Autocad Civil 3D 2011 (64 bit)
AMD Athlon(tm) 64 FX-62 Dual Core Processor
NVIDIA GeForce GTX 260 (Graphics Card)
8 gigs of DDR2 ram
Windows 7 64 bit
The cursor (crosshair / mouse) flickers constantly when I am moving the mouse around inside the autocad work space. If I draw a line the flickering gets even worse and it starts to lag slightly. The computer meets all of the recomended requirements as far as I am aware.
The CPU never goes above 45% usage and the RAM never goes past 21% usage. So the computer does not seem to be overloaded especially just trying to draw a line. All the drivers are up-to-date. Is it possible there is some sort of compatability issue going on here or something I am overlooking?
Solved! Go to Solution.
If you installed Update 1 there have been several inquires in this DG about this.
Turn off Hardware Acceleration, then turn it back on.
Helped me solve my lagging issue. Apparently mine was turned off. Turning it on solved the lagging issue. However I cannot update the driver even though it tells me there's a new driver for the hardware acceleration. I've attached screen shots of what happens when I click Yes for it to update the driver. On the system however, I know I have the latest driver for the video card. Can I disregard this or its a completely different entity? Thanks in advance.
Right click on the C3D icon and select Run as Administrator. Once C3D opens you should be able to update the driver database.
