Hardware Acceleration Stopped Working

Apr 17, 2012 11:32 AM

So last night when my computer shut down, it made some updates. I believe it made both windows (Windows 7 64 bit) and nvidia updates (Nvidia GeForce GTX 580). Prior to today, 3D worked great on this machine. Now, all my 3D projects are running slow, spiking the CPU, and showing Context3D.driverInfo is showing “software (direct)". I have uninstalled, reinstalled, and rolled back my Nvidia Drivers but nothing has worked. System Recovery is not completing so I can’t roll everything back… any advice/solution? I am running all Adobe Air 3.2 projects from Flash Builder4.6 with the Air3.2 SDK.

    Could you post your dxdiag report so we can take a look?

    Just for sanity, can you double check that HW Acceleration is turned on in Flash?  To check this load any Flash content, Right Click > Settings > Far Right Tab > Make sure that 'Enable hardware acceleration' is checked.

     

    Thanks,

    After updating your video driver, do you still see the green line in videos with hardware acceleration enabled?

    Ok, it should be fixed with the new drivers but please let me know if you encounter it again.

     

    Thanks!
