Any chart for the GPUs running the game at 720p? My card can't run the game more than 38fps at that resolution (1080p).
those benchmarks are just meant to be a comparison. ultimately you're best off tweaking on your own
I don't have the beta yet, but I hear it has built in up/downscaling, so I would use that if you drop the resolution (it's probably better than however else you would upscale it)
the cpu benchmark shows how limiting the cpu is in this game. that can be frustrating because often no amount of graphics tweaking will affect your performance when your cpu is being bottlenecked
reading around, a lot of people, some with some pretty serious hardware, are getting bad performance. so I wouldn't stress it too much yet
