I am using RX 7600 for the last few weeks. I was getting roughly 90+ FPS with vsync on high settings(MSAA 4x) in my computer. But today when I opened the game. The fps dropped down significantly. Now I am having 70 fps on average. I tried turning off the vsync and reduced the usage of background apps but the problem is still there.Then I switched to MSAA 2x and I got 90+ fps. What can be the cause of this sudden fps drop in my game? And how can I get my previous in game fps while using MSAA 4x as before.
Note: I am using an AMD ryzen 5600G processor. I am also using the latest graphics card driver.
Thanks in advance.
