The Winter of a Hundred Years

Back home, one ice age during the two and a half million years of the Pleistocene lasted a total of 100,000 years, ninety thousand of intense cold followed by ten thousand of milder interglacial weather.
But in this alternate Earth, we've been in an ice age for five million years, with glaciations lasting 150,000 years followed by interglacials lasting 12,000. Would a longer Milankovich cycle result in a different climate, a different landscape and a different extent of the ice?
