Hi,
----------------------------------------just updated one of my rigs from Win10 to Win11. I noticed that the client now uses only one GPU, instead of two. I have 1050ti and 1070ti installed on this system. When I start the client, it says that device0 is working on one WU and device1 is working on second WU. However, the task manager shows activity only on 1070ti (and temperatures of the 1050ti stays very low). Has anyone else come across this? I'm not 100% sure if this is a win11 feature, or if it started already with win10. But I'm sure that at some point with this config, both cards was occupied. |

Also, it seems that OPENCL GPUs are now listed twice
