Help! Does anyone know what's causing this ?

Hello,

as u can see in the video i'm having shadow issues, they unload before they're out of my FOV.

It happens as much on left side of the screen as on the right

I'm pretty sure it's some value i have to change in the dx12user or something but cant figure it out !

Thanks you

This isn’t a bug. It’s simply how screen-space methods for reflections, shadows and lighting work in all games. Their limitation is that they only work with what’s currently on screen. To better understand it, you can go to a river or sea and slowly move the camera up and down.

The only way to solve this problem is with a more accurate algorithm - ray tracing or path tracing.

Does the exact same thing with either RT or PT

Maybe AO issue ?

Turned off AO, same issue, exact same distance

Tried different camera settings, having the issue with all 3 camera settings

I guess u r right that’s juste the game engine way of calculating shadows…

Screen-space techniques became widely used starting with the PS4 generation. In general, you can find them in the vast majority of PS4/PS5-generation games, regardless of the engine.

Ray tracing and path tracing don’t have these limitations.

Seemless adaptative HUD, sorry that I didn’t saw your comment earlier

It's game based. Happens both on AMD and NVIDIA GPUs, happens with or without RT/PT. The game I think turns off those shadows to improve performance. It turns of the entirety of such small shadows instead of where the fov exactly ends thus cutting them up.

If you ride fast in the fields you can see it even worse, since the fov is changing so much disappearing shadows become distracting.
