I found some frame rate issues with the objective waypoint, some areas in the camera systems, and experienced it in some hallways in the main warehouse area.

I personally feel like it has to do with some of the effects put into the game, such as some lighting systems, and the particle effect produced by the waypoint.

I like how well this game is presently made and hopefully look forward to some options in the settings where these things can be reduced through the settings menu to help mitigate the lag issue.
