Hi
@Zerion !
You are right. It's not heavier, but it renders more pixels. As explained some posts above, let's talk about 1080p 16:9, for example: as the camera has black bars on top and bottom, it was rendering 1.6 million pixels, instead of the 2 millions of "full" 16:9 1080p, so in last version I increased the resolution to compensate it and to really render the same pixels as a traditional (16:9) 1080p picture (2 million pixels). So, in 1080p 16:9 you are now rendering around 25% more pixels so you can expect the same FPS loss.
But I'm thinking about reverting it, if you, hardcore users, don't think it's important to exactly render the exat number of pixels of traditional resolutions based on traditional 16:9, as the world is very diverse. (And because the upcoming forest scene is too heavy).
Said that, maybe higher scores and a more smooth experience is preferable, isn't it?
What do you all think?
About the Path Tracing mode error, I noticed that too in some builds of the project (solved rebuilding, without any other change), but wasn't able to reproduce. I think the current UE version may have a bug when packaging, as other related issues happens. But I will update to UE5.5 as soon as it's available, and it can bring some very cool improvements!
