Windows 10: cant open marvel rivals

i, I am trying to play marvel rivals on steam and it says "DirectX 12 is not supported on your system. Try running without the -dx12 or -d3d12 command line argument." I checked what DirectX I'm using and it says I'm using DirectX 12 so i wanted to know how i could fix it. i also changed the command line and nothing worked. I've restarted my laptop and checked for updates but nothing worked. the same thing is happening on my other laptop. im using a Yoga Pro 7 14IRH8

Marvell AVASTAR Bluetooth broken functionality

Hello Jeffrey,

I have done what you suggested a few times. Right now the Marvell Adapter appears to be 'behaving itself'. This was after I removed all the Bluetooth devices apart from the surface cover and ran the Surface diagnostic test for surface pro's. One thing
I notice is that when the adapter is 'playing up', I go to trouble-shooter and find that is "turning on the Bluetooth radio adapter" or that it installs the Marvel Avastar Bluetooth driver again.

You haven't really answered my question. Is there a problem with the Marvell Avastar Bluetooth drivers? Is Microsoft working with Marvell to fix this problem? Is the fact that the latest surface pro's have
Intel Bluetooth adapters an indication than Microsoft no longer trusts Marvell's adapters in the surface pro?

Marvell 91xx slow disk write

Gigabyte B75M-D3H motherboard
Windows 10 1803

Accessing the disks works fine.
But writing is at USB 2 speeds.

In Device Manager -> System Devices it is listed as Marvell 91xx Config Device.
The driver is latest (checked various ways.)

In Device Manager - Storage Controllers it is not listed.
DriverFinder shows it as not having a driver.

The Marvell Tray Utility seems to be happy with everything.

Just very slow write speed.

I have seen other post in the forum showing it as listed under Storage Controllers, so I was wondering ...
