The solution to the problem of low productivity (Assassin's Creed: Unity)

Everything described below might help those who have a low in-game performance, drawdown fps, friezes. My system is Phenom ii X4 955 3.2 Ghz ; Nvidia 660ti. RAM 16гиг.

UPDATED

Below is the screenshot in one pretty loaded moment (Screenshots are clickable)

As you can see, the game gives out 17 fps, CPU load is around 70%, the memory used 1700 MB.

That's what happened:


~31 in a very loaded scene, since now the game uses 100% CPU. Freely moving around in the area of 35-50 fps.
The reason of freezes and unstable fps from the owners of graphics cards with 2gb of memory:
The game download when I click to continue(or new), loads the memory up to a certain amount(~1900mb), then part progruzheno it abruptly goes into the RAM and stays there. Consequently, depending on the number of departed in it, and this value may vary from 100 to 400 MB, you get lower performance(also varies), subsidence, friezes, and so on.
P. S. This method will help those who have system-level, better or slightly worse than mine, but even so capable of delivering the normal amount of fps.
1) Install the msi afterburner tool for measuring memory usage
2) be Sure to include the paging file in Windows, it is desirable to set a fixed size for min and max in the amount of 6500 - 7000 mb
3) Restart the computer (creating the swap file)

Further, the method is relevant for Nvidia graphics cards, Radeon Pro can not say anything.
You will need the tool Primo Ramdisk or analogues.

Resetting textures from VRAM in online in this game, due to several factors:
1) the Curvature of the engine.
2) Large amount of RAM installed in your system.
How is it interconnected?
If there is insufficient video memory in windows provides the ability to unload it, transferring some of the information online. And the more you free RAM, the more video card available capacity for discharge.
In this game it is implemented so that when approaching the peak value of the load of VRAM, the game automatically resets ~ 300mb in RAM, thereby maintaining a comfortable ~1700 amount of 2gb graphics card.
Users with a large amount of free RAM will this happen every time, and the game will slow down and so on.
Program Primo Ramdisk is able to create an analogue of the physical disk in RAM. The disc itself we are not important, it is important that when it is created, the system reserves RAM under it is equal to its volume. That is, when loading the game will think that you don't have the extra RAM and won't fold extra texture.
So on my system with 16gb of RAM I created a disk of 10.2 gb, thereby making the 5.8 gb free.
Before with minimal textures the game randomly dropping part of the texture in RAM and had to restart the game again to normal load. Now I can play with high textures are loaded almost all 2gb VRAM, no fps drops and so on.
P. P. S the Disk is removed and creates two clicks, even pc don't have to reboot.

Like AMD, you can manually lower the maximum amount of RAM available for the graphics card when memory is low. This is done in the tool Ati Tray Tools in the settings for OpenGL.

At long exposure of the game in the collapsed state, or after the death of the character and re-loading the level may be reset to RAM. So again not to reenter the game try not to die +))
