I've recently swapped from a 4790k to a 2800x. Even when dedicating half the cores/threads to a single vm, I'm unable to get the frame rate for fortnite above 120fps. In heavy parts of the map, it struggles with 60fps. On native, these parts run at around 140fps and the rest around 250.
The gpu isn't hitting max utilization (around 30-50%) and I think it's being cpu bottlenecked, however cpu usage sits around 60% so I'm confused as to what is causing this lack of performance.
