Hello
I tested Cubase 9.5 with 64bit versus 32bit processing precision and also version 9.0.30.
Seems there isn’t noticeable performance difference between 32bit engines.
Big suprise is 64bit audio engine. It outperforms all the 32bit versions?!
TEST 1:
Bunch of Sylenth, Massive, Addictive keys and Kontakt tracks. No insert/send effects.
Cubase 9.5 on 64bit engine outperforms it’s 32bit version and 9.0.30 version by small amount but it’s there.
TEST 2
Audio tracks with bunch of Krammer Tapes plugin on insert channel, Verbsuit classic on sends.
Some Sylneth and Massive tracks. Big master chains with multiple Ozone 8, Slate tape machine, Waves shuffler and Limiter.
Those should cover all the real life VST usage.
64bit engine on 9.5 version outperforms both 32bit engine and CS 9.0.3 by three more Kramer plugins?!
I thought 64bit processing precision would take a hit on CPU and Asio Performance, but with three more Kramer plugins there is no doubt
it was more efficient.
Did anyone noticed the same, what would be technical explanation? 
Asio Guard: High
48kHz/24bit. 10ms buffer size
Audio Priority Boost, Steinberg power scheme
I5 4460, Asusu Mbo, 16GB RAM, Focusrite Scarlett,
