Oh god, here we go.
Please explain the fundamental and/or technical difference between Win10 and Win7 that prevents the inclusion of DX12 in 200 words or less. Please double space and write in an APA style. You will be graded on sounding like a MS shill and using asshattery such as "UXP", "progress", "Unified platform", etc. This assignment is worth 1 internet point.
What "could be" is immaterial, because it will never happen. Ever. Ever. DX12 will never appear in 7.
