想做遊戲但不知從哪開始，Unity能幫你什麼

What's new in this version:

Features:
- Mobile: Adaptive view distance scaler - A new scaler to change the Camera.main view distance automatically
- Mobile: Boost mode - Boost CPU and GPU for short periods of time
- Mobile: Cluster info - Request cluster info to have details which and how many cores are available on the device
- Mobile: Feature API - Check which Adaptive Performance feature is available on the current platform
- Mobile: Scaler profiles - Easily define and change Adaptive Performance Scalers with predefined profiles

API Changes:
- Graphics: Added: Added SpeedTree8MaterialUpgrader, which provides utilities for upgrading and importing SpeedTree 8 assets to scriptable render pipelines
- HDRP: Added: Added SpeedTree8MaterialUpgrader, which provides utilities for upgrading and importing SpeedTree 8 assets to scriptable render pipelines
- Shadergraph: Added: Added an HLSL file implementing a version of the Unity core LODDitheringTransition function which can be used in a Shader Graph
- Shadergraph: Added: Added subshadergraphs for SpeedTree 8 shadergraph support: SpeedTree8Wind, SpeedTree8ColorAlpha, SpeedTree8Billboard
- URP: Added: Added a SpeedTree 8 Shader Graph but did not set it as the default when importing or upgrading Speed Tree 8 assets. Because URP doesn't yet support per-material culling, this Shader Graph does not yet behave in the same way as the existing handwritten SpeedTree 8 shader for URP.
