If we're going to go along those lines, my GPU is not installed. Everything is coming out via the line printer.
My visualisation of images rates as 0/10 - power cut in a basement. I can't even create a colour (except the inside of my eyelids on a sunny day). Not even aware of a visual component in dreams.
But I can mentally 3D model. I can sort-of "just know" how things interrelate that is more an unconscious time and distance journey around the thing. It works well enough to plan a model, something I want to build from wood, or redesign the kitchen with an idea of where the possible clashes are, before I hit paper. So the spatial sense is there - somehow.
Explaining it without a lot of hand-waving "I just sort-of know" is a challenge I also fail at. It's more like asking you to visualise something non-visual like honesty I suspect.
