X3e is fabulous so I am not sure it can be beat in this department.  But out of curiosity, is anyone experiencing the ability to lower latency for the same project by going to Platinum?

I have a fairly fast computer and an RME interface, so I usually stay at 48 samples ASIO buffer up until the absolute mixing endgame. This worked well for me in X3 but Platinum for me feels even snappier and more solid! I feel SONAR has gotten incrementally smoother and more responsive (more "gapless" if you will) at low latencies with every update the last several versions.

I was slightly worried about this as I only have a 1.6GHz i7 laptop.
 
Presumably we still have the option of running X3e if Platinum seems to cry out for a new machine?
 
Thanks!

Yes. X3 will still run as normal if you didn't uninstall it prior to the Platinum upgrade.

OK thanks. Presumably it still holds true that we shouldn't uninstall old versions? I did that last year and had to spend a week reinstalling Windows and all my music stuff :-(

There shouldn't be any difference in latency. Its really a function of the audio driver and audio interface.

I have the same latency in both X3 and Platinum. 

I posted about this a few days ago.  I'm not sure if it's a coincidence or not, but after installing Platinum I'm able to run my Behringer 1204USB interface at 48K/96 samples.  Overall RTL = 7.9.
 
With X3e I couldn't get anywhere near this.  I had even gone back to my Delta66 while researching new interfaces.
 
It's possible that a Windows update somewhere in between made the difference, but the 1204USB driver is definitely the same.
 
I'm still looking for an interface with more I/Os on the USB side and some HI-Z inputs, but the pressure is off.  I'm actually having a hard time nailing down any real-world examples of performance in the price range I'm interested in.

Apparently there are performance improvements, quite what they are remains a mystery, we will get a change log soon hopefully.

Any performance improvements can make a difference to latency, since low latency performance is directly a function of how long it takes to process a buffer of audio. i.e. if we improved a section of code that requires it to take less CPU it will potentially improve low latency performance.
 
There were numerous tweaks to the effects processing code in Platinum and some extensive work to reduce dropouts caused by disk access contentions. And we switched to the latest compiler than has some improvements to code optimizations. All these could yield benefits to low latency performance.
