*Sorry for bad English.
I have often seen the load window when move quickly around the world of Far Cry 4. Textures of the world simply do not have time to load. I had to wait for about a minute.
Next, I had a problem when I used the camera. My screen just goes black, but I continued to see labels that put. When I was removing the camera - everything becomes normal.
Just by pressing the " M" ( Quick menu ) - the screen goes black and goes a long loading of the menu (about 1.5 minutes).
By pressing "Esc" (Main menu) - same thing.
So what i did. I opened main Far Cry 4 folder, go to "data_win32", find "patch.dat" and "patch.fat" files and replased them to another directory (i put them to the desktop) (or you can simply delete them).
After all I sarted the game and was just happy.
No more freezes, no more stuttering, camera works fine, all menus load fast.
If it will help you please let me know.
Peace.
