BF6 Causes Complete Blackout on RTX 5070

I have the same exact CPU and motherboard (with latest BIOS F21 and latest chipset drivers), and 32GB of DDR4. Like you, my system passes all the stress tests without as much as a hiccup. Regarding the chipset drivers, they're almost 6 months old (latest) at this point and I'm quite sure AMD is not going to release a new one anytime soon.

GPU RTX 3070 with NVIDIA driver 581.80. 

I am noticing a trend with a lot of systems running Zen3 Ryzen 9 CPU (especially the 5900X like ours) experiencing the dreadful black screen crash. Had one crash occur after playing one round of Gauntlet, after which headed into training grounds (shooting range) and into gun customization. After the crash, repaired game files in Steam and played 6 Gauntlet matches, after each reenacting the same things that could have triggered the crash. Nothing happened.

Fast forward to release of update 1.1.2.0, the crash is now occurring within 20-25 minutes. It can happen after having played a round of gauntlet and messing about in the menu or when I'm in the settings and messing about there for over 20 minutes without ever having gone into a Gauntlet round. Whatever that you've done (repairing game files, clearing shader cache, etc, etc) does nothing.

I haven't tried this fix personally but will give it a shot:

1. Disable PBO (not to be confused with disabling PBO limits, disable the PBO feature entirely)
2. Disable Core Performance Boost or CPB

It's a crapshoot but worth trying since it is not hard to undo if things don't work out. 

There is also a registry edit that can be done to the Timeout Detection & Recovery (TDR). It's a reaaaally old Reddit post. May or may not help. As always backup registry before making any changes.

Best of luck to you and the rest of us having this similar issue.

Hopefully someone chimes in with a concrete fix to our woes. Cheers.
