Just a quick post to say that, if you are experiencing Fallout 4 CTDs (Crashes To Desktop, where FO4 closes without any messages or anything and you are left staring at your Desktop in Windows), I want to let you know It's Not Just You™ - as I am finding I am experiencing this as well, lately...
I haven't looked into Forums specifically for this, but perusing Forii over the past year or so, where they are talking about Fallout 4 and Crashing, it seems to happen a lot to many people anyway, unfortunately. I myself wasn't experiencing this very much, gladly, until just recently, when playing FO4 again (and spending way too much time building up Settlements instead of getting Quests done), I was testing out different Game Recording Programs and started seeing this happen.
I'm happily playing Fallout 4, getting frustrated at the Building mechanics or shooting some Raiders attacking my Settlement, when all of a sudden, BOOM - desktop image and icons. No message, nothing. Fallout 4 has closed itself instantly. I of course start it up again and begin to see where I last hit QuickSave or the game automatically Saved for me - but this has happened a few times in a row now where BOOM - the desktop greets me and icons appear. No message, nothing.
So, I tried to pay attention to what I was doing or what was running as Background Tasks - and the one thing I found, that when I changed it, the crashes stopped happening?.. I was recording with SHARE, NVIDIA's new version of ShadowPlay, their game recorder that is included with their Graphics Driver. Interesting. I have up 'till now had no issues with SHARE, enjoyed testing it out, taking Screenshots with it and testing out the various Quality settings and forgetting about all of those tests and never writing about it. It seems to have great performance (very small performance 'hit'/effect) and has a decent amount of options/features.
I then briefly tried some other game recording programs I have purchased over the years, Playclaw, Bandicam, Mirillis' ACTION, and none of them had any Crashing occur while I was using them (although Fallout 4 didn't seem to like to start up with Bandicam running sometimes [but when I started the game first then Bandicam, it recorded fine]). Hmph. That's too bad, I was liking SHARE. I might go and mention this in the Official NVIDIA Forum, if noone else has recently. Perhaps this is just a temporary issue in this game and their Drivers, in this version.
I am running NVIDIA GPU Driver Version 382.53 in Windows 10 64-bit, on a GTX 1060 3GB GPU, as of the date of this post.
I mention all of this because, I was not really experiencing any Crashes-To-Desktop with Fallout 4 prior to thinking of testing out SHARE for a while, just a bit ago. I am Level 42 in the game, after 'starting out a second time' and enjoying taking notes and screenshots for some future posts on it, while I slowly build and shoot my way through The Commonwealth... Where was I? Oh yeah, the crashes. It's sad, but I want others to not feel alone. If you are experiencing Fallout 4 closing without any error messages recently, and you have an NVIDIA GPU, just letting you know - It's Not Just You™...
