The reason for this problem is:
1. The network environment is poor. You can confirm whether this problem exists through other machines in the same network.
2. The machine configuration is low. Confirm the hardware requirements of the game through official website or Baidu of the game, and select the recommended configuration reference. If the performance of the machine is low, please turn down the game special effects or upgrade the hardware (upgrading the notebook hardware mainly includes installing the memory and upgrading the solid state drive).
3. Games are not compatible-some games may not support certain versions of windows system well enough and have poor compatibility. At this point, you can set the compatibility mode.
