It's not the first time since the construction patch and it surely won't be the last time. My game freeze after 1h30-2h gameplay. Seems changeing loadout often accelerate the crash. Too often I crash within the minute after pull a MAX, ESF, tank or whatever high nanite cost thing, witch is lost.
The easier way to deal with it right now is turning the Particles from whatever you have to Low. I have been seeing consistency in the fact that I had mine on high and crashing between 48-94 minutes in game. Once I put it to low, I was able to go to about 3+ hours... although the game has also started showing some audio issues as it gets later into the game with a lot of the Gorgon/20mm firing sounds going.
Exact same circumstances for me. I think it's related to the bug where in big battles, it sometimes takes a full 5 to 10 seconds before my equipped items show up and become selectable when changing loadout, spawning (in sundies, pods, gals, etc.), or even just exiting a vehicle. I can move around and attack with the item selected by default on spawn, but I can not switch to another item. For example if I died as a medic while using the medic tool, if I spawn again as a medic in a 96+ battle, for 5 to 10 seconds I wouldn't be able to select my gun. I would be locked to carrying the medic tool. I can use it as normal, but I can not switch to anything else. This is incredibly frustrating when trying to quickly do something on spawn, like mine a nearby sundy or kill a spawncamper. This bug as well as the crash seem to be connected to terminals, loadouts and spawning. Crashes for me has always happened shortly after reequipping or spawning a vehicle. Since I'm usually leading a squad, this can mean disastrous consequences. The loss of deployed sundies and placed beacons can seriously impact chances of a successful cap or defense, not to mention yeah, the loss of freshly-pulled maxes and vehicles.
