Ideas
Prior to the most recent patch 1.1.2.0, I had experienced just one major crash (black screen, fans full blast, PC unresponsive, reset via PSU). What triggered it was after a Gauntlet match, went into the shooting range for a bit, then faffed about gun customization. Game is launched from Steam, so after booting back into Windows, repaired game files. Played 6 Gauntlet matches consecutively, tracing the same steps after each round without being able to replicate the issue.
Post-1.1.2.0 however, I can't even launch the game leave to get a drink or whatever without coming back and finding my PC completely unresponsive but still turned on. Other times it would crash just sitting in the menu with me doing and touching absolutely nothing.
During the beta was far worse, couldn't complete a single conquest round before the inevitable crashes and it would become more frequent unless I gave it a pause in between sessions. I thought it could be a corrupted Windows despite no errors found via SFC or DISM commands. Went ahead with a fresh Windows 11 install anyway. Even went through the trouble of changing my PSU with zero improvement based on suggestions found under countless threads. Did an entire night's worth of memtesting, countless hours of OCCT and AIDA64 testing. Nothing could crash my PC except this wonderful thing called BF6. Found a thread where a gentleman found via WinDBG that Javelin seems to be doing something funky with the kernel and that it is more than likely the root cause of the severe crashes. When I wanted to go back to the thread it was gone. Could not locate it anymore. Highly suspect, if you ask me.
I'm glad I did not put down money on this game and decided to wait for the F2P version i.e. REDSEC to release and put my theories to the test (fresh Win11 install, latest drivers, latest BIOS).
Apologies for the long winded comment. Just want to cap it off by saying I flagged the game on Steam, the least I could do. Will probably try to contact Steam support, but I doubt they'll help. Likely just redirect to EA, I reckon.
