If you want PUBG to run fast but you still want a nicer looking game, there are a few options.
You can either use ReShade, which will allow you to add some saturation to the colors and some sharpening at the cost of a few FPS, or you can use Nvidia’s Digital Vibrance.
Nvidia’s digital vibrance will make the colors on your screen “pop”, improving the looks of PUBG, but also giving you an advantage when it comes to spotting enemies: with digital vibrance, the perceived contrast between say, a field of grass and a player will be higher. That’s why streamers like DrDisRespect use it.
Note that using the Nvidia digital vibrance setting will add more color to everything that appears on your screen, even Windows. So, if you just want your game to pop, you should go with ReShade instead (which is what summit1g does).
Also, obviously, you can only do this if you have an Nvidia graphics card with the Nvidia control panel installed.
Cool? Let’s move on..
How to Use Nvidia’s Digital Vibrance with PUBG
It’s super easy to turn on Digital Vibrance in the NVIDIA Control Panel. All you have to do is right click anywhere on your Windows desktop and select the “NVIDIA Control Panel”.
When there, under “Adjust desktop color settings” you simply adjust the “Digital vibrance” slider. A setting of + 75% works well in keeping everything “natural” looking while improving colorfulness and contrast IMO. But test it out and see what value works best with your monitor.
