yeah I’m currently seeing a lot more reports on google about new eevee being much slower in viewport and rendering. when I switch to cycles the viewport works fine but when I switch to eevee next EVERYTHING is slow even trying to move my mouse. same thing happens if my rendered mode is set to cycles and I switch to material preview is goes slow but switching back to rendered preview while on cycles its not causing that issues. my solid mode works just fine, so it definitely has to be some issues going on with the new eevee. I’m guessing going back to 4.1 version would be the best issue right now so I don’t run into slow times on my viewport.
