Im trying to track this down, and have been running some utilities, like filemon, to see whats happening. In doing so, I noticed a wierd issue.

In the past, we had a wdb file, that contained a cache of items/mobs/etc. In 2.0 they moved it. It is supposed to be in the new Cache folder, but mine wasnt. I manually added a WDB, then an enUS folder into the cache folder (Cache\WDB\enUS) and my framerate went up, my network traffic went down, and I got a bunch of cache files put into that folder by the wow client.

Can anyone else try this and report back on lag/issues it resolves, or doesnt resolve.?

... That would explain so much.



I'll check when I get home. Any particular hoops once you create the folder? (I'm assuming mine's missing, given how unpleasant things were last night.)


Edit: Yup, it was gone, and yup, this worked great.

I've been running 500-2000ms ever since the patch was released, but I've talked to other people and most of them seem to be fine. My internet outside of WoW is running just fine, so I'll give this a go once I get home and hopefully it'll resolve this issue. I'm seeing the same things though, naked people/slowly loading gear.

Three datapoints for you :

1. My Windows box at home has the Cache directory, but only a Survey.mpq file in it - no directory hierarchy at all.

2. A TBC Beta install on the same machine has Cache/WDB/enUS, populated with several cache-looking files in it : creaturecache.wdb, itemcache.wdb, itemtextcache.wdb, pagetextcache.wdb, wowcache.wdb, gameobjectcache.wdb, itemnamecache.wdb, npccache.wdb, questcache.wdb.

3. My MacBook has the Cache/WDB/enUS directory, populated with the same files as the TBC Beta above.

I only have physical access to the MacBook currently, so I can't test creating the directory on the Windows box and see if it suddenly gets populated while playing. But given that it exists on the Mac and on TBC Beta, it seems likely that it would start seeing use, if it existed.

Good catch.

[edit: updated with TBC Beta directory info]

Hrm, yes I did notice that directory in my Beta client. I really do hope it is as simple as this.

Wodahs, major props. I went in game testing some other things, and someone mentioned their Alchemy tab never caching and it reminded me of this so we both tried it out. Sure enough, my FPS are up and his alchemy tab is caching.

Ha. Yes, I had noticed that my directory structure had a totally empty "Cache" folder now, but no WDB anymore (I noticed this since deleting my WDB is something I always do when DLing a major patch update, because I often get issues like naked players and invisible items if I don't). Good catch.

I only have minimal raid testing with this, but everything else is faster, so I am hoping raid performance is better.

Last night, having vid lag issues, I removed all mods, set graphics to low settings, and had 9 fps on patch, 1-2 at times during the fight. I am pretty desperately trying to find a fix here.

Yeah, I have been wondering about the empty cache folder every since they said that the WDB folder was removed and everything should exist in the Cache folder but mine was empty.

Excellent find.

Another confirmation, as soon as I made the directory it got populated with the usual cache files that used to sit in our WDB folders. I was wondering what happened to the stuff too , since many people were complaining of the "all white character model" /??? items etc.

Thanks a lot, fixed my FPS issues. Spreading a word now :)

Thanks a bunch! Helped me with my FPS issues a lot.

Someone posted this on our guild forum, don't know from where but it might elaborate on some things.

I assume that it would be Cache/WDB/enGB for euro english clients, frFR for french clients, deDE for german, etc?

edit: confirmed with a guildie in beta on enGB at least.

i can confirm that creating /cache/wdb/enGB gets the folder populated with
for the EU-enGB client.
Will have to see if it fixes the fps issues i had in Naxxramas tonight
