Tekken 8 is, I am told, a very good fighting game. Not that I'd know too much about this sort of thing, as my reflexes are now old and haggard enough that I could be beaten by a well-trained dog that licks the buttons on command in anything that requires fast-paced controls.
Sigh. Anyway, what I do know about is Nvidia GeForce driver updates, and the notes for the most recent release confirm that Nvidia is aware of an ongoing crashing issue in the game.
Listed in the release notes for the latest 552.44 Nvidia driver is the admission, under «open issues», that «Tekken 8 may randomly crash during gameplay on GeForce GTX 10-series graphics cards».
A quick Reddit and Steam community search reveals many players complaining of random crashing and hard locks while playing the game, although it must be said that while a fair few are reporting using 10-series cards, the crashing issues don't seem to be based around them exclusively, as many are still reporting problems with a variety of hardware.
South Korean players have already complained about crashes said to be linked to Intel's Core i9 processors, and while that issue doesn't seem to be limited to Tekken 8—and motherboard manufacturers scramble for a potential fix while fingers are pointed by both sides—those of you with a high-end Intel chip or an older GPU may now at least have some explanation for the mysterious crashing issues in the game, although a proper fix in both cases may take some time.
