Slowdown and stuttering during complex machining

[AdrienThor]

Hello !
A few people and I on the PrintNC Discord platform have noticed significant slowdowns when sending information during demanding operations (adaptive, truncated, etc.) when we're in the program window. Significant slowdowns, and for me, even freezes of a good second if I'm unfortunate enough to click on something. I'm not talking about slowdowns in the software itself, but rather in the machining.
It doesn't happen in other windows, especially in "console" mode.
I admit I haven't looked at how much power I'm consuming in the console window, but in the program, I'm at 100% of my CPU (with an integrated graphics card).

IO Sender Version: 2.0.45
Controller: Grblhal
Windows 10
Lenovo V14 Gen4 Laptop
Connection to the card: USB

If you need more informations, just ask !
Thanks :)
