SmartElfo: Hello everyone.

I have start playing the game and almost immediately encounter a problem with camera. The camera has glitched in some strange way which made impossible to control the main character.

I also noticed that my video adapter became very noisy, which is strange for such an old game. It is normal for new games, especially games which are using Unreal engine, but it is very strange for such an old game

So I went to graphics options and I noticed that VSync option was turned off by default. I have turned it on and this have solved my problem. The VSync option is hard to recognize because of an "old notepad" style of the menu. But it there, right below the "Gamma" option.

Now I believe that this solution worked for me because I have 60Hz monitor. So by turning on the VSync I just caped game's refresh rate to 60FPS. But this solution might not work for people who have 144Hz monitors.
So if you have a monitor which is more than 60Hz, I guess you can just cap the refresh frame rate through NVidia control panel or a similar control panel for ATi Radeon adapters.

To cap the refesh frame rate for NVidia adapters. Open the NVidia control panel "Click on NVidia setting icon in system tray". Then select "Manage 3D settings" on the left tree view menu. On the right side select the "Program Settings" tab. Click on dropdown list search and select the game. If the game is not in list, click the "Add" button, if you still can't see the game, click on "Browse" button enter your game instalation folder and select the executable file.
After adding game to a list, look for the "Max Frame Rate" option in the option list. Select this option and set it to 60 or even 50. Start the game and the camera glitch error should be solved.

Sorry ATi Radeon users I'm not familiar with ATi control panel so you have to search for such an option by yourself.

I hope my solution will help someone.

Overall I liked the game. It is a welmade stealth action game with very interesting game mechanics.
