The scope of 3D games is increasing day by day with more quality and performance. However, this requires hardware support for the running Android platform. Old devices are not obsolete yet.

It becomes a serious problem when the same application runs on various devices. This becomes a challenge for developers to run the same application across devices.

There are many technical differences between 2D and 3D games in terms of rendering, processing, and assets. The developer should always use an optimized approach to create assets and write code. One more way of gaining performance is to port the games for different hardware systems for both 2D and 3D games.

We can see a revolutionary upgrade in hardware platforms since the last decade. Accordingly, the nature of games has also changed. However, the scope of 2D games is still there with a large set of possibilities.

There are many frameworks and engines available for developing 2D and 3D games. Support for multiple operating systems has also increased its value for both 2D and 3D games.

Improving performance is more of a logical task than a technical one. There are a few tools available to do the job, but it is the developer's decision to choose them. So, selecting the right tool for the right purpose is necessary, and there should be a different approach to making 2D and 3D games.

We have already discussed the rendering processes in both 2D and 3D development. We will further enhance rendering with the help of shaders in Android and try to explore various techniques of optimizing Android games later in this book.
