The video card in online games does not load 100%

I welcome everyone! Faced such a problem, the video card EXACTLY in online games does not load 100%, I tested it in games such as: Battlefield 1,3,4,5, call of duty warzone, gta online, world of tanks, war thunder, fortnite, battlefront 2 and many others. In all of these games, the video card is loaded by 40-70%, sometimes it shows 80%. Thanks to this, in online games, it shows FPS less than it should be. In games such as: Resident Evil 2 remake, 3 remake, Village, gta 5 (single company), metro exodus, the witcher 3, red dead redemption 2 and in other single games, the video card is loaded as it should, at 100%. The drivers are all updated to the latest version, the processor in combination with the video card is more than sufficient (you will find out the PC configuration below), no overheating was observed on either the video card or the processor. In programs such as AIDA64 and "BUBLIC", the processor and video card passed a long stress test for 20-30 minutes at 100% load, no reboots or crashes were observed. Windows has been updated and reinstalled on more than one occasion. Who knows what may be the reason, or who has come across the same, then please, respond. Thank you very much in advance!!!

MY PC CONFIGURATION:
CPU- intel core i5-10400f
GPU- Gigabyte gtx 1080 (bought in 2018 by me personally)
RAM- 16gb ddr4 2666MHz
