Abnormal Lag

[Ruler]

I have 60-90FPS, my latency is  40-300 (150 average) and sometimes I'm getting extreme lag. It feels like I'm teleporting, when I'm driving my car seems to drive straights down the road then it teleports and hits the wall, cooking nades is delayed af, sometimes im having ghost shots, sometimes it shows that my bullet hits both the wall and the target, usually shooting directly at target doesn't even land a hit. I'd assume it's my own latency issue but I've played on far worse latency on my old pc and it wasn't that bad, plus high latency would only mean delayed response time and not teleporting or stuttering. I have no idea what's wrong, my laptop specs are good and it's definitely not the problem that causes all this lag. Any suggestions?
