Problem with the picture quality

No matter what graphics settings I set, the image quality doesn't change. The picture is pixelated, the lighting has changed slightly to brighter. FPS drops when driving on gravel (it didn't happen before), in other games everything is fine

I noticed that the discrete graphics card does not use resources for the game at all (except for video memory), the game runs on GTX 1060, I turned off the graphics core of the CPU.

I tried reinstalling the game, installing previous drivers, changing settings in the game, but nothing helped. I even set everywhere to force the use of GTX 1060, but the game still uses it, but at 1-0%.

Video card: GTX 1060 3gb
Processor: Core i5 8500
16 GB
