I have now had success in getting the latest windows drivers running properly for my W5700X and can see a decent improvement in performance.
This will only work if you take the following steps (which differs in some parts to the video install guide on bootcampdrivers.com)
- Boot into safe mode
- Run DDU (as per the bootcampdrivers.com install video) 3 times. After the third time, restart.
- Boot back into windows normally, and install the *official Apple bootcamp drivers*, via the setup file. Do not restart your computer.
- Download bootcampdrivers.com August Red drivers, use 7Zip to extract them to a folder and call that folder ‘Red’.
- Without restarting, go to Device Manager and under Display, right click on your graphics card (It should be identified as W5700X now), and click update driver. Search for drivers manually, and point it towards the folder ‘Red’. Keep the option ‘search within subfolders’ ticked. It should update the driver.
- After this is done, before finally restarting, run the setup.exe from the folder ‘Red’, and make sure ‘Factory Reset’ is NOT checked.
The above steps should get the drivers installed and a notable performance increase. I still have an issue with the Adrenalin software crashing but this does not affect in any way the stability of the driver, or impact performance.
