No disagreement here. But before the introduction of Steam into China, Windows 10 was closing in on Windows 7 very quickly. Actually, even up to the beginning of this year it was. I made this post in February and I remember checking the Steam hardware survey and it looked like Windows 10 was rapidly closing in on Windows 7. But when you look at it now, there has been a massive surge in Windows 7 users, which can easily be explained by the increasing amount of Steam users in China. Even the most popular language on Steam is no longer English, it's simplified Chinese. No, I said that the vast majority of the Windows 7 copies in China are pirated. Sorry, but Windows 7 is garbage compared to Windows 10. Gaming on Windows 7 performs worse than on Windows 10, and even more, the OS is much more vulnerable to malware than Windows 10 is. People can do what they like, but any friend of mine that still ran Windows 7 would get a long rant from me telling them why they shouldn't be. Not as simple as what you're saying. Shader model 6 is fundamentally incompatible with DX11 and Windows 7. It only works with DX12 and Windows 10. It seems to me they are making a clean break from the legacy programming and modernizing their engine as much as possible, likely for the performance and efficiency gains. To gain as much as possible from DX12, the engine needs to be completely rewritten to take advantage of it, and thus any thoughts of DX11 need to be abandoned. So for them to even contemplate using Shader Model 6 tells me something. This will probably be the most technologically sophisticated title of the year. Also, I would bet money that the majority of the people that are interested in Metro Exodus, are not running Windows 7.
