I’ve been using the .180 beta version of Pitools since I got my Pimax 5k XR and just updated to Pitools .253 (which means flashing to firmware .255).
Right away I noticed that I could now see the borders on the top and bottom of the image with FOV set to “Large” where as before I could only see the bottom one. I’ve tried readjusting the headset angle, tightening the straps, etc–but it’s definitely a change with the optics themselves–either in the firmware itself or in Pitools.
I tried going down to Pitools .249 (which is still using that .255 firmware) but this made no difference. So I’m thinking that maybe the reduced vertical FOV was introduced in the .255 firmware itself–the same firmware that introduced the “Potato” FOV mode.
Before I flashed to .255 I’d spent many hours trying different depths of padding, shifting the headset, tightening straps, etc, trying to maximize FOV, so I had a really clear idea of what “Large” could look like on my headset and I know for a fact I can see the top border now no matter what I do, where as before I could adjust things so that it wasn’t visible.
Maybe if I hadn’t been paying such close attention to it before I wouldn’t have noticed, but I’m still surprised no one else seems to have commented on this FOV reduction. Since FOV is the main selling point for Pimax, this seems like kind of a big deal? Or at least it is to me …
