At some point, I briefly tried to migrate into a completely Linux setup. But eventually, I decided to switch back to Windows. The lack of games (or at least, the games that matter to me) really hurts, on top of already being a difficult OS for school productivity. Although I might be able to try it again once I have a lot of spare time available.
As for running it without sounds... yeah, I don't want to go in there. But here's one thing I tried. In the sound config files, I linked all the entries to play a silent ogg file so I had control which sounds would be there and which sounds would be silent. Basically, I silenced all sounds except for the combat sounds (which is really the only reason I can't play without sounds) I don't know if what I did helps, really.
I think I've said it already, but I'll say it again.
The laptop in question is a Mid-2011 11" Macbook Air running bootcamp.
It houses a 2nd gen Intel I5 processor, gets by with integrated graphics,
runs on 2 GB of DDR2 RAM, as well as a 64 GB SSD storage (24 GB remaining free space)
Oh, it also uses a 32-bit Windows 7.
