Recently I wanted to switch to 3ds max 2018, I installed the same plugins I did with max 2017 but the viewport performance is very slow. I open the same file but in 3ds max 2017 it's much smoother. The file has only around 130000 polys and it's very laggy. Does anyone know why that happened? My specs: Xeon x5670 Gtx 1050 16gb ddr3 ram Installed both versions on hdd
