Hi, It seems that the video card of @Wolf-S is powerful enough, and the driver is recent.
I'd try the following: Try disabling the following:
Preferences -> Performance -> Multithreaded Compositing
and then restart.
If it is not enough, try to check "Deactivate Native Canvas" in the menu Edit/Preferences/Technology preview (Pc) or Photoshop/Preferences/Technology preview (Mac), then restart Photoshop.
@c.t.Hamm can you give your system info?
