No its not a overheating related, because it also crash with just 70 - 75°C and was never a problem before 1.2

Since some other people attribute this to GPU overheating I logged my temps in HWinfo during a crash.
GPU hotspot max temp reached 81C. I´ve also attempted to throttle GPU usage in AMD software and ingame with lowest settings + 30 FPS max. Still crashes within 5 minutes.
