Just experienced the third UE4 crash in one night. This is the first time dealing with the UE crashes, even after the last major update where this was common.
#3 UE4 crashes in a single session

Usually checking the validity of files keeps the app steady for a while. I have a question actually - how much RAM do you have and is it working in dual channel ? I have 2x8GB RAM working in dual. I did memtest before the game and it was OK. After playing I made another test and it kept finding faults at some point. I suspect its a RAM fault that keep crashing the game at certain point or at crossing first 8GB of RAM. I bought another 16GB card today to check if makes the game more stable. As seen in Resource Monitor the game can block as much as 12GB of RAM, mostly on snowy maps the demand is very high and I get the worst stuttering effect. When the RAM does not work I see 'hard faults' appearing and apparently the pagefile is being used instead of RAM which amplifies this stuttering
Thats just an example snip from the apps - you can run Resource monitor in the background and see for yourself how much RAM is needed. As an example on ElsenBorn ridge I had 1-2GB free RAM but regardless of this and dual mode I was hitting hard faults and SSD drive backup memory must have been utilized in those moments. RAMtest you do obviously when your system is fully unloaded

The thing that irritates me is that these issues are not there before the update and then "magically" appear. I did validate my files and my RAM is sufficient. I noticed a Microsoft security update and updated my graphics driver. I didn't have a crash last night but I think there was a close call at one point. It's still early to say "I got it fixed" but I'm hopeful.
