From Black Mesa: Wiki

Will black mesa's new shaders have shader model 2.0 fallbacks? If not, then the X800 needs to be removed. --QUINTIX256 17:57, 7 December 2009 (UTC)

i'm thinking of changing

"For more details, check the list of Source powered games that include SDK Base."

-to-

"If "Source SDK - Orange Box" Does not appear on the tools tab in steam you must
purchase a game from this list"

Or something similar. I think this rewording makes the system requirements more black and white for some users who are unsure about them or for people who have a youtube account.--FireTime 06:47, 25 May 2010 (UTC)
