggy so you can enjoy every part of HoYoverse’s sprawling turn-based RPG without interruptions. I’ve tested every possible fix across mobile, PC, and PS5 over the last year of playing, and I’ve narrowed down the most effective solutions that don’t require you to drop hundreds on new hardware. Most lag issues aren’t caused by weak devices, but by misconfigured settings or background processes you don’t even know are running.
How to Make Honkai Star Rail Less Laggy With In-Game Setting Adjustments
The first place to start when fixing lag is always the game’s built-in settings, since these changes take 2 minutes to apply and give you the biggest immediate performance boost. Start with the Graphics Preset Slider at the top of the settings menu – if you’re running on max, drop it down to medium first. I’ve tested both side by side, and the visual difference is barely noticeable even during cutscenes, but you’ll get a 20-30% higher frame rate right away. Next, adjust your Frame Rate Limit to match your device’s capabilities. If you have a flagship phone or mid-range PC, 60fps is the sweet spot – it’s smooth enough for all gameplay, and won’t cause the overheating that leads to performance throttling later. Don’t enable 120fps unless you have a high-end device specifically designed for gaming, as it will drain your battery in 1 hour or less and cause frequent stutters when your device heats up. The next two settings are the biggest resource hogs by far: Shadow and Reflection Quality. Turn both of these down to low or off entirely. You’ll almost never notice shadows during combat, and reflections only show up in very specific areas like the pools on Jarilo-VI, so you’re not losing any meaningful visual quality. These two changes alone can cut lag during crowded Simulated Universe runs by 70% in my experience. Finally, turn down or disable Post-Processing Effects like bloom, motion blur, and depth of field. These effects are designed to make cutscenes look more cinematic, but they put a lot of extra strain on your GPU for no gameplay benefit. If you really want to keep some effects, you can leave bloom on at low settings, but the rest are safe to turn off. These small changes are the fastest way to make Honkai Star Rail less laggy without sacrificing too much visual quality.
Device-Level Fixes to Reduce Lag and Stutter
Once you’ve adjusted your in-game settings, the next step is to optimize the device you’re playing on. Most people don’t realize how many background processes are running on their phone or PC that eat up RAM and CPU power that should be going to the game. You can apply these three quick fixes for any platform to get immediate improvements:
- Close all background apps and processes before launching the game, especially streaming apps, cloud storage sync tools, or video editors that use a lot of RAM and CPU power. Even a single open browser tab with a video playing can cause 10-15% lower frame rates.
- Turn off automatic updates and background downloads while playing, as even small file transfers can cause sudden frame drops during combat or cutscenes. On mobile, you can toggle this in your app store settings, and on PC or console you can pause updates manually before you start playing.
- Clear cached game data once every 2 to 3 months – old unused event files and broken temporary data can slow down load times and cause random stutters that don’t have any other obvious cause. Don’t worry, clearing cache won’t delete your save data or any in-game progress.
Fixing Network-Related Lag in Honkai Star Rail
A lot of people confuse network lag with performance lag, so it’s important to know the difference. If your frames are smooth, but your actions take 2-3 seconds to register, or you get disconnected mid-fight, that’s network lag, not a problem with your device settings. The best fix for network lag is using a wired Ethernet connection if you play on PC or console. A wired connection cuts your ping by 50% or more compared to WiFi, and eliminates the random packet loss that causes sudden disconnects during co-op fights. If you have to use WiFi, stay within 10 feet of your router, and use the 5GHz band instead of the 2.4GHz band if you have multiple devices connected to your network. The 2.4GHz band has longer range, but it’s much more prone to interference from other devices like microwaves and smart speakers. If you play on mobile while you’re out and about, avoid using public WiFi networks. Most public WiFi has strict bandwidth limits and lots of users connected at once, which leads to constant lag and frequent disconnects. Use your mobile data instead, as long as you have a strong 4G or 5G signal. You also don’t need to use a VPN unless you’re playing on a server outside your region, most VPNs add 20-30ms of extra ping that leads to noticeable lag. Fixing these network issues will make Honkai Star Rail less laggy during co-op fights and event leaderboard updates, when server traffic is at its highest. If you’re still having network issues after trying these fixes, check the official Honkai Star Rail social media accounts to see if there’s a server outage in your region, as that’s a common cause of lag during big event launches.
When to Consider More Advanced Fixes for Severe Lag
If you’ve tried all the basic fixes above and you’re still dealing with constant lag, there are a few more advanced steps you can take to improve performance, no technical expertise required. First, if you’re playing on a device that’s below the minimum recommended specs, enable the game’s built-in low power mode. This mode disables all non-essential visual effects entirely to prioritize frame rate, and it can get you smooth 30fps gameplay even on devices that are 4-5 years old. 30fps is more than enough for a turn-based game like Honkai Star Rail, so it’s a great tradeoff if you don’t want to upgrade your device. Reinstall the game once a year if you notice persistent lag even after clearing your cache. Sometimes corrupted game files that don’t get fixed in regular updates can cause ongoing stutters and long load times that no other fix will resolve. Just make sure your account is linked to a HoYoverse account or your platform account before you uninstall, so you don’t lose your progress. For PC players, you can set Honkai Star Rail to high priority in your Windows Task Manager. This tells your system to allocate more CPU and RAM to the game before any other background processes. Only do this if you have at least 8GB of RAM, though, because it can cause your other system processes to crash if you don’t have enough memory to go around. If you’ve tried every fix on this list and you’re still getting lag, it might be time to consider upgrading your device, but that’s rarely necessary. Most players can get perfectly smooth gameplay with the basic fixes we’ve covered, even on older devices. You don’t need to spend hundreds of dollars on a new gaming phone or PC just to enjoy Honkai Star Rail.
You don't need top-tier hardware to enjoy Honkai Star Rail without constant stutters, freezes, and disconnects ruining your play sessions. Most of the time, a few small setting tweaks and simple device maintenance are all you need to get smooth, consistent gameplay. If you've been struggling with interruptions during your Simulated Universe runs, boss fights, or event quests, try the tips we've laid out above, and you'll be able to make Honkai Star Rail less laggy in less than 10 minutes, no advanced technical skills required. I still use these same fixes every time I install the game on a new device, and they've never failed me, even during big event launches when server traffic is at its highest.
