Hi everyone,

I am curious if anyone has this issue, I am running on RTX3060 Ti, the benchmark case showed that it can achieve 2654 MLUPs.

Then I tested the cylinder in a channel case with INTERACTIVE_GRAPHICS on, now it drops to 9 MLUPs

The bandwidth is dropped from 408 GB/s to 2 GB/s too. Is that normal or something is wrong? The memory seems to be only 684 MB on the device, far less than the maximum 8 GB on the GPU. Anyone knows what could be the reason? Thank you!
