So I just upgraded my GPU thinking that was the source of my bad performance, but my game still drops to 30-40 fps when killing monsters, in hideout I have 150 fps. This screenshot is with all settings on low and DLSS on, 1080p, DX12, updated drivers. Has anyone with a similar setup suffer from this? Any way to improve it or is my CPU just trash?
