In the "Caverns 1" stage, there have been moments, usually when the Cacodemon attacks early in the stage and you walk outside to look out over the lift you rode down, with lava all around, that the game was dropping to about 1-2 frames a second. It never crashed though. However, after grabbing the required key from deep down in the same stage, when I come back up, I climb all 3 ladders, and at the top, when I round the corner to get out, the game stops. I can't open my Xbox menu with the Xbox button, though I can hear it 'trying' to open. I can open the disc tray and have it jump back to the dashboard, but the game becomes entirely unresponsive. Game was installed, so I uninstalled it, and it still froze. I'm unable to progress or finish the game.. especially when I'm so close!

EDIT: I cleared my cashe, and it still froze.

I reloaded my last autosave and ran through it just fine. Weird.

Hi guys, just been doom3 on the bfg edition, just trying to find the monorail and the game slows its frame rate right down several times and then recovers but every time I open the same door with an armed guy behind it, the game completely freezes up. My game is not on my hard drive and all of my other games are up to scratch on my console, please help, regards, Rich.

yeah same here except its the communications maintenence area that is dropping framrate to unplayable levels...please fix this!

It happened to me too in that identical point.
I've managed to proceed in this way:

Just before the door with the zombie soldier there is an hole on the wall to a passage that is connected with the guy:try to throw some grenades inside the alcove... after 5\6 grenades i've tried to go on and it worked,not freeze (but stil some frame rate drop)...

Need patch.Patch for this framerate\freeze bug and button customization.

Sadly, I'm having the same issue. It doesn't occur very often but I've experienced this more than once, twice leading to a system restart. On one occasion early in RoE, my image was reduced to 1-2 fps without crashing, causing me to back out to the main menu. A title update would not go unappreciated.
