Talked to some folks at the office. The game supports 1080p, but the game resolution on PC is the same as the original release.
The resolution can go up to 2560x1440
Thx but I dont understand you really , because You say the game support 1080p but the PC game resolution is the same as the original release.The original Doom 3 release in 2004 ( max resoultion is 1600x1200 ) so how 1080p ? Or why You say the resolution can go up to 2560x1440 insane resolution ?

sry I just not understand that.
Ohh wait So You say the game texture is the same old Doom 3 2004 so 1600x1200 but Now We can Use better resolution 1920x1080 and higher ?! And Doom 3 BFG later have ultra texture pack on PC ? Just like Rage ? So 1920x1080 textures maybe later with patch ?
