yyskin Posted January 13, 2014 Share Posted January 13, 2014 Hello, I installed AutoCAD on a brand new Lenovo W530 with 2 graphic cards: Integrated Intel and Nvida K2000M. When I just work on the built in screen AutoCAD does not seem to work well, the mouse movement lags. The problem is gone immediately when I simply extend my desktop onto an external screen.. That is all I do : FN key + projector icon, choose extend desktop and enter -> AutoCAD works great. Here is some background info / things I have tried: 1) I disabled Nvidia Optimus in BIOS to makre sure all graphics is on the Nvidia (i.e. disable integrated graphics) -> this did not solve the problem, also after applying the extend desktop trick 2) In the Nvidia 3d settings I made sure that AutoCAD works with the Nvidia card. 3) Nvidia drivers are upto date 4) When I open AutoCAD it appears in the nvida window (in the taskbar) that shows which programs are used by nvidia 5) After extending the desktop I stay with AutoCAD on the builtin screen Please help! It is frustrating to see AutoCAD working so much better on my old Lenovo R500 with ATI HD 3400 than on the W530. Quote Link to comment Share on other sites More sharing options...
resullins Posted January 13, 2014 Share Posted January 13, 2014 Do you have hardware acceleration on or off?? Quote Link to comment Share on other sites More sharing options...
nestly Posted January 13, 2014 Share Posted January 13, 2014 If AutoCAD is not "maximized" on the laptop display, try maximizing it... and viceversa Quote Link to comment Share on other sites More sharing options...
yyskin Posted January 13, 2014 Author Share Posted January 13, 2014 Do you have hardware acceleration on or off?? I cannot access display settings > advanced settings > troubleshooting tab > change settings. It is greyed out for some reason. Unless you mean some setting in the nvidia control panel.. Anyway with just the built in display I have the IGP settings, when I extend the desktop it shows the K2000M. Quote Link to comment Share on other sites More sharing options...

Only extending the display does the trick. Quote Link to comment Share on other sites More sharing options...
resullins Posted January 13, 2014 Share Posted January 13, 2014 This is a setting that has a button in the bottom right hand corner of AC. It looks like a microchip and a lightbulb. Is it on or off? Quote Link to comment Share on other sites More sharing options...
yyskin Posted January 13, 2014 Author Share Posted January 13, 2014 Guys, thank you! I enabled hw acceleration and it works fine. I wonder why extending the desktop would work too..? Quote Link to comment Share on other sites More sharing options...
