Settings for TurboCAD Platinum - Geforce GTX 3090?

Hi, I’m a Joiner who makes YT videos of my work & uses TurboCAD Platinum to draw the jobs before building them, i’m hoping someone here has some suggestions -,
i just bought a new PC to help with the video editing & drawing
Windows 10 Pro
AMD Ryzen Threadripper PRO 3975WX 32-Cores 3.50 GHz
GEFORCE GTX 3090
256GB RAM.
When turning/panning a 3d rendered object the screen doesn’t pan smoothly, it pauses then jumps to the place i’ve panned to, the CPU & GPU are doing hardly anything, it’s not much better than my old quad core CPU & 6gb Geforce GPU.?
Does anyone know of a setting that can make CAD more efficient at using what hardware is available to it?
Pls keep replies at an idiot level 🙃
Thanks.
