I'm late to this thread, but I don't see anything "speedy" about the Kingston update.  It takes as long to initialize Sonar as it has on previous versions.  Same way loading a project.

for sake of balance, I find Kingston to be a lot quicker in initialising Sonar and opening projects.
 
As an example, my Orchestral Template which is an absolute beast used to take approx 8 minutes to fully open.
 
It's now less than 2

I think that may also be dependent on VSTis used. IIRC, a chunk of the speed came from ins/outs with multi-timbral synths. These are not something I use often, so have not seen much "speed" either.

I don't see any performance issues at all really whilst using Sonar, but I agree with you about startup/project loading (and the start screen as well) being optimized. Could also do with some sort of 'please wait' visual display/buffering animation.

I don't have any problem with PC resources and Sonar is installed on the SSD OS disc.  Just does not appear to be any faster than previous versions either in initialization or use.

Just wanted to update on my Sylenth1 situation - the most recent update for Kingston fixed my loud white noise/distorted playback. While it was initially annoying that the synth didn't work, I've gotta say that it's very awesome that a fix was dispatched so quickly after the problem was reported! Kudos to the dev team.

Kingston Update 1 now available:

I can confirm that Kingston Update 1 fixes the 64-bit Engine problem with Sylenth1, Poly-Ana, and V-Station VST2 on my machine. Thank you!

Cakewalk - top job!!!

FYI. I did a VST reset and rescan. It got quite wobbly - error messages everywhere. Rebooted - all works now. Not sure if this is system specific or not, let's just say it is right now until somebody else chimes in.
