Thanks - you're right - I have the i7-7700HQ and the Passmark score is about a third of that Ryzen beast.  Poking around in other threads, I think my Pianoteq Performance Index is probably about right so I'll relax.

My stage version runs on a Windows netbook as well as my 2008 Acer laptop which is basic.  Pretty near it's limit, but the sound doesn't seem to lack.
By all means up the spec requirements if some could benefit from it.  I suspect improvements from updates always carry a small extra burden for the computer anyway.  But even if some of us wouldn't beneit from the vastly improved specs because of our lowly machines, it doesn't really matter, does it?

What we have is excellent already!

If that is the case though wouldn't it be better if Modartt ran Pianoteq as an analogue instrument rather than software? That way they are not limited to the consumers PCs or Laptops. That way they can just update the software inside the analogue stage piano or home style piano.

If you put Pianoteq into a stage piano, you'll be stuck with whatever hardware they chose to use. In contrast, the computing performance of consumer PCs and laptops is always increasing.

... Isn't there huge headroom to add complexity to the piano models in Pianoteq? Or is there very little that can be added to the models.

My understanding is that the models we can buy are restricted in certain ways so they run in real time on most computers. But the original models are so sophisticated that even the most powerful off-the-shelf computers will come to a grinding halt.

WTF? I have a quad core 2.8GHz i7 (laptop version), but at 256 voices, I get a CPU overload warning, Even at 128, I see red spikes. Do I have a problem with my system? Greg

Also there are significant performance gains between CPUs generations. That could be another reason he's getting huge performance, while your system starts to run out of gas. The clock speed and CPU model can be irrelevant for assessing CPU performance between generations. For example, it's possible that a 9th generation i3 at 1.5Ghz easily outperforms an older 5th generation i7 at 4.0Ghz.

Here is a question: My PC has a Ryzen 3700x CPU. 8 Cores and 16 threads. I can set polyphony at 256, hold the sustain pedal down and go crazy on the virtual keyboard with a mouse. This doesn't even max out a single core. In fact with low polyphony people are running Pianoteq on a Raspberry Pi which has a rather pathetic CPU. The pianoteq performance index is 167-196 or 194 ((it varies)) when I play the demo song(not sure what that actually means), no overclocking and on a balanced power plan.

4 core CPU's are everywhere and according to the Steam hardware survey 6 cores are becoming commonplace. Isn't there huge headroom to add complexity to the piano models in Pianoteq? Or is there very little that can be added to the models.

Just curious
