Something's gone wrong with my computer. When I bought HL, I got a few mods with it as well (Blue Shift, Opposing Force, Counter-Strike). With Blue Shift came a High Definition pack for all HL mods (And the original HL). However, I recently downloaded Wally, and after unpacking my PAK file, I played HL single player, only to discover that it had gone back to low-res graphics. However, my other HL games were unaffected. Does anyone know how to fix this problem? I've tried reinstalling the HD pack but it didn't do anything.
