It should make very little difference as the operating system will avoid scheduling threads onto the additional logical cores as long as real cores are still available. If the Jolt physics change of 6.00 goes live there might be some benefit to having HT enabled as that apparently can take advantage of hyperthreading/SMT.
Generally hyperthreading should be left enabled for maximum performance. The reason some games suffer reduced performance with hyperthreading is because they are not aware of the difference between physical and virtual cores and have very low, if not even negative, scaling with thread count. Once both logical cores of a physical core are scheduled, each logical core runs at roughly half the speed of the physical core. If one of those logical cores was running code on the game's critical path that is not speeded up significantly by multithreading then the game will run slower.
