After more than a month, update 5 finally made the game run perfectly at 100+ fps without a single crash on my system. But today, NIS released update 6 and crippled the frame rate down to a ridiculous 35fps, while also reintroducing all those crashes. Do these people even know what they're doing? Unlike Steam, GOG doesn't allow its customers to roll back to older, functioning versions of their games, so this product is pretty much useless to me now.
