Hello airtex,
I think I found the problem.
Actually the missing audio seemed a minor problem, but at the end that is the root cause.
I’ve a ROG Strix Wireless headset that works perfectly through a dedicated ASUS usb key to make them wireless.
If I connect the headset directly with a simple audio cable to the motherboard and I do not switch on the headset, then I get more than 260 fps!!!
Now the problem stays in how to make this headset working with BMS (or change it ).
Thanks you all for your support.
