If there is an example what to fill out , spec wise and version wise, please comment below.  
After installing the beta version of desktop ComfyUI, I’ve started testing the performance.  
First thing I’ve noticed that the UI is recognizing the 120hz display, on idle (not moving) it’s 120fps, as soon as I start dragging the things around, it fluctuates around 20-30 fps.  
Enabling back the HAGS , smoothed out the jitter, fps remained the same.

Other thing is that the generation speed is far below desirable.  
Tested the FLUX model, with regular version can do a picture in 6.25sec/ desktop 11.78sec.

Specs:  
Video:STRIX RTX 4090 OC  
CPU: i9 14900k  
MB: MSI Z 790 MPG Carbon  
RAM: Corsair Vengeance 64gb 2x32 5200Mhz

I’ll dig dipper into the power consumption and performance on other models, so far noticed that the GPU power stages are far quieter in Beta version than in Browser one.
