***PLEASE NOTE THIS DOES NOT RESOLVE THE ISSUE IT ONLY PROLONGS THE CRASHES. AMD WILL NEED TO FIX IT WITH A DRIVER UPDATE IN THE FUTURE STILL.***
As I and many others are probably sick of waiting for a fix for these crashes, I have discovered a way to make them a little more stable but not entirely crash free.
Rule 1) NEVER set vsync options on, these crash the game way more often.
Right well you need to follow the below.
1) Set Resolution to 720p and any of the three options Fullscreen, Borderless Windowed, Windowed.
2) Set Framerate to UNLOCKED. Any other than 30 or unlocked you WILL crash.
3) DELETE and uninstall AMD Adrenaline (This is the cause of so many of the crashes, remove it via AMD Software or AMD settings in Add or Remove Programmes)
Using the above I've managed to get to Leon in Rechain of Memories somehow, it still crashes but it's not immediate now.
Report back on your findings.
The more we know, the more AMD will know, the more chances AMD will fix down the road.
Note: I am using the Rog Ally.
UPDATE 1: Tested going into 5 heartless battles in a row, not crashed yet, but it does happen at times and sometimes when pausing in Rechain.
Pause crash is pretty much gone in KH1 now too I think?
CRASH FINDINGS
KH1 - Pausing when on fps 60-120
KH2 - Crashes during Kairi and Selphie scene when cutscenes are locked to 30 fps, Consistent crash in Twilight Town Train Station when transitioning areas if fps is 60-120 or refresh rate is on.
Khrecom - Good luck, this one is unstable, crashes on battles, crashes when leaving battles randomly, crashes when loading, crashes when saving, it's all pot luck with Recom, some things work, some things don't.
The most important setting I think is 720p and Unlocked with no Refresh Rate.
Its a work around but a very hit and miss one...
