Role	Required	Description
Unity Developer		Optimizes Unity XR applications for stable framerate: occlusion culling, LOD, draw call batching. Understands VR performance requirements: 72/90/120 FPS. Uses Unity Profiler for XR scenes.
Unreal Engine Developer		Optimizes Unreal XR applications: instanced stereo rendering, Fixed Foveated Rendering, draw call reduction. Understands VR framerate requirements (72/90/120 Hz). Uses stat commands.

Role	Required	Description
Unity Developer		Applies advanced XR optimizations in Unity: single-pass instanced rendering, foveated rendering, fixed foveated rendering. Optimizes for mobile VR: GPU skinning, texture atlasing, shader complexity reduction.
Unreal Engine Developer		Applies advanced XR optimizations in Unreal: VR forward renderer, mobile multi-view, dynamic resolution, Vulkan optimizations for Quest. Profiles via OVR Metrics Tool and RenderDoc.

Role	Required	Description
Unity Developer		Designs XR performance architecture for Unity: adaptive quality system, dynamic resolution, GPU/CPU load balancing. Develops custom profiling tools for XR-specific metrics (frame timing, reprojection).
Unreal Engine Developer		Designs XR performance architecture for AAA Unreal VR: adaptive quality framework, GPU/CPU budget management, platform-specific rendering paths. Develops custom profiling tools.

Role	Required	Description
Unity Developer		Defines XR performance standards for Unity studio. Establishes performance budgets for VR/AR platforms. Coordinates optimization efforts between graphics, gameplay and system programmers.
Unreal Engine Developer		Defines XR performance standards for the Unreal studio. Establishes per-platform budgets. Coordinates optimization across graphics, gameplay, and platform teams.

Role	Required	Description
Unity Developer		Defines XR performance strategy at studio level. Evaluates new optimization technologies (dynamic foveated rendering, neural super sampling). Shapes XR rendering roadmap.
Unreal Engine Developer		Defines XR performance strategy at studio level. Evaluates dynamic foveated rendering, Application SpaceWarp, neural upscaling. Shapes XR rendering roadmap.
