→Emulation issues
There are two major bottlenecks at play:
* '''Cell.''' It consists of two architectures that developers have to program for; PowerPC, and... whatever the SPEs really are. Add to that the fact that there are SIX that could be in use by a game, and you have a great formula for high system requirements. The RPCS3 developers technically cheat by using ahead-of-time recompilation using LLVM, but because the emulator constantly improves, that can be easily excused.
* '''[[wikipedia:RSX_Reality_Synthesizer|RSX Reality Synthesizer]].''' The [[Xbox emulators|Xbox]] also went unemulated for a long time, simply because of how many components were just undocumented. The same thing applies here; the graphics card is Nvidia GeForce 7800 GTX-based, which means it's not well-documented and developers have to figure out how it displays graphics and graphical effects. Without access to Nvidia's resources, which would normally be included with an SDK, this would be very difficult.
:Something of note is that this GPU was also managed by two different memory units with very disparate frequency speeds; 1) 256 MB of GDDR3 RAM clocked at 650 MHz with an effective transmission rate of 1.4 GHz, and 2) up to 224 MB of the 3.2 GHz XDR main memory via the CPU (480 MB max).
