I like using new technology as well, but Windows XP still has it’s uses, I don’t really do anything online with Windows XP so I’m not all that likely to get hacked.
I will stick to using Windows XP and DirectX 9 for another 10 years or 10+ years.
Personally I don’t care if DirectX 9 has Tessellation like DirectX 11 and so on.
Video games can still be developed using DirectX 9 and running on Windows 7 64-bit or Windows 10 64-bit. There’s even a 64-bit capable build of DirectX 9.
