Windows – Battlefield 2 via CrossOver: Graphic Bug With High Terrain

I had that exact same problem. I don't have an easy fix for it but what I did was just keep retrying and it eventually made it to 100% and worked fine.

Step 1: Download the most recent Cirrus Logic drivers from the Cirrus Logic page. The CS4207 driver is actually more appropriately named "CS42**" driver.

--> go to this page: Here

--> click the "Resources" tab

--> in the "Resources" tab, under the "Tools & Software" heading, select the appropriate driver ZIP file for your particular configuration. Since I am operating in Windows 7 64 bit, I chose the "CS4207 Windows Vista (32/64-bit) and Windows 7 (32/64-bit) Driver, 8/2010, v6.6001.1.26 : 100 KB"

--> download the file to your desktop

--> create a folder on your desktop called CS4207 Drivers (the name doesn't actually matter)

--> move the downloaded ZIP file to this new folder

--> expand the ZIP file within this new folder

Step 2. Go to Control Panel, Device Manager.

Step 3. In Device Manager, open up the "Sound, vide and game controllers" sub menu.

Step 4. If you're like me, you had 4 NVIDIA High Definition Audio entries, and one Cirrus or Intel entry. Click on the Cirrus or Intel entry for the Sound controller. Uninstall the driver and, if it gives you the option to delete the driver files used, do so.

Step 5: Go back to Device Manager, and select "Scan for hardware changes" from the right click dropdown menu.

Step 6. Let your system automatically install whatever driver it wants.

Step 7. Select that new driver entry in Device Manager; right click the entry to update the driver; choose the Browse option, then the Let Me Pick option; and then select the new folder on your desktop as the driver location.
