Sakura School Simulator Lag Fix: Official Tips From Garusoft

Highlights

Garusoft recommends over 3GB RAM and over Snapdragon 820 for smooth play.
Below that, the developer warns of lag, shutdowns and low memory errors.
The official fix: restart the game or device and turn on "decrease students and people".
Close other apps, because the game uses a lot of CPU and GPU.
The 500m and 700m view distance from 1.048.18 is for high-spec devices only and uses more battery.

Sakura School Simulator looks simple, but it fills a whole town with students, teachers, cars and shops. On older phones that often means stutter, crashes or a frozen loading screen.

The developer, Garusoft, addresses this directly at the top of the game's Google Play page. This guide collects those official instructions, plus the settings added in recent updates.

Quick answer: To fix lag in Sakura School Simulator, Garusoft says to restart the game or device, enable "decrease students and people" in the settings and close other apps. Smooth play needs more than 3GB of RAM and a chip above Snapdragon 820. Keep the view distance at its default, because the 500m and 700m options are for high-spec devices.

Garusoft's Recommended Specs

Under "CAUTIONS" on the Play Store page, Garusoft lists the recommended environment for smooth play: over 3GB of RAM and a processor above Snapdragon 820. The developer is blunt: if your device is below this, the game "doesn't work smoothly", and becoming laggy, shutting down and low memory problems will occur soon.

Item	Garusoft recommendation
RAM	Over 3GB
Processor	Over Snapdragon 820
Background apps	Close as many as you can
If lag starts right away	Restart the game or device; enable "decrease students and people"

The Official Fix, Step by Step

Restart the game. If lag or crashes return soon after starting, restart the whole device.
Open the game settings and turn on "decrease students and people". Fewer NPCs means less work for the CPU and GPU.
Close other applications. Garusoft notes the game "uses a lot of CPU and GPU".

View Distance and the Sun: Settings to Leave Alone

Version 1.048.18 added a "Sun" option under Weather in Game Setting and longer view distances. According to the update notes, the 500m and 700m view distance can only be set on high-spec devices, and battery usage will increase.

If your phone is close to the minimum, leave view distance at its default. Longer distances draw more of the town at once, which is exactly what triggers lag on mid-range phones.

Heavy Scenes That Cause Lag

Lag is worst when many objects are on screen at once: crowded areas, many placed props and long chases. Practical habits that follow Garusoft's advice:

Keep scenes built with props small, especially before recording video.
Avoid stacking extra effects, such as long view distance, during busy scenes.
Save often with the SAVE button, so a crash does not cost progress.
Keep your phone cool and charged, since heat throttles the processor.

Still Lagging?

If the game still stutters after these steps, your device is probably below the recommended specs. On Android, check that the game is updated to the latest version, since recent releases like 1.048.19 fix specific display bugs.

FAQ (Frequently Asked Questions)

1. Why is Sakura School Simulator so laggy?

The game uses a lot of CPU and GPU. Garusoft says devices below 3GB of RAM and a Snapdragon 820-class chip will lag, shut down or run out of memory.

2. What does "decrease students and people" do?

It reduces the number of NPCs in the town, which lowers the load on your phone. Garusoft lists it as an effective fix for lag.

3. How much RAM does Sakura School Simulator need?

Garusoft recommends more than 3GB of RAM for smooth play.

4. Does view distance affect lag?

Yes. Since 1.048.18, 500m and 700m view distance are available only on high-spec devices and increase battery use.

5. Why does Sakura School Simulator close by itself?

On low-spec devices, Garusoft warns that shutdowns and low memory problems will occur. Restart the device, close other apps and enable "decrease students and people".
