Isn't the SLAM tracking processing done on the headset itself and then the computed movement data sent to the PC/PS5 via USB?

- jsheard 3y agoIs it? I haven't seen it definitively confirmed either way, but intuitively it would make more sense to do SLAM on the PS5s main processor rather than driving up the PSVR2s BOM with an on-board processor fast enough to do it. They have to stream the camera frames back to the PS5 anyway for the passthrough feature to work.

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.
