undo a modifier?

second question…

I added a subdivision modifier and gave it a count of 4 for subdivisions and 4 for render… and saved it, my bad! It made my PC real jumpy/sticky, even when I reopen the file. is there anyway to undo this?

. is there anyway to undo this?

If you applied the modifier (Why ?) and don’t have any undos (Ctrl+Z) because you saved and then reopend the blend then the answer is No.

hmmmm… bummer…

appreciate your time.
