Hi, I have read it carefully and even our IT guy tried his best. Unfortunately there is no gpu_table.txt on my Bootcam (MacBook Pro Retina with Windows 8.1) anywhere (incl. AppData\Roaming). I have checked all suggested locations, switched to see both hidden and system folders/files, searched whole Bootcamp partition, but it is just not there... Thus I do expect that the guys here probably used previous version of Windows. Hopefully someone can help...

... I am using Windows 8.1...

Dear Tomos, I tried to use your hint, but unfortunately did not find gpu_table.txt anywhere on the computer. Could you please help? Thank you. Best regards, Petr
