If you are following the steps here without being in touch with the support team, you can figure out the devices in your system by running the dxdiag tool. To run this, just press the Windows start button on the keyboard, enter dxdiag, and select to run the command:
The "DirectX Diagnostic Tool" window should appear and look something like this:
...
On the next dialog, select to RESTART NOW to reboot the machine and completely remove the remains of the driver.
Uninstalling this component should also implicitly remove the other components like HD AUdio Driver and PhysX System Software.
After the deinstallation, restart the machine again.
As pointed out above already for the AMD case, Windows might install default drivers now for the NVIDIA graphics device. Just let that process finish up and afterwards verify that the NVIDIA Graphics Driver entry in the Apps & features settings is gone.
Remove Intel graphics card drivers
If you happen to have an Intel graphics device installed, make sure to uninstall the current drivers for that device as well.
Install the latest drivers for the graphics devices
After the uninstallation of old drivers, you need to install the latest drivers.
If you have multiple graphics devices in your system, we recommend to install the drivers for the integrated device first and for a dedicated device afterwards. For instance if you have an AMD CPU in your machine with an integrated VEGA graphics device, install the corresponding driver for that first.
Latest drivers for AMD and NVIDIA graphics devices can be downloaded on the following pages. For completeness we also list the driver download page for Intel integrated graphics devices here. Bare in mind that the game however officially only supports dedicated graphic devices. You might be lucky to run the game on an integrated chipset, but neither can we ensure this, nor are we able to provide support if the game doesn't run on such a device, even after having installed the latest drivers.
Installing AMD drivers
On the download page select the device installed in your system (as you noted down in the first step).
For instance, if you have an AMD Radeon RX 5700 XT graphics card, select: Graphics -> AMD Radeon 5700 Series -> AMD Radeon RX 5700 Series -> AMD Radeon RX 5700 XT -> SUBMIT
If you have an AMD Ryzen 5 3550H with an integrated Vega graphics device instead, select: Processors with graphics -> AMD Ryzen Processors -> AMD Ryzen 5 Mobile Processors with Radeon Vega Graphics -> AMD Ryzen 5 3550H -> SUBMIT
On the next page you need to select the correct Operation system (usually this will be Windows 10 - 64-Bit Edition nowadays) and then the driver package you want to install. In general we recommend to go with the Recommended driver in the list which is also WHQL certificated. However, you can also go with the Optional version, if you want to give that one a try instead. Click on download and then execute the driver installation.
On the following screens just go through the steps pointed out by the installer. If there is an option to select to perform a clean installation do select this option and make sure that you 
DO NOT deselect the Vulkan Runtime package.
After the installation went through, restart the machine.
If in addition to the AMD graphics device you also have a dedicated NVIDIA graphics device installed in your system, follow the steps in the next section (Installing NVIDIA drivers) next. If the AMD device is the only graphics device in your system, you are done now and hope fully the game runs without problems for you again.
Installing NVIDIA drivers
On the download page select the device installed in your system (as you noted down in the first step).
For instance, if you have an NVIDIA GeForce GTX 1080 in your system select:
- Product Type: GeForce
- product Series: GeForce 10 Series
- Product: GeForce GTX 1080
- Operating System: Your operating system (usually: Windows 10 64-bit nowadays)
- Download Type: Game Ready Driver (GRD)
- Language: The language you want
Click on Search to get a list of the latest drivers for the combination.
On the next page, click the download button (confirm it once more by clicking Download on the next page again) and run the installer.
Windows is likely to ask for confirmation to run the installer. Just click on YES in the dialog.
Next you will have to select a location to extract the installer files to. Go with the default and click on OK.
A progress window will appear.
Wait until the process completed. Once done, the actual installer will start and initiates the system check:
Once that is completed, you can decide whether to install just the plain drivers or the drivers and the GeForce Experience package.Chose whatever you prefer and click on AGREE AND CONTINUE.
In the next dialog select Custom (Advanced) and click on NEXT.
In the following dialog all components should be selected. In addition to this, make sure to tick the option Perform a clean installation before clicking on NEXT again. Note: This option will reset any configuration/settings you might have done on your system. However since you are doing the reinstallation of the graphics device drivers to fix some issue with the previous installation, setting this option is HIGHLY RECOMMENDED. If you decide not to select it, feel free to give it a try without setting this option. If you have still trouble getting the game to start afterwards, we strongly suggest to follow the clean reinstallation instructions on this page a second time but then enable this setting here.
The installer will now install all components and your graphics device is likely be reset once (with your monitors going black for a few seconds). So don't be afraid, if this happens.
After the installation completed, you can adjust the settings on the final dialog to whatever you prefer before clicking on CLOSE.
Once done, please restart the machine. You should be all good now to start the game.
