I thought this was a source game, legit straight up, it looks, feels and sounds like one.
And that made me make an autoexec file for changing the game resolution, because it straight up doesn't, i'm having performance issues and tried changing resolutions to run it better and it won't let me, i can select the resolution but it doesn't change, plus i feel like low res would feel better to play, awesome game tho, wish it didn't run so tanky.
