Hello, so literally just today my game started just not launching at unless I had the 4 GB hack removed from my game. But I continuously crash in Denerim still. I do have IA installed but even without it before Denerim was unplayable until I had the hack installed. I have no clue why this is happening and it's actually really upsetting cause I wanted to do a few playthroughs with Origins. Even when I have the graphics low in the hopes of having it work out, Denerim is horrific because of glitching textures and the Wonders of Thedas is basically a black hole with a few things I can click on.
Dragon Age Origins can get very crashy on modern hardware. I have my fingers crossed for a remaster that fixes these issues.
One way to possibly limit the number of crashes is to set the CPU affinity to 1 core. This comes with the downside of reduced performance.
I don't work for EA.
