Our how to is only an example of how to edit these files, it shouldn't matter what type of graphics card you have. It works regardless of if you have AMD or Nvidia. We have Nvidia graphics cards so that is what we used for our example.
The files in the zipped file attached should work for you. Download and unzip. You can overwrite the current .sgr files with these.
