If Nvidia can use either one those 2 then Read Framebuffers To Memory(GPU) needs to go, or am i missing something? Or maybe some games have different issues with those 2 options?

We really need an updated readme explaining all this because the PPSSPP options explained thread is out of date.

The Read to Framebuffers (GPU) options offers a faster rendering method for NVIDIA cards afaik for this game (or any other games that need this option to be enabled), which is why the option is still there.

AMD, Intel and Android devices (like PowerVR and Adreno chipsets) have to use Read to Framebuffers (CPU) for proper functionality in games that need the option enabled. This is also slower than the above method, but required for non NVIDIA cards since they lack the proper support in their drivers.

The bottomline is that, if you have an NVIDIA card, you have a faster choice, that is all there is to it. If there weren't any speed benefits, the option would have indeed, been made redundant, and removed.

(Which is the case in Android builds, if you've downloaded one of those, you'll notice that the Read to Framebuffers (GPU) option has been hidden, since it serves no purpose there)
