NVIDIA Image Quality

It´s time to see how NVIDIA GPUs enhance image quality. Let's start with our favorite Bunny, should we? Here is an image with IQ settings and DXVA mode off.

Now please have a look at the next image. Do you see any difference?

Yes sir, that's the DXVA ON NVIDIA GPU enhanced image. Do I see any difference? Well, I actually do. The first difference is the background color. The non-enhanced image looks a little bit red at the background, while the enhanced image looks more natural. Other than that, I can´t see any noticeable difference between the images. I repeated these tests 3 times in order to make sure IQ settings were enabled on the NVIDIA control panel, and they were. Grass looks the same, bunny looks the same, and basically everything is the same except for the red background color which is caused by enabling a wider color range on the NVIDIA control panel. How bad is this? Well, the difference isn´t noticeable enough. Most people wouldn´t have noticed the color range adjustment in the photos. Let's try the second video in order to see if we can find bigger differences this time.

Again, if you force your eyes, you will notice the red color is somewhat changed. Look at the house on the background and you will notice a colder red color. In general, the picture looks colder (color temperatures) but anything else is practically the same. Also, the girl´s face is a little bit brighter.
