Super 57ppd Requires Extra Processing Power ?

To achieve the same FPS in a Race or Flight Sim, using the same cpu & gpu, as the Super 50 ppd would require ?

I know the Super 50 ppd and the Super Ultrawide will perform 1:1 on the same hardware specs PC at same resolution.

So it boils down to, does the higher 57 ppd mean you will lose some FPS at the same resolution on same hardware ?

I cannot find this answered anywhere in all the Pimax blogs & videos. I had assumed there is no difference because it is just the different lens design that delivers the 57 ppd. However I would like the definitive answer on this, which could affect my decision to stay with my 57ppd order or change to 50ppd or Ultrawide.
