Fps lag - amd radeon settings

Hi,
I wanted to ask you for help regarding the FPS drops that I am experiencing lately, I have an i5 and an AMD Radeon HD 7800 GPU, I also have a 1ms -144hz gaming monitor, I must say that all my games run well and even CF until recently does. Could you by any chance help me with the settings of AMD RADEON? I also sent a ticket to support to try to fix the problem and stabilize my FPS as much as possible. I hope you can help me and I thank you in advance. Good day!
