High resolution rendering

Hello everyone, I am rendering a 9000X4500 resolution panorama Image rendering with massive landscape (with 3d grass and shrubs), my GPU is constantly crashing I had used Nanite for all foliage still the same problem persists. Same with the interior scenes (only furniture)

Render setting -
using movie render queue for rendering, used high resolution image option in movie render queue, screen percentage in console command is 100%. In panorama rendering number of horizontal steps is 10 and vertical steps is 5(using less values then mentioned is not proving good quality images.)

My system configuration -
Intel I9 10th generation
64 GB RAM
16 GB RTX A 4000 GPU.

I hope the process by me is correct or is there any other way to do it? also please confirm regarding the configuration too. Would be glad for any help provided trying to solve this from a long time now.

Thanks in advance.

Hi,
Did you find a solution to render very high res. image?

We have same problem on a 14000x10500 image render from UE5.

If someone have a solution, thanks to share.
