Results: Grid 2
We haven’t been benchmarking with Grid 2 long enough to know for certain whether the title is CPU- or memory-limited. But you probably don't care at this point; bottlenecks that happen up in the 150 FPS range are hardly detrimental to an enjoyable racing experience. But because these average frame rates show up in our performance-per-dollar calculation, they do matter.
It looks like we push past those bottlenecks using the Ultra preset at 4800x900 and higher.
