Any support for RTX 4ooo cards?
what rtx4000 cards are you talking about?
Nvidia quadro, used for video editing and some medical applications

In a RTX4000 you will find a TU104 processor and GDR6 memory, the same processor you will find on a RTX2080 also using GDR6 memory. So I thought T-REX should work here as well or doesn't it?
Are you using actual drivers "R460 U3 (461.40)" ?
Are you using t-rex-0.19.10(cuda10.0) or t-rex-0.19.10(cuda11.1) ?
Prefer to use t-rex-0.19.10(cuda11.1) on Turing processors, it will support the newest one.
Let us know how it's going, I'm rather curious about this.
