Hi, I did try reducing the cloud draw and texture quality. Skymaxx menu was showing more available gpu memory, but this this did not have any impact on the gpu frame time. I am running on 3x QHD resolution, however, I am comparing the performance relative to Skymaxx v4. From 30fps to 10fps is quite a performance hit.
I guess especially when using real-world weather there is a need for an adaptive quality mechanism which perhaps reduces the number of rays to speed up the gpu frame time. After all this is a dynamic simulation, we don't know when we are inside the cloud and when few clouds only!
