From what I remember:

Owner locked all of the devs out of access to the project

Some racism/homophobia

And some other things i dont exactly remember rn, but because of this stuff the devs all left and forked into Prism so im not even sure is Poly is still being developed, and if it is id be sceptical on how safe it is to use given who owns it.

A man can dream

Til russia inevitably breaks the ceasefire and they cut off the intelligence again.

Honestly motion blur done well works really well. Cyberpunk for example does it really well on the low setting.

Most games just dont do it well tho 💀
