Stutter when loading textures

[stormye]

I have this issue for a while.Game stutters when loading new textures,mostly on start of a game and when flicking around a new places where game didnt render yet or when there is alot of players around me.Also there is some render delay similar on this short video i recorded and you can see frimetime jumps for milisecond that cause stutter and its rly annoying knowing my system could run this perfectly 60+ fps since i play on very low settings.I didnt notice any of streamers have this issue so i think its not game problem,same with pubg and other games.Can record some gameplay and provide more info if you need it.Did most of things i could think of.Game and Win are on ssd.
SYSTEM:
Video Card:Radeon RX 580 8 gb Aorus
CPU:Ryzen 7 1700 3.0 GHZ
RAM:2x8 Hyper x 2666 MHz 16-18-18-39
PSU:Corsair CX650M (not green)
Motherboard:Gigabyte ab350m gaming 3
SSD:Adata su800 256 gb
HDD:1 TB Barracuda Seagate 7200 rpm
User benchmark was fine (cpu bit underperform 42th but i think its because most ppl overclock r7 1700 and mine is stock 3.0)

Any help would be greatly appreciated!

Ram speed is kinda low, for a Ryzen rig, and an overclock wouldn't hurt. Is your bios up to date, on that motherboard?
