No, it's still the same as before. You need to choose the driver + GFE in the installer if you want GFE. There's no GFE option if you install your drivers via GFE updater. So it's only while your OS fully boots and then it goes away or what? Nothing unusual here on 1809, CPU usage spikes to ~10% for a second or two while the service loads after OS (re)boot but that's normal. I'm booting from the HDD if that matters. It goes back to zero afterwards. Could be some fast-ring bug if your CPU usage doesn't drop.
