Audio Interface Performance important for VST performance?

[Sternenlicht]

Can somebody confirm me if they also experience a massive increase of omnisphere 2 real time computing consumption in comparison to the version 1 of omnisphere?

With version 1 of the vst, i could run about 10 instances without any problem on my i7 2600k cpu. With version 2 i get 100% load on ableton with a single instance, with patches like "analogue ..." (new edm patches) , the baseline is there around 60% cpu load, when i start to run the orb from the vst, i easily get 100% load.
It does not happen on all the patches, a lot of the more simpler patches get only 8-10% cpu load, which i would consider normal.

Can someone help me understand the relationship between audio interface and VST performance ? Is there any ? Are the VST's performance only related to CPU processing speed?

[beats me]

Wouldn’t be surprised. I think some developers proudly wear the “CPU hog” badge.

idk

I have an i5-4690 and I dont have any issues. Sometimes the more convoluted patches take a while to load but I have never hit 100% cpu load.
But I never try to run 10 instances of omnisphere either lol.

I only run 3 or 4 at a time, or Ill use the multi function; once I find something I like I freeze it and move on..

Something sounds seriously wrong if your'e hitting 100% with one patch of analog....

The i5 is like 10% percent faster, and i did not overclock my cpu yet, allthough i have water cooling in place. Can you specifiy your audio interface? Does the audio interface have an impact on VST performance?

...it's a combination of interface and buffersize but mainly the buffersize...the higher you select the buffer the more plugins you're able to use...

Oh ya, this is spot on..

I have the presonus audio box i2 and to save cpu I try to run with a buffer rate of 1024 when im simply mouse producing, but if I need to record in real time ill drop it down to
256.

The RME Babyface is on my (rather large) wishlist; )

I am not overclocked either

It has everything to do with your interface and subsequently your buffer rate.
