The ps2 has less power than the Switch yet it takes a very loving beefy pc just to emulate it smoothly. The switch is a hell of a lot more powerful than it, so that along with the software will make it hell to emulate at all
That's because the ps2 has completely different architecture to a PC. The switch has the same architecture as used by pc.
Xbox one and ps4 also have this pc architecture which makes them a lot less resource intensive once someone actually makes emulation software lol.
Though the switch could be super drm heavy and forget us all over regarding emulation, who knows
Also if you consider
Windows Vista / Windows 7 (32bit or 64bit) with the latest DirectX
CPU: Intel Core 2 Duo @ 3.2 GHz or better OR i3/i5/i7 @ 2,8 GHz or better OR AMD Phenom II @ 3,2 GHz or better
GPU: 8800gt or better (for Direct3D10 support)
RAM: 1GB on Linux/Windows XP, 2GB or more on Vista / Windows 7
a very loving beefy pc you might want to switch from windows 95 to at least windows 7 lol
