I have just installed my 3070 and giving it a go, I've compiled the CUDA version a few times but only for older cards.
I hear that I have to roll back my driver to get it working for 3070, 3080 or 3090 cards, but not sure which one. I can't get it to start at all right now on the RTX 3070, using the driver that comes with CUDA development kit 11.2.
Aside, I think I know where to fix this, if I can just get it to work on my card so I can give it a whirl :/
You wouldn't need to rollback your drivers tho? It should run using the latest CUDA & drivers (and ofc crash due to the error), atleast on windows.
It runs on legacy compatibility mode using _75 (with CUDA injector at ~500M/k/s). Yet nowhere it is documented how to compile against compatibility mode and what the effect of it even is.
Docs say I should compile against c80,sm80, so will test what that does using legacy mode. Whatever that mode even does.
