I would like to know if you are experiencing the same thing as us.
On our workstations, Preform 64 freezes after 5 to 10 min. This sometimes freezes Windows as well.
We have lost some CAD works on one station due to this problem. Siemens NX 12 was unable to save a job in progress and PC had to be rebooted…
Anyway., the config of our workstations:
HP Zbook Studio G4
Core i7 7th gen
16 Gb Ram
The problem does not seem to come from the graphic interface but rather memory management.
