WowAce

I too also have some sort of memory leak and wow freezing on me when loading into some instances. Tracked it down to this addon.

Same here... takes so long to track down something like this when it happens when you have a lot of addons. :\ Would constantly freeze me on loading screens. Do not recommend you use this until it is updated.

I also had WoW max out my RAM during loading through dungeons and from Orgrimmar to Thunderbluff through Darkmoone Teleporter, and turning off quest POI also worked to fix the problem. This is on version 0.12.7. Thanks Charix for finding that.

I was having load screen freezes for some days and getting crazy! And one by one I found the addon who freeze my system: This one :(

Just like Charix tell you, the POI system freeze the load screen when you are getting into a dungeon.

Can I give you more info to help you? Just ask...I love this addon. Is one of the very fisrt I installed when I started playing ^    ^

This is just a suggestion and idk if it's even possible...( I know this is the ONLY app of it's kind on WOW) ...can you add an altimeter to this app or is there one I haven't yet notived? Thank you.

I'm thinking that (at least when taking off from land) it could still be done by dead reckoning, with a map of takeoff-point heights at each x,y point extracted from the game's data files.

Seahen - What you are describing is very similar to aircraft "INS" - inertial navigation system. INS calculates your position from your acceleration/deceleration, speed, direction, etc. It's still used by some military aircraft. (The GPS can be switched off during conflicts to prevent it's use by the "enemy" so INS is there as a backup in the case that GPS is not available.) The math used for calculations get a bit complicated and would take an excessive amount of CPU time, especially while flying. 

Sadly, with the new patch/expansion, FlightHUD is causing game lockups on some zoning for the first time for me ever.  I have some ways that I can try to troubleshoot, so I'll cross my fingers.  I really like the addon.

Odd feature request:
Can we get an Odometer?  I mean, you'd think there'd be one in soe addon somewhere, but nooooooooo.  No ongoing tally of distance travelled based on speed over time. :(  After seven years of WoW, I think I should start tracking my travel distance. :\

Sorry for the return delay.  I'm not used to Addon devs being so responsive.  XD

Completely wiped the addon and all settings to ensure starting from a clean slate as installed by Curse.  Also removed all other addons temporarily to limit to this one exclusively.

Issue is not in an instance, though.  It occurs when taking the portal from Orgrimmar to Hyjal.

Astrolabe returns happily with 150.

Symptoms involve WoW memorry consumption promptly shooting through the roof with a delta > 100MB/s.  I left WoW running and "frozen" while adding information here on the first test, then as shocked to note the browser having issues.  Poked at things and found WoW consuming 6.8GB of RAM. :D

In default settings, Quest POI is on.  Turning off Quest POI resolved the issue.

Further testing reveals that tracking of the Completed "Raging River Ride" (Northern Barrens) causes the issue when tracked in combination with still having the Thansgiving quest from last year in the quest log at all.  I think the specifics in this case are edge enough that addressing the exact issue is not needed, however the information may assist if you are seeing this in other cases as well.

Now things work and I am a happy cow flipflap once again, so I shall wait patiently (if possible to be patient) for the potential for an odometer.

The thing of note is that the memory consumption of the client skyrockets without limitation.  On my system, at about 100 MB/s increase.  Perhaps it's a point at which a debugging build that monitors its own memory use would be called for?  If you know what code runs when zoning, especially if it's "on demand" from something that could be called repeatedly or looping, put a memory check into it.  If the memory use spikes suddenly, halt everything and puke informatively.

(I'm cheating, technically.  ^.^  I'm a QA Engineer by trade.)

Months ago I started having an issue where zoning into certain dungeons or the Deeprun Tram would sometimes cause WoW to go into "not responding" and I'd have to use "end task" to force-close the game, then restart it. There was no pattern to which particular instance would cause it, but once it happened, it would keep happening every time I entered that particular instance. Didn't seem to matter whether it was via the dungeon finder or if I was going into something on my own.  I just chalked it up to my old tired computer (Pentium 4 3.2ghz HT, 2.5GB DDR400, 7600GT AGP, XP Pro SP3) not having the horsepower to load some thing or other.

3 days ago I got a newer computer (AM2 4600+ dual core, 4GB DDR800, 9600GTX, Win 7 Ultimate 64-bit) and loaded up all the same addons I had on my old system. The game looks awesome and my framerates don't stutter anymore, just tons better performance. So I'm questing in Twilight Highlands and decide I'll go into Gram Batol and grab the quests in there real quick...and what do you know, "not responding". WTF? I was in queue so I only got a couple of tries to disable some addons and re-enter GB before my queue came up. No issues getting into Vortex Pinnacle, that went fine, then when I was done I resumed going into GB and having the "not responding" come up, killing addons each time before I logged back into game. Turns out as soon as I disabled FlightHUD, no more "not responding". I turned all my other addons back on and still get right into the dungeon no problem. I really like FlightHUD but this issue is bad enough I will keep it disabled until something can be done.

Want a programming nightmare?

Have the artificial horizon tilt relative to the rate of turn speed. This would come closer to a for-real HUD. And keep the antacid and aspirin companies in business.

I'm actually kinda-sorta serious. But wanting you to keep your sanity you can put this on the priority list just after watching grass grow and watching paint dry.

Great mod! Keep it going! (Now if Blizz would just provide the z-axis info and make the ceiling altitudes of all the zones the same. I know, but I can dream, can't I?)

Hmm,

With the new version, I get nothing on screen. Put the old version back and working again. Let me know if I can help in anyway. TY for the updates and the mod.

My whole HUD thing seems to be a bit off-center. How can I change this? Otherwise I love this addon. Very nice : )
