Tearing / Flickering

So yesterday I got a fresh new ps5 (slim digital) for poe2 specific !

I did lower the res to full hd (my tv is 4k but didn’t really think I need that I preferred to help the fps :p).

Upscale mode was in default NIS, in those settings when in town and some areas the screen seems dizzy a bit and it’s hard to explain - not to all the areas but in some, like there are some horizontal lines going down.

Change to bilinear fix it by 99% of the cases but quality really drop!

Is it just me ? Ps is brand new - tv is good and other games have 0 issues so guessing (and it’s logical since it’s a beta game 6 days in).

Thanks to all!
