AMD Driver Issues

Example of how these black flashes on AMD drivers look.

The issue you are experiencing with the black flashes across your screen is due to a newer version of AMD graphics drivers with poor support for the older DirectX 9 API. Unfortunately, AMD has chosen not to attempt to fix their implementation of Direct3D 9.

There are now two methods to rectify this issue. The first uses a Vulkan API wrapper to interpret calls to the Direct3D API. This method is the much more secure method, and may also increase performance on heavily CPU bound systems.

If this fails to fix the issue, then consider using the second method; however, please note that the second method disable Windows Update and rolls back your graphics card driver, which may open your computer to security vulnerabilities, so use method 2 at your own risk.

## Method 1 - Vulkan API wrapper

Note: you will need a third-party file archiver such as **7-Zip** (https://www.7-zip.org/) or **WinRAR** (https://www.rarlab.com/) to open the *tar.gz* file.

### Download DXVK

First, download the latest release of **DXVK** found here:

https://github.com/doitsujin/dxvk/releases (file is dxvk-*x.x.x*.tar.gz)

### Extract DLL file to game folder

In your file archiver, find the **d3d9.dll** file in the following location:

```
dxvk-*x.x.x*/x32/d3d9.dll

```

Copy this file to your game's base folder, which by default is:

**for 64-bit Windows:**

```
C:\Program Files (x86)\Utherverse Digital Inc\Red Light Center\

```

**for 32-bit Windows:**

```
C:\Program Files\Utherverse Digital Inc\Red Light Center\

```

### Run game

The game should now run without any graphical glitches.

## Method 2 - Rollback to older graphics driver

### Disable Windows 10 updates

The first step you need to take is disable windows 10 updates. This is due to windows otherwise automatically updating your AMD driver to the lastest.

You can do this using the Windows Update service. Via Control Panel > Administrative Tools, you can access Services.

In the Services window, scroll down to Windows Update and turn off the process.

To turn it off, right-click on the process, click on Properties and select Disabled. That will take care of Windows Updates not being installed on your machine.

### Uninstall Current Driver

If you have installed the older driver over the newer driver, you might run into compatibility issues. Therefore, we advise to first uninstall your newer driver. Instructions on how to uninstall AMD drivers can be found on their website:

#### Manual Uninstall

If that does not work please uninstall the drivers manually. You can read how to do that here:

### Install 14.4 Driver that still works with Utherverse

You would have to uninstall the latest graphics driver. And update to a older driver.
The older driver can be found here:
