Vulkan is changing the landscape of graphics, ushering in a new age of visual fidelity for Android devices. While powerful, the API can be complex, as there are many ways of doing the same thing.

Therefore, Arm created a powerful set of samples to showcase the best practice of getting the maximum CPU and GPU performance on mobile.

In this in-depth talk, Arm and Roblox will dive into these best practices, comparing the performance impact of more than 10 sample code choices. It will also look at how the Roblox utilized the best practices to target better performance on Android.
