Why my screen graphics becomes shoppy or laggy when I play Valorant?

I'm using a laptop model Acer Nitro 5 an515-42 (AMD Radeon RX 560 and AMD Radeon Vega 8)

Here are my specs:

Processor : AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx 2.00 GHz

Installed RAM : 8.00 GB (6.90 GB usable)

System type 64-bit operating system, x64-based processor

When I play Valorant, I play it under AMD Software : Adrenaline Edition and set under AMD Radeon RX 560 graphic series.

However, for some reason, the screen becomes laggy and choppy. It hinders my gaming performance as I can't shoot properly, not to mention the loading screen is also quite long. I'm not sure why.

I've tried to lower the video setting and choose the lowest graphic performance.

I also have done every possible AMD software updates and remove other unnecessary running background apps but the problem still occurred.

I'm using Internet with 300mbps so my ping was okay (maintaining 30 pings and below).

Is there anything that can be done?
