The game is great, but unfortunately the remastered version seems to have some nasty bugs. The worst is input lag where I'll have to hold a key for three to five seconds before it'll register. Only solution I found is to make sure GOG is minimised, then close things like Steam, Discord, browser, xl whatever can have input. No idea what cause it, but that's the only thing I've found that works.
As GOG doesn't let you select which DLC GOG will ALWAYS try to update to include it. So, I downloaded the offline installer once, and then install from that. Problem solved right? Nope. Even using the offline installer, the bloody DLC still wants to download every time you play. What it provides can be done with mods, for far less space on your SSD.
