[quote 496013]Because graphics cards were shit back then and when Gaming progressed, they stopped supporting Dxlevel 6 and 7 (yes there was also Dxlevel 6), because by the year when they got rid of Dxlevel 7, most of people had a decent PCs and they wouldn\'t waste their time supporting Tf2 with Dxlevel 7
They still support Dxlevel 8 just because they are aware that not all players can handle dx9, but expect them to get rid of Dx8 in next few years, they most likely gonna implement Dx10 and 11 into Source 2 engine when it gets released.
[b]tl;dr Dx7 died, expect them to get rid of Dx8 in next few years, most likely when Source 2 gets released[/b]
Thats what i think at least[/quote]
That sounds like the most reasonable explanation, thank you!
