CUDA Hashrate not being reported about xmrig-cuda

[Spudz76]

This occurs on all old slow cards, increase bfactor and/or bsleep or reduce intensity (blocks*threads) until it has time to show you stats. Of course that reduces the hashrate basically only so you can see the hashrate... the 60s or 15m should eventually populate as they have for you. Your card is getting 10 hashes and probably burning as much or more power than the CPU is for its 1000 hashes.

RandomX also requires 3GB or more VRAM otherwise every dataset access has to come across the PCIe bus, and if you're on a X1 slot extension the xfer rate is even worse than X16.

I run an xmrig with no GPU support included on the CPU (for RandomX) and then run another xmrig with CPU disabled and the GPUs on whatever MoneroOcean supports that still works on GPU, like CN-Heavy types or GN-GPU. This is because the backends have to run the same algo and RandomX is basically useless on GPUs (by design).
