I made a previous thread in which I said Pimax shrank vertical FOV in firmware 255.
I was wrong. They didn’t reduce it in the firmware. They reduced it in Pitools itself.
This is easily verifiable by reverting to Pitools 220.127.116.11_R255 or below.
I first noticed this when updating from the Pitools .180 beta to .253. I saw what looked like an obvious drop in vertical FOV. But no one else seemed to be talking about it, so I wondered if perhaps I’d imagined it.
But I wasn’t the only one who saw this. User grodenglaive on the Pimax reddit forum had also noticed it too, and he suggested I try Pitools 2.45, because it still had the larger vertical FOV. So I installed .245–and immediately saw vertical FOV increase back to the level I’d seen before updating from the .180 beta! (In addition to shrinking vertical FOV, it looks like they changed the overall shape of the
view, and this makes the edges a lot more noticeable in general, IMO).
I don’t think Pimax should reduce FOV, because increased FOV is the main reason I went with Pimax in the first place, and I know I’m not the only one. At the very least they should acknowledge that they have reduced vertical FOV and make this reduction optional in future updates.
Before anyone weighs in to suggest that this decrease is due to the new higher refresh rates and can be fixed by dropping back down to 90hz, this is simply incorrect. Nor can it be fixed by disabling Hidden Area Mask or any other setting. It is simply a software reduction of vertical FOV in Pitools itself, and anyone doubting this can revert back to .245 or .180, etc–and see for yourselves.
Pimax–PLEASE MAKE THIS REDUCTION OPTIONAL in future versions of Pitools.
