In XTweak section of XXHE I got 'Time Performance Index': N/A.

From Web search I found 'Command Prompt' instruction to enable HPET:- bcdedit /set useplatformclock true

after reboot and XXHE XTweak refresh I now get:-
'Time Performance Index': Optimal

This worked in W7 even though I do not have HPET option in BIOS.

See http://www.neowin.net/forum/topic/1075781-tweak-enable-hpet-in-bios-and-os-for-better-performance-and-fps/

Yes that was it, I've put Q5 to 0 and OK now

Thanks

Started XXHE this morning and it was slow to respond. Checked with Task Mgr and found that XXengine3 was continuously using more than 50% cpu during play. Stopped play and cpu load dropped to very low %, no other processes were using high cpu %.
Same problem after a reboot.

I've done this check before with my current configuration and XXengine3 was only using about 2% cpu during play.
