Constant lag, stuttering, and freezes every few seconds with Steam version of Substance 3D Painter 2026

The Steam perpetual version of Substance 3D Painter 2026 has significant lag and stuttering every few seconds. I saw patch notes claiming this has been fixed, but it has not been fixed on the Steam version it seems.

Specs:
OS: Windows 11
GPU: NVidia RTX 5090
CPU: Intel Core Ultra 9 285K
RAM: 64GB DDR5
Storage: 2TB+ NvME

Things I’ve Tried:
Reinstalled
Close Logitech lamp array services
Restart PC
Force Substance to use dedicated GPU

Any way that Adobe could look into this issue would be great. It’s negatively impacting my ability to work.
