Like the title says, I finished the game in a 100 hours of play without a single crash, I turned off both updates and cloud support in Steam. Yesterday I started Steam to find that both cloud and update was turned back on and my game patched itself.

Now I'm having one crash after another. I'm happy you are trying to fix your game, but forcing an update on people who had no problems with the game and wanted it to stay that way is bogus. If I had wanted the patch I would have activated updates by myself.

That's strange. I don't have automatic updates disabled but I do have cloud computing disable and that hasn't changed.

I was surprised as well as disappointed about it.

I'm now going through my mods one by one to see which one is having a problem with the patch, not happy about this at all.

I had them (updates and cloud support) turned off. After the patch came out, they had not been turned on, but the patch had been applied. That was before we knew there might be problems. I got a zone alarm message asking whether I approved of what falloutnv was doing, said yes, and then lost the game till I removed invalidated.

Exiting and restarting Steam counts as a manual update. Automatic updates are simply whether or not you want them applied during a Steam session, instead of at the beginning of one only.

Yep that feature never worked for me. Only way is to go offline.

Is there any way to revert to the previous version of the patch? The latest one has made the game screen constantly resize every frame, making it unplayable.

Help!

The same sh... unpleasant thing has right now happened to me. Now I can't even restore my old backup. Because when I do, Steam connects to the Internet and downloads the patch and doesn't activate the game without it.

I haven't noticed it earlier. But then, I've never needed to disable updates for a game on Steam.

After this is over, I'm going to offline mode and making my firewall disable Internet access for Steam client without my confirmation. Hope this will help me in the future.
