HT is bug hunting for stutters, anything can happen and is.
Suffered my first ever CTD today in AH2.
Was fighting Mandoble in his 109 and me in F4U-1 we both CTD at exactly same time.
Apparently Mandoble was at a count of something like 5 ctd's today.
5 Mins later i had a hard lockup, having to power off XP to get out of AH.
Stutters, well apart from a few when i took off from A8 whilst on climbout. Once fighting i never noticed a single stutter, so that aspect appears to have been helped from my limited play time today.
