Continuous Unreal Engine Crashes

I've been experiencing continuous crashes usually about half way through the second match of a session, so about 30-45 minutes in. The game simply freezes, returns me to Windows and then a crash reporter for Unreal Engine appears. This is becoming even more frustrating as I'm losing out on roughly half the in-game experience I should be earning due to the game marking me as having quit the match/timed out. Anyone else had this problem?

I'm running:
Windows 10
Intel(R) Core(TM) i7 CPU [870 @ 2.93GHz]
8.00 GB RAM
64-bit Operating System, x64-Based Processor

Thanks guys.

Crashed in approx 60% of games in 13 hours playtime. After changing to windowed borderless via in-game menu I've had zero crashes. Played 4 hours after changing.

Still stuttering -> Devs are of course working on optimization

Ps: RAM could be the bottleneck
