So ever since I upgared to PVsyst 7.4.2, the simulation times have gone up from 10-15 seconds to 15 minutes! I have tried running simulations on various projects and its the same. ( PS: this is not a shading scene issue since Ive tried to even run projects Ive done in the past that didnt take more than 5 seconds to run). the screen on which the simulation seems to take forever is this:

We are working on a tracking layout with an E-W single axis orientation (Modules tracking N-S). We wanted to know if this is possible in the current version of the software. Under help, the E-W horizontal tracking orientation just seems to be a place holder, and not E-W axis whereby the trackers would rotate once a day to orient the modules to the average elevation of the sun on the horizon. Any advice on if and how this can be modeled?
