question about texture sizes

[KAKTUSDIGITAL]

If I have RT GPU set to downsize textures to 512X512, will smaller textures be upsized to 512? then sent across to the gpu?

I've had some issues with HDR's. I have 7000X3000 hdris which dont seem to work properly when i have them plugged into a dome light ( I get wierd artifacts and console errors about memory)
However, if i make a cylinder, then map the same HDRI via a 'bitmap' map it will appear properly.

Cheers!

All textures are resized to 512x512, even if they are smaller. The exception is environment textures (so that you can get better reflections) - V-Ray RT will attempt to load them at their full resolution, which is why 7000x3000 will likely fail.
