Couple years ago I got into emulators super hard. Nowadays I have a laptop with an i7 in it but years ago I had a Pentium M. During that time it was amazing that I could even play snes on my laptop. When I found out about PS2 emulators my PS2 was dead and it was the only thing I wanted to play. Ever. Even still I will probably have a specific TV only for my current PS2.
When I first was researching it I wanted to know if it were possible to have a PS2 emulator on a laptop. At the time I know I had hardware that could barely run pentium 4 age stuff (but a pentium M is a pentium 3 so knowing that later makes that shit sensible) and I knew that SNES emulators were probably the top of the belt for me at that point. What I read up basically told me that at the initial release of PS2ALPHA you would need a high clock xeon (3.6 ghz I believe was the number) at minimum to get on par with the emulation standards. Otherwise you would have a massive glitchfest.
Its now..... 10 or 12 years later? Maybe 8 - 10? So at THIS point, with an i7 4510U, would it be feasible to have maybe even a PS3 emulator on my laptop? PS2 emulator would be fine enough.
