Thinking of buying apple thunderbolt monitor. Has anyone done a comparison of performance with and without external monitor? Thanks!

Reduce the fps on what?

FPS on anything. Does it tax the GPU to drive a larger monitor? I've seen post regarding the macbook pro fan being on all the time when connected to a thunderbolt display. I'm curious if anybody has looked at FPS or scores with a macbook pro with and without a connection to the mac thunderbolt display.

Thanks!

Fan will more likely be on because external display can only be driven by dedicated gpu with how the MBP's are wired internally, integrated cpu is only connected to internal display. As to FPS, something running at the same resolution/complexity should be around the same, perhaps very slightly impacted by a little less VRAM being available due to the extra framebuffers needed for the external display. But something running at native resolution of external display will likely be worse, as resolution is likely higher.
