Bricscad & Intel HD Graphics

 I installed Bricscad on my Microsoft Surface Pro tablet for work on the go (for strictly 2D work).  I'm running ver. 14 trial.  It's so glitchy display wise that I can't really use it.

I'm wondering if there are settings to improve performance or is another version of Bricscad that works better?  I own ver. 13, but am trying the V14 trial.

Any help would be great.

Thanks!
Jeff

     I am having the same issue on my Surface Pro 2, is this possible a problem with Windows 8.1?

    Have looked for a newer video driver, but does not seem to be one.

    I loaded v14 onto my Acer Innotab with Intel HD 4000 graphics and Windows 8 to test it.  I have the same problem.  Graphics anomalies when anything is rubber-banding while moving or drawing an entity.  Do you have the latest driver from Intel?  Acer uses their own modified Intel drivers so I can't test the latest one.  Don't know if the same applies to the Surface Pro.

     I have just finishing trying this running V13.2.8 x64 with the same issues as V14.  Just a little more information if that helps.

    Thanks

    I have 4 Machines running HD4000 in W7. No problems whatsoever in 2D.

    We have two systems here running HD4000 under Windows 7 64 bit.  The only major problem I see with graphics in V14 is with loading dialogs.  Instead of having the dialogs appear instantly as a complete dialog I can watch the individual tiles paint in sequence.  The rate at which the dialogs paint varies.  Sometimes a dialog paints quickly. At other times the same dialog can take almost a full second to paint. 

    I do see occasional rendering issues when editing drawings.  Portions of lines sometimes disapear from the screen.  Forcing the screen to redraw restores the lines.  Based on what I see it looks like Bricscad is erasing a small rectangular area then redrawing just that area rather than redrawing the entire screen, but the rectangle that is erased is slightly larger than the area redrawn, or maybe that the lines that are disappearing are aligned along an edge of the rectangle being deleted and with the interpolation necessary to concert the lines to pixels the line portion is close enough to the edge of the erased box to be erased but not close enough to get redrawn.

    I am having a similar issue. Having transferred my install to my new laptop (Windows 8.1 using an Intel HD 4600, (it also has a NVIDIA GeForce GT 750M which I am having issues making default...but that's not an issue for here)), the display now doesn't show the 'snap' icons and loses items as they are moved (they reappear once placed in their new location), and selection boxes / items appear offset to the mouse location. This makes drafting very difficult!

    Prior to the move the install worked fine on a Windows 7 desktop with a Geforce graphic card, so it appears to be an issue with the Intel graphics.

    BricsCAD Version 14.1.07 x64 (I'm having the same issue with Version 13.2.4)

    Great news, got this to work on my Surface Pro 2 running Intel HD Graphics 4400 under Windows 8.1 x64.  Here's what I did:

    - Right click on the Bricscad icon you use to run the program and select Properties, then Compatibility.
    - Click in the box for Compatibility Mode and change to Windows 7
    - Disable display scaling on high DPI settings
    - Press Apply, then close and all done

    Everything works fine now under Bricscad V13.2.8 x64.

    Check that you're using drivers from Lenovo rather than generic NVidia drivers. I tried the basic NVidia drivers because they were newer (= better?) but there were issues with the display control panel and graphics, so I immediately did a system restore back to the Lenovo-branded drivers.

    Last time I checked, navigating to the driver page from the main Lenovo site was all but impossible. Try doing a 'net search for {"Drivers and software" "xxxx" site:support.lenovo.com} where the xxxx is your model number. There are (for my model, at least) different downloads for Win7(64) and Win8(64)
