Hi, my desktop PC (i9-9900K; 64GB RAM) has trouble when scores are very thick/dense in Sibelius but is fine playing the exact same passages in Cubase.
In Sibelius, CPU hits around 80-90% with about 15-18 Synchronized Special Editions instruments playing together/tutti, with MIR Pro, EQ, Compressor on each. RAM used is not much, around 12GB. I've set Synchron Player to load more in the RAM and set threads to max 16 for Synchron Player and VE Pro 7.
1024 Buffer which is more than what I'd prefer.
With the exact same passages played in Cubase it has no trouble. Hitting around 40-60%.
Why is it fine in Cubase but struggling in Sibelius?
I use a master computer to work within Sibelius and Cubase (i7-9750H; 64GB RAM) which uses about 7-12% CPU and very little RAM.
Connected with Ethernet.
