The Half-Life 2 RTX demo takes five times more HDD space than Half-Life 2 itself

After what feels like eons of waiting, the Half-Life 2 RTX demo is finally here. You can try two levels of the fan-made enhancement to Valve’s epochal FPS right now, turning the classic shooter on its head with an array of game-changing new visuals. This comes not long after Valve itself enhanced HL2 and briefly gave it away for free, so this no-cost demo is the perfect way to make one of PC’s most important videogames of all time look even better. You might want to clear some hard drive space, though, because it isn’t exactly a small download.
