Compare of the VR HMD 1:1, only native resolution without SS

Did anyone make Pimax5K/8K compare with other VR HMD but only on the native resolution without any Supersampling?
Somehow this will represent true compare because I notice Pimax need much more SS than competitive HMD’s even lens should suggesting should be less. This makes a question about PiTool efficiency so such test should answer this concerns. Should we worry or not?

Competitors bu default ss higher than native res of headsets.

Leaving Steam res on auto should do trick for compare.
