My BO6 settings that don't crash, for those willing to try anything

[Anim]

These are my no crash settings. This profile is optimised for multiplayer without distractions.

These settings push more work to the GPU and not the CPU.

So, if you are at your ends tether and have tried everything known to man. Then try these settings and see if it helps.

Note: The latest NVidia driver -> Optimise -> Max Performance profile setting causes the game to crash within 5 minutes for me. Don't trust its optimise feature. Try my custom setting above first and see how you get on.

Thank you! I appreciate it! Been losing my mind with directx errors. Will give it a try! Were you experiencing directx errors too?

[Anim]

I have had all sorts of errors and crashes because I was tinkering with settings and running benchmark after benchmark. In the end the above is my stable setup. However, not sure what effect this will have on DirectX errors to be honest. Those are windows system files which may need you to run SFC or DISM commands to check your OS.

Just an FYI for people who have also found this on google; this doesn’t resolve the direct x or hard crash issues.
