Comodo FW/IS 10 : blocks any 3D games ("process has stopped working" error) even with all security off but can do what I "need". W10FC : dev said that you don't need Windows Firewall for it to work but I can't have any of my ports to be stealthed without. Can block hostnames but you can't import a list (while Comodo does) if i'm not wrong. Windows Firewall : you can't block domains/hostnames (for adblocking system-wide purpose) and I don't want to bloat my HOSTS file (slow DNS client initialization and huge memory consumption). It's hard do find a great replacement.
