Hi...
Sorry to hear you are having problems with Headshot.
As your system is more than powerful enough to run CC3 and Headshot, please try updating your graphics drivers and ensure you have the latest available.
Please see the link below to check.
Please also run Windows Update to ensure your system is fully updated.
In Windows 10 go to Start > Settings > Update & Security > Windows Update and then "Check For Update".
When complete, do fully shut down your computer and then restart and try using Headshot again without any other programs running.
If you still have problems after checking the above, please send your dxdiag.txt file to
Technical Support so they can check for any problems.
a) Type "dxdiag.exe" in the Search box and click "dxdiag.exe run command" from the search list.
b) It will then check your system for a while, after finishing, click "save all information"
c) Save "DxDiag.txt". and send this to us as an attachment.
Thanks.
