Its really not (though I realize this varies for people). Other than adding the vsync=true to the ini to sync x/y mouse movement (which does nothing here), the other major EMUs require no tweaks. No core priority/affinity, no eqpn, no eq windows or other software, nothing. They just work.
This is literally the steps to play SoD:
1. Download EQ (you can even DL it legally from Sony. All EMUs require you to get your own copy of EQ, but some can't use installs that have been patched from live.)
2. Sign up for an SoD account
3. DL Patcher and delete the EQ live shortcut.
*Updating - the patcher handles any updates pushed out by the devs.
**EQ windows is a checkbox option that comes with SoD, but isn't required. Bind affinity is a checkbox in the patcher if you want to use it, but isn't required. SoD offers links to EQPN but isn't required and most people don't us it.
p99 install steps
1. Download EQ - Titanium only (don't patch to live or you have to start over.)
2. Download files and manually replace them in your titanium install
3. Delete files manually in your install directory
4. Sign up for 2 accounts (Forums/login)
5. make a shortcut for the launcher and delete the shortcut for that launches live.
*Updating - you have to manually download and install updates or you can't play after the devs release and update.
I honestly don't think it could get much easier to install an EMU than it is with SoD. It is seriously no brain easy, and it is much easier than installing the most popular EQ EMU. Most people install the thing and it just works no matter what windows OS they use or what graphics processors they have. (I believe you can even play SoD on Apple and Linux.)
In terms of game play: As said before, the current SoD client is old as shit and was put in production way before p99, which is why it has more bugs. The Devs are working to upgrade the client to a much more modern version than even P99 has. This will fix the most glaring client issues: Raid bug, keyboard bug, target ring bug (AMD), clipping plane bug (Intel), some custom UI stuff that you don't notice unless you are a power user, and hopefully the LD while zoning bug.
One thing that could be helpful to new guys is for YOU to work through your issues in tech help forums section. That way, new people who are unlucky enough to have your problem can seek help by searching and finding your post/solution. Also, if there is no configuration solution for your problem, the devs can look at it and maybe fix it.
