Although it has only been updated twice recently – to 1.5.0 and 1.5.1. If the performance changes didn't occur after one of these updates, then the issue lies with HD. From a general perspective, you can set the 32-bit true mode (not stretchable) in the HD settings, or try simpler filters than the current ones. You can also try the values 0, 1, and 2 for the tweak. Overall, Hota puts a heavier load on the processor than SoD due to the animations in combat. However, on the map, I don't think it can significantly affect performance. HD's complex filters reduce performance everywhere.
