I just installed AutoCAD 2015, and have found that I encounter display errors when I try to run the hardware acceleration with my NVIDIA GeForce GT 735M. The error I am getting is that the AutoCAD screen will not display correctly. It either flashes, goes black, or leaves a trail of crosshair artifacts behind the active crosshairs as I move them around with the mouse. Or a combination of all three of these things occurs. If I turn off the hardware acceleration, everything works fine. Also, when I switch to the onboard Intel HD Graphics 4000 I can turn on the hardware acceleration and everything appears to run fine. The tuner log for both the Intel and NVIDIA GPUs states that "The card and driver meets the recommended requirement." But it appears to me that there is some inconpatability issue with my NVIDIA GPU.
When I run AutoCAD 2014, I can use my Intel or NVIDIA GPU with hardware acceleration and everything works perfectly.
Anyone have any insight into this? Is this a bug with 2015?
Hello from France
Welcome to the Autodesk/AutoCAD Forums !
YES the 2015 is using some new/special features at the graphic card driver ...
2014/2013 is running OK, I imagine !?
Most often if you disable the Hardware Acceleration, you must have no problem !?
LINESMOOTHING = 0 could help but I don't think so !?
... Then you will have to wait for an update of your NVidia driver ...

Hi,
>> It either flashes, goes black, or leaves a trail of crosshair artifacts behind the active crosshairs
I had exectly the same problem with my Quadro K1000M, and an update to the newest drivers helped.
But there is another thread >>>here with GTX760<<< (@darawork) who don't get AutoCAD running on the nVidia card at all, AutoCAD recognizes only the Intel gc.
So I would be careful with updating the driver for your card (you may try it, but maybe you'll then need to reinstall the old one? I don't know).

Hello
If you have a NVidia Card please try the Disable the "NVidia FXXA Feature (Anti-Aliasing) !
Sometimes it could help the 2015 to run fine EVEN with the Graphic Hardware Acceleration = ON !!

I don't think so, but ...

Thank goodness you guys are lifesavers...I have the NVIDIA GeForce GT 640M giving me same issues with crosshairs leaving ghost trail.
turned off hardware acceleration cures the issue.

Hi mates.
I found a solution for my pc.
My graphics is an AMD RADEON 8850M, but i solve changing the settings on the autocad 2015 options.
Click with right button, than click in options.
Go to System tab, there is a window called Hardware acceleration, open graphics performance and than disable.
in my case works.
