If I downgrade will it ruin compatibility with newer openGL games (portal, hl2, ext.)?
Like acdcfanbill said, as the DLL is only in JKA's GameData folder, it's only going to affect JKA. Also, only a small handful of games use OpenGL nowadays (mainly games running on the iD Tech engines like ET:QW, Prey, Q4, etc). The rest of the games like Portal and HL2, use DirectX.
