Windows freezing with BF5 and BF1 with Sound Blaster Audigy Rx/5 audio card
A few minutes after launching BF1 or BF5, the game and windows begin to respond very slowly to mouse and keyboard input (less than once per second), and there is a constant beep from the audio output...
Fixed it seems.
I has Rx sound card too, previously uninstalling audio driver fixed crashing.
Either EA updated, or I turned off Core Isolation, and it worked it seems as I am playing right now.
