Since I have been playing on the ISLE OF SIPTAH map I have noticed a great warming up of my GPU I cannot say if it is a bug or something like that, but in other games it does not happen to me. Can you explain the reason for this?
About what temperature are we talking here? Most cards nowadays can run fine at around 90°C, only above that it will be too hot and can start to damage the card.
So if your card is on full load and heating up to something below that number I wouldn’t worry that much.
