Ryuubei: errrr nope, Valve still have the same old refund policy, telling you to get stuffed. And yes they did say no to the EU courts, just as they said no when the courts told them to allow people to trade in their steam games
Actually, I can program and have developed some smaller games. And as I see it, the most likely thing is that they skip some OS-abstractions in order to get better performance. This will therefore lose some settings. And I doubt that they have made an input function like this: Lillesort131: How do you know that this feature ever was there? I suppose it has never been there but I would love to see a source of that claim.
Also, relevant xkcd: https://xkcd.com/1475/.
Ryuubei: They use a piece of software coding to OVERIDE the hardware coding. That is the crux of the problem. So yes, it's removed because the software overides what the OS is telling the game. The OS tells the game its a left handed mouse set up X way. The software in W3 says screw you i want left handed mice to be Y way. The EXACT same issue that W2 had and still has. Also, relevant xkcd: https://xkcd.com/1475/.
input = screw_you("I want left handed", osInput());
It is more likely that they simply didn't think of this. The code probably looks like this:
input = raw_input();
You could also just code your own driver or make the change in hardware if you want to force it to invert the mouse. Also, if you would alert them nicely of this issue, they will probably fix it within the next days.
