Time for a new PC

Postby Perfect Record » Thu May 02, 2019 19:19

Running Pyramix native V11 on my current PC, I'm getting pretty poor performance. The machine is a few years old, but was rock solid on my last Pyramix version.

In V11, I'm getting slow scrolling, slow launch, poor VST performance and a crash or two a day.

Looking over the Merging recommended configurations, there are about 10 processors listed, and quite a few now obsolete motherboards. There is little guidance as to what features are critical.

I really don't know what factors matter when selecting a processor. My Pyramix rep suggested looking at a 16 core system, which seems a bit intense. Do I need greater processor speed, more cores?

Anyone have recommendations for successful machine build that gives solid performance in Native, especially when it comes to VST performance?

Pyramix Native is singel threaded as far as I can see. Thus multicore processors will not add any significant performance.
Single core speed is key. Unfortunately, the latest processors have not increased single core speed by much, so you might not see much performance increase with a new processor.
It is very unfortunate that Pyramix Native is not multithreaded.

Quite. There is Native (single thread) and then a huge step up to MassCore, and nothing in between. Native is pretty poor on a modern hexcore system with plenty of computing power. Only three VST plugins here and it skips. We need a middle ground.

I have the SMP key on demo at present and have been experimenting with any benefits for Native. None found.

If what you're saying is true, then this is disheartening. I was getting pretty good performances on the same machine, running V8 masscore.

I'd hate to think we've taken a step backwards. There's no getting around it- VST plugs are critical to our work.

I'd still like to hear of any recent builds using current stock mother boards.

I am using a current recommended config from Merging. ASRock Z370M and Intel 8700 Hexcore i7. Have run Native always, but I have a MassCore standard key so I can record DSD on Native if and when anyone wants it.

Preston,
For VST processing, there are only 2 options for Pyramix.
Native is single thread. Period. for this reason, there is very little reason to go with an I7 or any hyperthreading processor. You will actually, get better processing with Hyper threading turned off on an I7 in native.
For VST processing, Masscore is multithread, always.
With that out out the way, there are things tho think about when applying VST plugins in a Masscore system. The big takeaway, is that each channel strip is assigned to a single thread. If you have a bunch of processing stacked up on a single strip or bus, you will run into DSP issues. if you spread the processing out (Putting additional processing on a sub group or similar) you can spread the processing out across multiple threads of the processor.
All the best,
