I used to use a R9 270X to play that game(FFXIV) and i didn't experince any driver crashes. However, after i upgrade to an Dataland R9 380 4GD5,the driver crashes from time to time. The issue will occur while running FFXIV under DX11,no problem with DX9.
The driver will crash after 3-5min in game. No oc,all under default setup. Tested driver version from 15.7 to 15.12, it just keep happening.
System OS: Windows10 10587(TH2)
Game Version:FFXIV Patch 3.1(Global server)&FFXIV Patch 3.05(China Sever)(both crashes)
Hardware setup: Intel XeonE3 1230V3, MSI B85M-E45,16G DDR3 1600(Apacer),XFX XTR550 PSU
I noticed that 15.11 driver release note said that it fixed R9 390&390X experience driver crash while running FFXIV w DX11.
BTW ,the problem aslo happens with GTA5, driver crashes after 1-2hr playing GTA5.Not so often like FFXIV but still bothering
tested driver version 16.1, crash still happens
