I recently upgraded my OS disk and kept my game library HDD.
After installing everything and Steam recognizing that I had already had Destiny 2 installed, I updated and launched the game, and as soon as it started my graphics crashed, and I had to reboot. I reverted my overclocks on GPU and CPU and performed a clean reinstall, and still had the same problem. If I let the game run in the background and put another window on top (I run the game in windowed fullscreen mode), I can see the game behind running just fine, but as soon as I select the Destiny 2 window the graphics crash again.
I can’t seem to find a possible source for this problem.
