I have come to the conclusion it is the refresh rate at fault here.
Locking the fps to 60 or 120 results in crash.
Turning refresh rate results in more crashing. Especially in Rechain of Memories, crashes loading a save, crashes in battles etc.
Here's a snippet of Rechain crashing trying to load a save with refresh rate set to on.
AMD please look into it, this issue is months old and still you refuse to even acknowledge it in the issues page? Come on man.
UPDATE: Im dead certain that when you use vsync or lock the FPS to 60 or 120 it causes the game to crash.
The problem for definite is "Vertical Sync".
Because turning it off and unlocking the FPS the game no longer crashes as much.
