How can I stop my viewport texture rendering in 8-bit whenever I get too close?

how it works right now is that I set the portal camera’s viewport size to match the shape of the quad mesh that it’s rendering to and I multiply it by 20,
bUUUUUt when I try to multiply it with a bigger number (i.e. setting the viewport to a bigger size) it throws my fps into a lake with cemented shoes…

is there a way to put this all in shaders? or something?
