I took a break for 3 days after the act ended, I returned and got diamond 1 but I was playing so bad and I still am, I don’t know why either

I really don't understand why for the entirety of the time I've played valorant. knifing has always been bad. I can never recall a time it was good or useful. like, look at this clip as an example. https://reddit.com/link/p0urk1/video/ix1a...

Anyone knows how to make val more vibrant now since geforce doesnt support it? And also since im on a laptop i cant change the vibrance from the display settings.
