My headache's fading at last (don't spend so much time at your PC or you'll end up like me), felt like saying...
I hosted OG for Lepidopterus yesterday. There was some lag and I soloed more difficult parts but we both had fun

BTW, do you know if it recognises XB1 and XBS? Parsec has some option for virtual gamepads? Whatever it means... It was set to XB360. Lepidopterus played with XB1, I just had to pick it in the game's settings where it was referred to as XB360 and it would work just like that.
