Pokud z toho nebude nic fungovat, pak jsem našel toto:

I think I found a solution. (Worked for me)

1. Download MSI Afterburner here http://event.msi.com/vga/afterburner/download.htm

2. Install it and run it.
3. In the "menu" there is a "power limit" slider.
4. Usually it's on 100%.
5. Run Crysis 3 on MAXIMUM detail and resolution, AA, Vsync etc.
6. Play for about a minute then shut it down.
7. Open MSI Afterburner and look at the top graph on the right side of the window (Power%).
8. If your card consumes about 100% power, then put the slider to 70 - 80%.
9. That's all! This limitation prevents Nvidia BOOST - does not undervolt. core.

Hope it was useful. ;)
