The behavior of the processor and the video card in the game. (DayZ)

People, such a problem ... I have a gtx770 with Zovod overclocking (from a gigabyte) and an i5-2300. In the game, for some reason, the vidyuha works at 35% at the stock frequency (I watched the autoburner), and the percentage at 50-60%, while the percentage of 100% draws in the vidyuha, for example, in the Witcher 3, everything works at 90-100% (vidyuha jerks 99%, percent 85-99%). + noticed if you leave the city in the forest, the vidyuha starts working already at 45%, also at the stock frequency. Is it all for everyone, or is it just my glitch? What can you do about it?
PS I changed the configs and launch parameters, and no, they did not affect the load situation in any way, but 5-10 fps in the city increased.
