In every case, Denuvo balloons the exe file size by 4-5x (we're talking 400-500 MB for a <100 MB game exe), can increase loading times between 10-400%, and in most cases, lowers framerates between 10-40%, and can introduce microstutters. There are a few outliers where Denuvo's removal coincides with worse framerates for some reason. But essentially, removing Denuvo speeds things up a lot, especially download size and loading times.
