I have started to work on Bloko Raceway on this computer and i had this problem when trying to import Ref shapes into Constructor (In this case, M.Dts, the BL Minifig shape)
After importing, constructor LAGS when i just look at it, which is just impossible since it worked fine on an Nvidia Geforce 5200 FX, But now i switched PC's and got a 8400 GT, it's like that.
Any solutions?
