As the title says, I am suffering terrible FPS drops on TF2 when players are on screen. As I understand, TF2 is a CPU intensive game, and I have an AMD Ryzen 7 3700X, a more than capable CPU. Even with all settings on low (maxframes configs and the like), my framerate falls to around 40-50 when players are on screen. Inversely, it maxxes out at my cap (144) when i'm staring at a wall or the ground, or in offline mode. I can't for the life of me figure out why this is - only a couple weeks ago I was getting 144 frames absolutely consistently, as I have been for the past three years. Any help appreciated, no clue what has caused this. Task manager says everything is normal - is it bottlenecking?
