http://www.zwsoft.com/forum/viewthread.php?tid=2536 Hello I recently got a new Graphics Card for my machine (NVIDIA Quaddro 2000). Accordingly I anticipated some accelerated performance in the ZW interface. Sadly, I cannot see it.. (at this stage). Do I need to re-instal ZW to have it "find" my new graphics card.

Frankly speaking, ZWCAD does not use too much of the graphic card ability, so there is no obvious accelerated performance by using more advanced graphic cards. But genereally, a better g-card can run ZWCAD more smoothly. huangy8949 2012-12-13 11:07:33
