Pretty much the same problem with this thread but it was closed before I could get an answer. I would like to know how to fix or at least detect the problem which I have been struggling with over 2 years. Here is my comment:
Hey, I have pretty much the same problem thanks to you I changed tRC and it improved a lot. My pc is:
Asus X570 Croshair Hero Non-Wifi
Asus Strix OC 3090
Ryzen 5900x
32GB Trident z neo ram with 2 pairs of F4-3600C16D-16GTZNC
Corsair 4000x Case with H100x 240 cooler
I play Apex capped at 220 with 280hz monitor and it feels like 40 fps even tho it's pretty much locked at 220. It even gets worse over time when shooting and looting again the fps is at 220.
Have you find anything else to fix this problem? I'm certain audio is related to this problem because lowering it helps a little I think and it cuts off some sounds when other sounds are present.
I also had 5600x with Gigabyte B550 Aorus Elite and some other ram and the problem was completely non-existent at first but would become even worse after a few matches.
I must add my dogshit MSI laptop that overheats all thetime with Intel processor played better than any of AMD trash.
