    Hi all, I'm experiencing an issue with the HE which I can not fully understand.
    I have my IG connected to my Host, and with wireshark I can see that the SOF messages are at 60Hz.
    When I unplug my Host and connect the HE, the SOF drops to 30Hz or even lower.

    I see that when I launch HE I get the message "High Performance Counter functions are not supported on this system…"
    Is this the reason why the communication drops to half, or the message is just related to the fact that I do not have the Ardence Windows RTK software? Or what else can it be?

    Thanks for any suggestion/explanation.

    Rob

    The message you describe means that your motherboard or your bios does not support high-performance counters.  Most "real-time" software on vanilla Windows uses these counters to spinlock.  The HE also uses this approach for the non-RTX version.  The HE is almost unusable without these counters.

    I've seen this message mostly with laptops/notebooks and with cheaper PCs (even cheaper Dells).  I suspect that if you were to try a different PC the HE would work normally.

    As for RTX, most people don't need it to run the HE.  We get really good determinism these days on XP or Windows 7 with multiple cores.
