I just checked twitter and a programmer at Id Software has confirmed that a patch is on the way.

He also notes that they are added flashlight shadows back in, but warns due to the placement of the flashlight in BFG they wont look very good.

No ETA on the patch was posted, but considering that Bethesda usually likes releasing patches for all systems a game is released on at the same time, usually, it probably wont be until the Xbox 360 and PS3 versions pass certification.

I hope this makes some of you feel better, I know it did for me.

Is it possible this to be added in DOOM3 BFG ?
