I saw this on youtube Pie in the Sky Tours. I thought here we go with another bogus tutorial that ends up wasting hours of my time…
I downloaded the NIS scaler and did the basic settings described.
I actually could see a difference! Using the CTRL- F1 key combination allows you to turn on / off the scaler instantly. It makes it easy to see the difference. Here is the video link.
Hopefully someone can make use of it also.
