The HD collection has a variety of missing effects. Depth of field is gone, transparency textures on Dante's hair is gone, and so much more are gone or replaced with something that is badly HD upscaled. You can forget about style switching without using a menu in DMC 3; that is still a Nintendo Switch exclusive feature unfortunately (Bloody Palace Co-op is also still a Switch exclusive). PC is still the definitive place to play DMC 4 SE. It took GOG more than 4 years to have the missing hauntings be restored in the PC version of Silent Hill 4: The Room. More than 4 years to have the true SH 4 experience. With a lot of community support and support from Capcom, hopefully, the true experiences of DMC 1-3 will be preserved.
