Thx @faizalski
For someone who is familiar with Quest3 , the Quest3S feels a little bit of a downgrade. The Fresnel lens of Q3S brings back the glary visuals as it was in the days of Q2 with its concentrated rings, only observable in dark scenery with white subjects though.
However the plus side would be the performance to price ratio, it perform exactly like the Q3 , all those heavy content like 6dof that i tested perform exactly like what i would expect from Q3.
Passthrough quality of Q3 is better then Q3S though, the Q3S somehow have a slight yellowish tint to the passthrough for whitish subject being displayed. Still ,by no means this diminish the mix reality capability of Q3S. I think Q3S stands a chance to be a good VR headset to promote out passthrough content of ours really well.
