DX11 stutter fix test: ah11stutterfix.exe
« on: October 15, 2026, 09:29:21 AM »
Thanks to everyone who ran the test and sent in their files. They pinned it down: every 10 minutes the game performs an operation that, in the DX11 version, stalled the game for up to a second. The same operation does not stall in DX9, which is why DX9 never had the stutter. It was not your video card, your drivers or the network: the netstat spike you have been seeing was the game stalling, not the connection.

All the data we received showed the same thing, so if this is the only issue, this version should fix it. Please help me confirm it.

1. Install
- Download ah11stutterfix.exe here: https://dload.hitechcreations.com/ah11stutterfix.exe
- Copy it into your Aces High III folder, next to ah11stutter.exe. It does not replace anything.

2. Play
- Start the game by double-clicking ah11stutterfix.exe and fly in the Main Arena as you normally do, for at least 30 minutes.
- It still records stutters the same way as ah11stutter.exe. If the fix works, you should NOT see the stutter at 10, 20, 30 minutes, and you should not see the "Hitch captured" message.
- If you do get a stutter or the message, please send the files: that is just as useful.

3. Send us the files
- Exit the game, open your Aces High III folder, then the "temp" folder.
- Zip every file whose name starts with "hitch" (right-click, "Send to" > "Compressed (zipped) folder").
- Email the zip to htcmail@hitechcreations.com with the subject: DX11 stutter fix test
- Then send me a private message here as well.
- Please send the files even if you had no stutter at all. A clean log is what tells me the fix works.

4. In the email, please tell us
- Your game ID.
- Monitor or VR.
- How long you played, and whether you noticed any stutter.

If you have not run the first test, you can skip it and just run this one.

Doing that now.

After I downloaded and ran, I got a messge "some features may not work" when logging into the game.  It didn't prevent logging, but I'm not sure if that message is relevant to anything.  It didn't reappear when I exited game and logged back in.

Will send any results or confirm the stutters have disappeared.

Seemed to work out for me. No stutters after a brief 32 minute or so Lancaster auto climb.  :aok

hitchlog.txt sent.

I ran a 2-hour tower sitting (ran errands) so no alt tab.

0 stutters   :banana:   seems issue resolved.  :aok :banana:


I think I'll use this test.exe until its patched.  :noid :aok

Will run after work, but I'm confident HT has nailed it, this is such good news, it wasn't a game breaker or anything, it was just something once seen, it was hard to ignore, and you knew it was going to happen just when you'd got on someone's 6! :)

Based on my skill, that's why I never noticed it then. Weird.
