Nothing Valve related, but since Windows 10 is the new thing, this thread is propably inevitable. I haven't upgraded to Windows 10 yet, since I kind of don't wan't to leave Windows 7. Altough if someone has upgraded, then why not share your initital thoughts on this thread? Is it worth it or not? Also, if you're not aware, DX12 is only compatable with Windows 10, so if you're interested in that, it's either upgrading or wating for Vulkan's glnext API to arrive. But even if you upgrade, you're only preparing yourself for the future since DX12 has not even beeen entirely activated. People have been experiencing less framedrops, so perhaps it's well optimised for once. At the same time, I have heard of some privacy issues... Share your thougts!
