It does not use cutting edge tech at all and unchanged for more than ten years. Was told no OpenGL used. Unless information is incorrect, the slowness is baffling. Slow - charts are drawn literally line by line instead of just appearing. Super laggy pointer control.
And yes I use both Desktop and Fusion for years.
