i don't know why people are blaming GameWorks again. Even if you turn those options off game has issues. Turning all GameWorks options except smoke have very little impact and again smoke is volumetric and can cast shadows so of course it is demanding.
Yeah, I like having options for ridiculous graphics effects even if they kill framerates. Makes me look forward to a replay with better hardware. It's like the old days!
That's different than a shit port with awful optimization and worthless, unannounced DRM. I hope Steam's refund feature bites WB in the ass.
