1080p/60 easily with a few setting adjustments.I turned off dynamic optimization and tweaking settings manually.
Motion blur = off, Shadows = medium, AA = 2X w/ FXAA, 8X Anisotropic filtering and the rest are all high. I play in the far chase camera so some of the settings like rare view mirror quality etc don't have any effect. I notice a few drops to mid 50's when there's a bunch of cars in areas with a lot of breakable objects (mostly starts of circuit races in urban areas) but it stablizes to 60 FPS within a few seconds, 99% of the times the games' running at locked 60.
