Can someone help me, please? A few years ago I played Witcher 2 on my current computer, and at that time I was able to play with about medium settings without any lagging. But now, after I reinstall the game, I have to set all settings to the lowest, and even so the game is not fluent enough. (The power plan is set to high performance and I'm running the game with the nVidia card, not the integrated one.) The only change since then, that the Windows 7 has been upgraded to 10.

Hi there! Try to find 1.3 version of the game. Helped me a lot.
