3D graphics display with different hardware

Interested in getting some input on how well 3D graphics in BricsCAD 12 for Linux works with different hardware.

I am running Arch Linux and have a brand new work station with amd fx-8150 processor and AMD radeon hd 6700 graphics. I am using the proprietary catalyst graphics driver. GPU rendering does not work (error message is displayed). 3D display performance feels very unreliable. During selection sometimes part of the geometry becomes invisible, and when using for example the push/pull tool the geometry is flickering during the operation instead of transforming smothly. Outlines of objects also displays rather unpredictable during selection and selection preview. I have tried the different GL swap modes, but none seems to work really well. I also experienced this kind of behaviour with v.11.

    Thanks for posting. I was contemplating buying a thinkpad X121 with AMD Fusion, since I hoped the graphics (radeon HD 6320) would be more likely to work than the intel GMA 3000 of the model with i3 processor... but for the time being, the only supported hardware seems to be nvidia.
    Both the workstation and the laptop I use have intel graphics, so I did not yet see anything of the new GPU-powered graphics modes.
    I filed a quite comprehensive support request concerning the flaws of the current CPU rendering some time ago, and a fix had been scheduled, but no progress is visible so far.
    I would also be interested in hearing from other users with supported hardware if the performance is acceptable and the glitches (disappearing selection etc.) are actually gone.
    In the light of experience with v11, upgrading to v12 at this point would only be an option for me if there was an unambiguous commitment from Bricsys that these issues will be resolved during v12 lifetime.

    My use of v12 is still limited to 2d because Radeon remains unsupported. I hope we get a fix soon.

    Currently running Bricscad on a Asus Laptop
    Nvidia 560M
    Seems to be working, but I haven't had time to work on what i consider large assys.

    My desktop runs 2 crossfired 3870s.
    I love ATI hardware, but with linux it's hit and miss.

    Hi

     

    I  tell ya, one thing really cool about Bricscad's 3D engine, is seems to support SLI.  I recently put together a new machine "check out the pic" using two NVidia GTX560s paired up in SLI mode.  Now I haven't fully tested under Linux as I'm having a bit of a fit turning on SLI with dual monitors, but the performance is really good with just one card.

     

    With Windows 7, and SLI mode turned on, the difference truly amazing!!! The motor (see pic) on this unit is quite heavy to work on while in high quality mode, a bit sluggish dragging around on one card, but with SLI powered up, whoa,  it's almost as fast as 2D!

     

    I tried with Acad 2012, after going through the "your cards are not on the happy list so go away" and manually turning on hardware acceleration, well, it's not half as fast as Bricscad.  

     

    I'm sure once you radeon guys get up and running, you be happy in Bricscad 3D land.

    Cheers

    i've never used dual Nvidia cards.

    what are the fps' compared to running a single card?
