Investigate rendering quality of OutrunXR

When running the OutrunXR demo the rendering quality was perceived as jagged/pixelated. This could be seen with both models in the VR scene and the embedded 3D scene (View3D). There might be different aspects in play here, from rendering quality being dynamically decreased due to low frame rate to resolution of the assets being to dense. This task is about determining the exact reason to the visuals problems observed in the demo.
