It seems most obvious to me in Insurgency, although I probably ought to run some kind of diag thing to pinpoint the problem.

The machine has 32GB RAM, Ryzen 9 3900X (not OCd), Radeon RX 9070 XT (slightly factory OCd), feeding a MSI 49" 5120x1440 display. In practice, I rarely get more than 100 fps at native resolution, often more like between 30 and 60. Looks nice though.
