Question Circuit sim has brought my new build to its knees!

Hey guys;
I've got a new build (April 2020) with the following specs:

ASUS Tuf Gaming X570 Plus WiFi
Ryzen 7 3700X with Wraith Prism cooler
Gigabyte GeForce RTX 2070 Super Windforce OC 3X 8G
Monitor 1: NEC EA244WMi @ 1920 x 1200 @ 60Hz, Monitor 2: Samsung 2494HS @ 1920 x 1080 @ 60Hz
G.Skill Trident Z Neo 32GB (2x 16GB) DDR4 3200MHz
2ea WD Blue SN550 NVMe M.2 1TB SSD
Seasonic Focus GM-750
Fractal Designs Meshify C (no glass)
4 case fans (2x 140mm front, 1x 120mm rear, 1x 120mm top) controlled by ASUS Q-Fan control.

Windows 10 Pro x64 ver 1909

I noticed the other day that when I run Tina Basic circuit sim, my CPU % goes to near 100%, with the one process (Tina) using all of it.
Specifically, when the virtual oscilloscope is running. I haven't tried any of the other virtual instruments. Tina does not appear to use nearly as much resource when I run a 'normal' analysis using 'transient' or 'AC' compared to real-time view on the scope. Note also that I am only running two channels on the scope.

If I try to do anything else while the sim is running, it takes forever.
Thankfully, I can control how many threads Tina uses. It was set to Max by default, but when I lowered it to 8, Tina used about 55-60% CPU and other app could run.

I ran a brief test with Tina and a train simulator (Run8 V2) which doesn't use much resource.
When Tina was running with threads set to max, Run8 frame rate would drop from about 37 to 15.
When I set Tina to use only 8 threads, I got about 35 FPS in Run8.

I am running with the AMD Ryzen High Performance power plan.

Are there any other settings (in Windows) that I should be looking at?

Thanks for your help

You should ideally be on Windows 10 version 2004, soon we'll be upon a newer version this year or late this year. Outside of that, your system is working as is, have you tried an overclock on the processor though I'm sure you need more cores and threads more than core clock speeds.

Thanks. I have non-essential (ie security) updates turned off, so I guess I'm not quite up to date. I will do the update today, then turn on automatic updates.
I am running an OC profile on the CPU and RAM. When I checked, the CPU was running at 4GHz, which is slightly OC'd.

I am trying to update Windows from ver 1909 to 2004, but have failed 2x so far with error:
0x8000ffff, and 2nd time, 0x80004005.
I ran the Windows Update Troubleshooter, and it said it made changes. I rebooted but have not tried the update again.
I created a partition backup before doing anything.
