Can close as duplicate we’ve had quite a few of these issues, #1035 got closed though it contains the most reports of Source + GoldSrc ingame chat font issues. https://github.com/ValveSoftware/halflife/issues/386 is still open for GoldSrc, https://github.com/ValveSoftware/Source-1-Games/issues/67 for Source.
Closing per the last comment.
Nothing extracted yet.
As discussed in this thread
http://steamcommunity.com/app/221410/discussions/0/846939071403952294/
fonts in TF2 and CS:S are displayed too thin and almost unreadable on bright backgrounds.
Any way to change font (size)?
