Presently, with systems up to 6 cores with Hyperthreading enabled, we see Logical processor count and Physical core counts displayed correctly in the IFPro CPU window. We see a table for each and the true values of throughput for the HT Mode.
However, development on these features is in progress.
For the time being in IF, with 8 and more cores, all HT LPs are displayed as physical cores in the IFPro CPU Window.
Note:
With certain systems the automatic calculation for Ideal Flight LPs might only show one LP. In these cases we can make two LPs in Config.ini which handles the in sim mode more favourably. Remember to direct add-on activity away from the primary sim cores with the use of their AM or by starting from a batch file.
