Banuba Face AR SDK is already optimized out-of-the-box and performs well even on lower-end devices. But to further reduce RAM usage by your app, you can configure the render size.
find file 'EffectPlayerConfinguration' in BanubaSdk.xcodeproj/BanubaSdk/EffectPlayer/Configuration/EffectPlayerConfinguration.swift
Here you can change 'photoRenderSize' and 'videoRenderSize' parameters to optimize RAM usage.
