Performance issues in Overwatch

It's my first time trying linux so I installed CachyOs on my laptop. I tried playing overwatch via steam like I do on Windows 10 which runs at like 45 fps, my problem is that with the same config it runs at 15 fps on CachyOs. As a first-time linux user I wanted to know if there's a way to get better performance or that's just the way it is for me. Thankfully my laptop isn't my main gaming computer but wanted to give it a shot anyway.
