Performance issues when developing for VR/AR platforms can be managed by optimizing code, using efficient algorithms, and utilizing hardware resources.
For example, when developing a VR game, you can optimize code by writing code that is specific to the hardware and platform you are targeting. This will help reduce the amount of resources used and improve the performance of the game. You can also use efficient algorithms to reduce the amount of processing power needed to render the game. Finally, you can utilize the hardware resources available to you, such as GPU and CPU, to ensure that the game runs smoothly on the platform.
