Citar3. Misleading marketing campaigns
The launch strategies for Windows Vista and Windows 7 were both accompanied with an immense marketing push by Microsoft for DirectX, in which they showed 'before' and 'after' screenshots of the different DirectX versions. Many gamers now think that switching from DirectX 9 to DirectX 10 magically transforms graphics from stupidly dark to normal (as in the comparison above), or from Halo 1 to Crysis. Game journalists proved that there was no difference between Crysis DX9 and DX10, and that its "DX10" features worked fine with DX9 by tweaking a config file. However, despite its obvious inaccuracy, the marketing has convinced many gamers that DirectX updates are the only way to access the latest graphics features.
