Shrinking texture size outside of sim better performance?

Hi all,

Does anyone know -

If I run an airport with 4096 textures with the sim set to 1024 (for the sake of my puny VRAM amount), does this lower in-sim performance versus shrinking the textures to 1024 outside the sim and running at 1024 in the sim?

Any experience/ideas appreciated!

Kind regards,
Rudy
