@bloodroses there is the pixma 8k (3840*2160, FOV:220 ) (which is not a real 8k, because the cable didnot support more than 5k of transfert) and a pixma 8ks (or x) which will be true 8K.
the problem: you need a huge PC.
apparently the StarVR will have a bad resolution of 5120 * 1440, this is far away from a good resolution for a large FOV. Specialy the vertical resolution of 1440 which is a critical one. as per Samsung Odyssey's early tester, a resolution of 1440 * 1600 offers a noticable difference from a 1440*1440.
The StarVR didnt describe the type of screen, LCD will be a bad choice for a top VR, they have to offer an OLED system.
so finally... dont put your expectations too high on StarVR until they use a better vertical resolution and OLED screens.
