I am currently using solidworks 2010 with service pac 2.1. I have a xi computer w/ a pentium 4 3.2ghz processor w/3.2 g of ram. I am using a Quadro Fx 1800. Anytime I run solidworks I experience a lot of lag and freezing. I recently upgraded my video card to the 1800 and it has been doing a little better as far as crashing but still lags a lot. When I run solidworks rx diagnostics everything checks out excpet the program being able to locate the service pack database. Would this be one of the reasons Im experiencing lag or is it because my system needs to be updated. If so whats a good fix and how do I locate the service pack database Thanks for your help.
