我的 2070 好像没问题.



Hey @Sniper256, @touzi, @hyun,

Did you see this thread - John Tromp fixed the bug that appeared when using 2080 cards.

Let us know if you have any other issues.



Well, that wont help them, we have modifications that needs to be applied on top of John’s code… We are working on this, but some more testing is still necessary.
