For your reference, the reasons for lagging are listed below:
1. Intensive gaming can cause the device to heat up, triggering thermal throttling where the system reduces performance to cool down, resulting in lag;
2. High graphics settings or advanced features within the game will be too demanding for the tablet’s hardware, causing lag;
3. Insufficient memory can cause the Redmi Pad SE 8.7 4G to lag. It's recommended to clear background APPs immediately if you experience lag.
Note:
1. It is not recommended to play large, resource-intensive games when the tablet is in a high-temperature state;
2. It is advised to close unnecessary background applications and perform regular memory clean-ups when playing heavy games.
