Hi xphen0m,
Sorry to hear that you’ve had some problems with your 2i2.
The performance you get using ASIO4ALL is not always a great benchmark to test against. ASIO4ALL is essentially a driver ‘wrapper’ in that it takes WDM (non-ASIO) drivers and makes them appear as ASIO drivers so that they can be used in a DAW. These drivers are typically 16-bit rather than 24-bit.
In your first post you mentioned that you were using an ‘800ms’ buffer setting in ASIO4ALL - if this was indeed the case then this would go a long way to accounting for why the VST Performance meter wasn’t peaking anywhere near as much as when using the Focusrite 2.5.1 driver at a 10ms buffer size.
As you’ve noted, you would appear to be using quite a few CPU-intensive VST plugins which may require you to raise the buffer size to avoid CPU overloads on your machine. You mentioned that you’d had some improvements since going to beta driver 3.2.2 which is great news, you may wish to try a slightly older alternative in driver 3.1.10: http://beta.focusrite.com/file.php?id=1154
Different drivers respond better/worse in different systems since there are a large number of other processes/drivers that are involved in the audio stack and they all need to work well together.
