Deteriorated graphics. (Grand Theft Auto 5)

Once I reinstalled the OS because it was already littered. But before reinstallation I was playing gta on high textures without lag and freezes with a normal long rendering of textures, normal antialiasing, anisotropic filtering to 16x worked from the settings of the gta 5. After reinstalling the OS, on high textures already comes with friezes, anisotropic filtering only works from the Nvidia control panel, antialiasing is also barely working, textures are loaded when you approach objects (grass grows in front of me, 20 metres ahead of her if do not have and so with other objects: cars, people, etc.). Shadows and various objects sometimes flicker at certain angles. Played earlier and the troubles did not know. On my hardware the game in General was stable (GeForce 560 Ti, Intel r core i5-2400 cpu 3.10 ghz, RAM 8GB)

What is small black dots on the textures:

Here you can see how the texture progruzhat as you get closer to them:



On this screenshot you can see how behaves the grass (if its not):



Closer to the grass:



I tried to solve the problem but all to no purpose (re-installed Windows, drivers, tried to fix from the Nvidia control panel). Please help to solve the problem!
