After the update that introduced the Sam Fisher special operation, my game started to load terrain really slow and having 1-4 second long lag spikes every 5 seconds if going fast with a vehicle and sometimes when I ended up somewhere, roads and other terrain were low resolution texture mess and I had to wait several seconds for it to load the terrain.
Something changed to the worse. Everything worked fine before without any texture loss or terrain load problems, and I have GTX 1070 so it should run well.
And the lag spikes aren't like freezing the screen, it works like that if you use a car, you drive it and when the lag spike hits, your car is "driving" but not moving forward for a moment, freezing any living movement in the world but car keeps going on while in place. Makes moving in the world almost unplayable.
