Okay, sorry for the stupid basic questions which you've probably already done anyway - but are you running any background programs (Origin/Steam overlays, MSI afterburner, Riva Tuner, things like that?) It seems that background stuff can interfere with the running of the game.
Both you and Sugram - are you sure you applied the workaround correctly? Like, leaving a space after the last quotation mark after .exe". Again, I apologise if this comes off as patronising, I'm just trying to help 
So C:\Games\Dragon Age Inquisition\DragonAgeInquisition.exe" -ShaderSystem.ShaderQualityLevel Ultra
Also, they made a mistake Hollerboller mate. It happens, we're all people, no matter our jobs, and none of us are flawless, and no-one should be fired here. It sucks that the patch has broken things for people, but they're doing their best to fix it.
@Ex-Paladin - have you tried the workaround? That fixed the scar issue for me.
No background programs other than origin, and yes the workaround was applied correctly. As i said no problems at all before the patch with the same system settings. GTX 780 3GB, 16GB Ram, game on an ssd.
And i agree, none of us is flawless, but again, the performance they showed us with this patch, release it like that, is a no go and there is simply no excuse for this and i had lost my job.
That dont mean i wish them to get fired, dont get me wrong.
For me it looks like they have simply no qa for pc and if they have, how could that patch pass qa? I mean you have to simply fire up the game on ultra settings and load a save and you see, ups there is something wrong, we can't release the patch.
So yeah, there is no thanks from me for bioware because they made a terrible job in the first place with this patch.
Sorry for my bad english
