WARNING:
If you were using some Grin miner, you will get system freeze using WildRig. That miner changes driver behavior, because of recommendation to use command setx GPU_MAX_WORKGROUP_SIZE 1024. So if you get freezes, now you need to specify worksize precisely. Like --opencl-launch 20x256 instead of --opencl-launch 20x0.
Well there you go then, it's exactly what I experienced the other day when I wrote it to you in the Discord. Glad you found out what actually happened.
I originally thought it had something to do with the .net runtime.
What is the "regular" max workgroup size in Windows then, assuming the variable would never be forced/set by the Grin miner?
