Hi everyone, First of all, thank you all for helping me:)
Sylk: On the power management side, I removed the standby from my SSD from the beginning, so it can't be that. Indeed if you run with a GTX 1080 I don't see where the problem is with my card.
yannick.petit: I had this checkbox, we'll see if it doesn't improve my problem. Thank you very much.
In the end, if solidworks recommends the Quadros, it's because the Geforce are not?
Well, I can't install the Studio driver, it tells me it's impossible. Since I unchecked the box that yannick petit advised me to uncheck earlier, SW behaves better in MEP. There are still some slownesses but it's much better.
Good news if there is improvement. However, there is no reason why you can't install the Studio drivers. Maybe it's not the version compatible with your machine.
