Simplify (remove subsurf) for Object Info/Collection Info nodes
Object Info and Collection Info are powerful nodes in the geometry nodes workflow and serves several purposes, like combining and modifying objects non-destructively.
One of the pain points in this workflow is the subsurf modifiers on the original objects. If the final object needs a subsurf modifier and the original model needs one to display correctly in viewport. Accidentally enabling both can cause blender to slow down, freeze or even crash. That's why a simplify option can come in handy.

If the object info node allowed accessing the mesh data directly, that would solve the problem in many, but not all, situations.
Another way to solve your described situation would be 1 source object with no modifiers. 1 object sharing the same mesh data as the source and also having its own subdiv modifier. Then on the geometry nodes based object use the source object instead of the subdivided object.
you meant subdiv, subsurf=sss
