There’s nothing more frustrating than gearing up for a tough Memory of Chaos fight, loading into the stage, and hitting a massive lag spike right as your main DPS uses their ultimate. I’ve lost so many 5-star clear runs to random stutters, frame drops, and 2-minute loading screens across my old mobile, mid-tier laptop, and even my relatively new desktop. After testing dozens of setting combinations, background tweaks, and hardware fixes over 6 months of playing, I’ve figured out how to make Honkai Star Rail run smoother on almost any device, no expensive upgrades required. These tips work for both low-end budget hardware and high-end gaming rigs, so you can stop wasting time troubleshooting and get back to pulling for your favorite characters.
How to make honkai star rail run smoother on mobile: optimized in-app settings first
Mobile players deal with the most frequent lag issues, since most people play on mid-range or older devices that weren’t built for high-intensity 3D games. The good news is that 80% of mobile lag can be fixed with simple in-app setting adjustments, no extra tools required. You don’t have to crank all settings to max to enjoy HSR’s combat and story, even low settings keep all core visual details intact. I tested these tweaks on my 3-year-old iPhone 12 and my cousin’s budget Redmi Note 11, and both devices saw a 30-40% frame rate boost after making the changes.
Start with these priority setting adjustments first, testing after each change to see what works best for your device:
- Drop render resolution to 0.8x or lower if you’re using a budget device: this cuts GPU load by almost 30% with barely noticeable visual downgrades
- Turn off anti-aliasing entirely if you’re experiencing constant frame drops: TAA and FXAA both use significant processing power that most mid-range mobile chips don’t have to spare
- Disable post-processing effects like bloom, motion blur, and ambient occlusion: these add visual flair but do almost nothing to impact actual gameplay, so cutting them will give you an instant frame rate boost
- Set frame rate cap to 30fps instead of 60 if you’re dealing with overheating or random shutdowns: a consistent 30fps is far better than a choppy 60fps that drops to 10 during combat
Once you adjust in-app settings, close all background apps you’re not using, especially streaming apps or social media apps that run constant background updates. Never use your device’s built-in battery saver mode while playing HSR, as it intentionally cuts processing power to extend battery life and will make lag far worse. If you play for more than 2 hours at a time, invest in a cheap $10 mobile cooling fan to prevent overheating throttling, which is one of the most common causes of random frame drops on mobile.
PC optimization tweaks for consistent, high frame rates
PC players often assume their high-end rigs will run HSR perfectly, but I’ve seen even $2000 gaming desktops struggle with random stutters because of simple system setting misconfigurations. Most PC lag issues have nothing to do with your hardware, and everything to do with background processes hogging resources or outdated software.
First, update your GPU drivers before you touch any in-game settings. I once had a 20fps drop right after the Penacony update, and I spent an hour adjusting in-game settings before I realized I hadn’t updated my Nvidia drivers in 2 months. Updating took 10 minutes and fixed the frame drop entirely. Next, adjust your in-game settings based on your GPU: if you have a GPU older than 3 years, turn off ray tracing entirely, it’s not worth the 40% frame drop for slightly better light reflections that you’ll barely notice during fast combat.
For Windows users, set Honkai Star Rail’s priority to High in Task Manager to make sure your system allocates more processing power to the game over background apps. You can do this by opening Task Manager, going to the Details tab, finding StarRail.exe, right-clicking it, and selecting Set Priority > High. You have to do this every time you launch the game, but it’s 10 seconds of work for a 15-20% frame boost. If you’re playing on a laptop, make sure it’s plugged in and set to Performance power mode, not Balanced or Power Saver. I forgot to plug my laptop in once during a Simulated Universe run and couldn’t figure out why it was lagging so bad until I saw the battery at 20%.
Fix common lag causes that most players miss
Even if you have perfect in-app and system settings, there are a few overlooked issues that can cause constant lag and stutters for all device types. These are the first things I check when someone tells me they’re still having lag after adjusting all their settings.
First, check your available storage space. HSR needs at least 20GB of free space on your drive to run properly, because it constantly loads and unloads temporary files as you move between areas. If your storage is more than 90% full, your device can’t write these temporary files quickly, leading to long loading times and in-game stutters. If your internal storage is more than 90% full, move HSR to an external SSD or delete unused files to free up space immediately. I freed up 30GB on my old Android phone once and cut loading times for new zones in half, no other changes required.
Next, check your internet connection. A lot of lag people assume is device performance is actually bad internet, especially in co-op or when loading new areas that pull assets from the server. If you’re on Wi-Fi, move closer to your router, or switch to a 5GHz connection instead of 2.4GHz for faster speeds and less interference. PC players should use a wired Ethernet connection if possible, it cuts down on ping spikes by 70% in most cases. You should also clear your game cache every 2-3 months, especially after big version updates. Old cache files get corrupted over time and cause random stutters, and clearing it only takes a couple of minutes from the game’s launch screen.
When to upgrade hardware for better HSR performance
Sometimes all the setting tweaks in the world won’t fix your lag, especially if you’re using very old hardware that doesn’t meet the game’s minimum requirements. You don’t have to spend a fortune on new hardware though, HSR is surprisingly well optimized for mid-tier devices if you know what to look for.
For mobile players, if your phone is older than 4 years and you still get under 25fps in combat with all settings on low, it’s probably time for an upgrade. You don’t need a $1000 flagship phone either. For Android, any device with a Snapdragon 7+ Gen 2 or higher chip will run HSR at 60fps on medium settings easily, and you can find these phones for under $400. For iPhone, any iPhone 13 or newer will run the game perfectly with no issues, even at max settings.
For PC players, the biggest upgrade you can make for HSR is switching from an HDD to an SSD. If you’re running the game on a traditional hard drive, you’ll have 2-3x longer loading times and constant stutters when moving between areas, even with a high-end GPU. You can buy a 1TB SSD for under $50 right now, and it will make a bigger difference than any other upgrade for general game performance. You don’t need a top-tier $2000 gaming PC to run HSR well: a $500 mid-tier build with an RX 6600 GPU will run the game at 1080p 60fps on max settings with no lag. Only upgrade your GPU if you’re still getting under 30fps on low settings with an SSD and no background processes running.
At the end of the day, you don’t need a top-of-the-line device to enjoy everything Honkai Star Rail has to offer. Most of the fixes that help you reduce lag and boost frame rates are completely free, and take less than 10 minutes to apply. I’ve used every single tip in this guide on at least 3 different devices, and they’ve all helped me cut loading times in half and eliminate random combat stutters entirely. If you’ve been struggling with lag, start with the in-app setting tweaks first, then move to system-level fixes before you consider spending money on new hardware. Taking 10 minutes to adjust these settings will help you make Honkai Star Rail run smoother, so you can focus on what matters most: enjoying the story, clearing endgame content, and pulling for your dream 5-star characters.
