I'm not a developer by any stretch but after experimenting with enabling ReBar in the Nvidia driver through Nvidia Inspector I noticed textures would take much longer to load in than when it was not enabled in Spiderman Remastered... maybe, Again not a developer, FSR2 in this title is also enabling ReBar ?
Rebar is completely separate thing to upscaling tech but yeah could be down to rebar maybe, not sure if bang4buck has it enabled for this or not on nvidia side. I was wondering if it might be a FSR upscaling thing but there is no way it would render textures like that.
