New Grand Theft Auto The Trilogy HD texture packs have been released for PC players, further improving the visuals of this remastered collection.

Last week, we already covered some of the first mods for this remastered trilogy, and we now have the very visual enhancement packs for the collection. Created by modders ‘QTmodz’ and ‘Instanity666’, these HD texture packs improve the road textures in Grand Theft Auto III and Grand Theft Auto: Vice City, while greatly enhancing the visuals in Grand Theft Auto: San Andreas.
