I own a ASUS gaming laptop...

It has two flaws: One, it has nVidia Optimus (that just suck, whoever implemented it should be shot).

Two, the I/O is not that good, even with a 7200 RPM disk, and Windows 8.1 make it much worse (windows for some reason keep running his anti-virus, superfetch, and other disk intensive stuff ALL THE TIME).

This is noticeable when playing emulated games: games that use emulator, even cartridge ones, need to read from the disc/cartridge on the real hardware, on the computer they need to read from disc quite frequently, the frequent slowndowns, specially during cutscenes or map changes is very noticeable.

The funny thing is: I had old computers, with poorer CPU (this one has a i7) that could run those games much better. It seems even hardware manufacturers forget I/O




I can bet in your case it's not the disk I/O actually, unless you have some very strange emulator the file access should still go through the OS disk cache. VMware for example surely benefits from it. How many GB do you have on the machine? How much is still left free when you run the emulator and the other software you need?


I noticed it as disk i/o because I would leave task manager running on second screen and every time the game lagged memory and CPU use were below 30% and disk was 100%, and if I left sorting by disk usage, the first places are the windows stuff, and after them, the emulator.
