cl_showpos and friends (cl_showfps) are way too big on old versions of L4D2, which leads to hardware (dis)advantages

[ImAciidz]

Normally I wouldn't complain about this, but going into the future, more and more people will have higher and higher resolution monitors. Showpos is much less useful at 1440p, and pretty much completely useless at 4K. Specific things like ladder launches rely on being able to read the third positional coordinate of showpos, which is literally not possible at 1080p. Lowering resolution can lead to more input lag/other undesirable effects, so we should really consider fixing this (make it work like every other source game/later versions of L4D2).

The bug is fixed in version 2.1.2.5 (July 2nd, 2013) - https://left4dead.fandom.com/wiki/Updates_(Left_4_Dead_2)#July_2,_2013_(2.1.2.5)
