Cloud game is widely popular as an emerging game mode. Cloud game is carried out on the cloud server through game calculation and rendering tasks, and players can complete the game experience as long as they accept the video stream and send control commands through the network. However, the fluidity and quality of the current cloud gaming experience can be affected by a number of factors.

The delay of network bandwidth can cause delays and other effects on cloud games. Cloud games on the network requirements are stable and high-speed, in order to ensure that the game picture is clear and real-time transmission. When there is insufficient network bandwidth, the video quality of cloud games may be reduced or stuck. Low latency is critical for cloud gaming, as high latency can cause significant delays between player actions and game responses, which can affect the gaming experience. Ideally, the delay should be kept within 20-30ms.

The performance of cloud servers hosting cloud games is also critical. Cloud server performance is affected by the configuration and load of the cloud server. The computing and rendering tasks of cloud games need to be completed by the cloud server, and the CPU and memory of the cloud server directly affect the fluency of the cloud server. A high-performance server can provide a better gaming experience. When the load on the cloud server is too high, there may be insufficient resource allocation, game performance degradation and stutters. Cloud games require cloud service providers to provide reasonable management and scheduling of server resources.

Client devices also affect cloud gaming usage. Most of the computing takes place in the cloud, but the client device still needs enough decoding power to process the incoming video stream. When the performance of the client device is insufficient, the video streaming is not smooth. Client device display resolution and refresh rate will also affect the game experience, high resolution and high comfort display can provide better visual effects, but the bandwidth consumption is also more, also requires device performance support.

The reason of video coding and decoding technology will also lead to the cloud game lag, the cloud game uses the video coding technology to compress the rendered game picture into a video stream, efficient coding technology can ensure the quality of the picture while reducing the bandwidth occupation. The client device needs to decode the received video stream in real time, and the decoding efficiency directly affects the fluency of the game. Hardware-accelerated decoding can improve decoding efficiency and reduce latency.

The cloud game server is generally deployed in the data center, the geographic location of the data center and the distance of the player will affect the network delay, and the closer data center will also provide a lower ability to eat, improve the cloud game experience. CDN can deploy cache nodes in multiple locations, reduce data transmission distance, optimize network performance and improve game fluency.

Network stability and interference affect the player experience of cloud gaming. Network fluctuations, packet loss, jitter, etc., can affect the smoothness of cloud gaming. The interference of wireless network environment will also affect the network quality.

There are many factors affecting whether the cloud game is stuck, among which the network aspect, cloud server performance, client equipment, video coding and decoding technology, data center location and network stability have a greater impact. To ensure the cloud game experience, you are advised to use high bandwidth, low latency, stable network connections, and good client devices. Cloud server providers must provide high-performance cloud servers and optimized network architectures.
