You clearly don’t understand how GPU works , nor you are tech-savvy . So stop pretending for a moment and listen ( or rather , read ) .
It is impossible for a game to specifically target a GPU model to destroy . Read this again 10 times and memorize that . This is especially true because 3080 TI , 3090 and 3090 ti actually run on the same chip .
Yet you are seeing more faulty reports with 3080 ti , why ? Because there are more ppl who own a 3080ti when they pick up second hand and refurb GPU when the mining trend dies down . 3080ti had a very steep price drop .
According to steam hardware , there are roughly 6 - 8 times more people who own a 3080ti than a 3090 , so naturally you are going to see more 3080ti faulty reports than 3090 and 3090ti . However that doesn’t mean there were none . Browsing thru the threads and topics I have seen people mentioning their 3090 and 3090 ti getting burnt down as well , but in less quantity than the 3080ti which also make sense because there are more gamers with 3080ti .
The game seems to push GPU to the edge of their workload and when hardware is operating at their maximum efficiency , any loose screws tend to fall off easily . And this is a perfect example of that .
Specifically , Diablo 4 is not very well optimized , but it did not technically brick your GPU . There could be another unoptimized game , which also utilize 100% workload of your GPU and will burn down your GPU as well . The MMORPG by Amazon games , New world has also did the same thing when a bunch of 3090s ( 3080ti weren’t out at the time ) broke down running the game .
What you need to do is refer back to your GPU manufacturer , clearly something is not quite right with the Gigabyte 3080ti , I don’t see many users who have Asus Rog Strix having the same issue . If Gigabyte does not fix that , you could be buying another Gigabyte 3080ti and it will brick down on the next game which has unoptimized performance and the cycles will continue .
Also enough of the " I can run RDR 2 fine but why not this one " . We talked about this many many times . Different games run on different engine . Do not expect the same performance from every game engine . For those who are not tech-savvy , which is about 95% of you on the forum , memorize that hard before you try to embarass yourself infront of the game tech again and again. It isn’t helping , it doesn’t solve the problem and it is only going to proscratinate their work .
