VR rendering is lighter than split-screen.
Most of render schene is the same... the addicitional rendering is the diferent view points.
Split-screen = two different renders.
VR = same render with different viewpoints
That is why it is not rendering 2x 2000x2040... it close to rendering 2000x2040... it shoudl be around 60-70% of the actual 2x 2000x2040.
With foveable rendering it is even lighter because it choose to rull render only the parts you are looking while the others are a more light render.
