From what I understand, your save games from Witcher 1 and 2 can have ties into The Witcher 3, I've seen people with tattoo's from Witcher 2 still be the body in Witcher 3.
If this is the case, if I have the first 2 games on Steam but thinking of getting a GoG copy of W3, will the saves still be read or is it better to stick to all 3 games within steam?
Its fine but remember W2 on steam will use the steam cloud so you will need to disable that so it saves to its normal path on your HDD/SSD.
Anyone know what 'Post Process' sharpening does?
I set it to High.
So mouse + keyboard or 360 pad for this?
In regards to cloud saves, does GOG galaxy do something similar or do I have to copy my save file onto a USB if I want to play on another PC I installed the game on..?
I've always felt you get better performance with fullscreen, because that window has 100% focus. I also get input lag in borderless window (more noticeable in other games though).
