Happening to me too. Started a few weeks ago. Used to work fine. Either BSOD reboots machine, FFXIV client crash, or sometimes video goes black for like 15 seconds then game comes back. Can happen anytime and does seem to be getting worse. Does seem to be video related. Wonder if they changed something in one of the recent patches. Settings at High Laptop with Nvidia 580m SLI on Win7. Cards were consistently running around 80c during Fates and such. So I cleaned the fans, downgraded the drivers, lowered in game settings, and disabled overclock on the CPU. Runs about 10 degrees cooler now with about 60 fps but no improvement on crashes. Have run all diagnostics. No errors. Only have problems in this game. Will see if flattening the unit will help this weekend. Will let you know.
