Hey,

I am using 4.12.5 and I have changed the defaultengine.ini to set the max as 8k:

But in game it still displays and shows max in game as 4k:

Does anybody know why this might be happening?

Would it be limited by my GPU being an Nvidia 670 TI?

I followed this document to set it up but can’t work out why it isn’t working for me:
