>driving up the PSVR2s BOM with an on-board processor fast enough to do it The Quest 2 can do SLAM on the head set plus the 2*2K resolution 3D rendering in real time on a 4 year old QUALCOMM chip running Android OS on top and it costs less than the PSVR2. So Sony can definitely afford to put a processor in the headset just for the SLAM compute alone since the 3D rendering is done on the PS5. The chip in any optical mouse is a low resolution camera and DSP computing SLAM algos at hundreds of times a second and costs peanuts. VR headsets have more resolution to process and account for the third dimension in space but they also don't have to process the entire picture but just the differential movement of the LEDs captured in their blanking intervals, processed as white dots in B/W images, further simplifying things. So pretty sure the PSVR2 SLAM compute can be done on an ARM chip or FPGA worth ~ 10 USD nowadays.
