UE 5 - learn to implement multi-GPU

Development Getting Started & Setup
4

Hello there!

  • Added support for multi-GPU rendering (mGPU). SLI is required. To enable it, pass -MaxGPUCount=2 on the Unreal Editor command line and set r.PathTracing.MultiGPU=1, which can be toggled at runtime. (r.AllowMultiGPUInEditor=1 is no longer required in .ini files to enable mGPU in the editor.)
