Im running into some huge performance drops in my raids anymore, and I cant seem to track down the issue. Framerates dropping to 10 or less on several fights, especially Sarth with even 1 drake. Currently, Ive been running with everything maxed, and yes, I can see how I could avoid this by turning everything down. However, with my current specs, I really dont think I should be forced to run the game at low settings, making the textures muddy, and generally looking like ass.

Current specs

Vista Home Prem - Fresh install as of last night
Athlon FX-62 cpu
4 Gigs of DDR2 Ram
8800 GTX
75g Raptor 10k rpm HD
Abit AN9 32x Mobo


Im wondering if anyone else is running into issues of the sort, and/or may have know some tweaks to get the most of this system on WoW? I mean really, its a bit of an overkill for the game. No idea why Im having the issues.

Currently nothing like that. In fact, tonight it was pruned down even more than normal, due to it being a fresh install. Decursive, xperl with no 3d portraits, bartender, and buffalo are about it. I dont have a memory mod installed, but going by what Ive noticed before, Id say the whole thing is coming in WELL under 10mbs.

Ill keep tweaking things, and if I find anything mind blowing, I'll share.

Two major issues that people have brought up numerous times recently:
- Combat log issues. Try reducing the amount of things in your combat log, or making filters which show nothing at all. Generally this tends to help with disconnect issues, but it may help your framerate too. edit: -> see posts 12/13 of this thread.
- Death and Decay. Do you have death knights in the raid, and if so are they unholy spec? If they are, they almost certainly have Morbidity, which has been linked to major framerate drops in combination with the use of Death and Decay.

Further general things:
- Are you running in windowed mode+full screen? You may want to try with full screen rather than windowed mode/full screen, as it (generally) improves framerate a lot.
- Do you run many things in the background that you don't "need" for WoW, such as Steam / IRC / etc? It may be worth disabling them during 'heavy' fights (sarth3d and similar). I've found that this is especially true of websites with lots of flash animations, they can impact framerate a lot.
- You can hover over the default options button in order to see memory usage/etc of mods.
- Task manager is your friend - you can see how much memory/etc each process is using. I've found at work that if I leave my PC for 5 minutes after logging in, that everything runs much more smoothly for the day due to how the virus scanner seems to be acting.

Edit: Update your graphics drivers if you aren't running the latest official versions.

I have the same issues, out of combat is ok but once we start combat Game goes into praticaly slideshow 22fps with frame skipping, mode and this on a Intel Quad Core 9450, 4GB of ram and a ATi 3870 this happens mostly in Naxx25 and Obsidian in Malygos is fine tho maybe cause its such small instance.

In my opinion there is a severe case of bad implementation of Naxx in WOTLK. SWP runed 50fps+ in combat with my system on everything maxed and SWP is way more graphical intensive than Naxx.

There were issues like this at start of TBC aswell with SCC if anyone remember, the instance was such a FPS killer, Blizzard fixed it tho, it was a LOS issue cause the render engine was drawing all instance when it shouldnt, I think there is the same problem with Naxx in Wotlk.

I just noticed that Juravieal and me are both running Xperl gona try to turn it off during next raid and see if I get better FPSs.

Maybe slightly offtopic, but as far as I know, Omen doesn't process the combat log anymore. It just takes the threat values Blizzard provides (hence no more AoE threat display and so on).

25-man performance issues are a real problem and it seems to be one that may be caused by the game and not by hardware since Blizzard has acknowledged the problem and is working to improve it.

Something goes sometimes very wrong deep down in the code of WoW. Take my story for example. My system (2.4Ghz OC Core Duo, 4GB RAM, 8800GTS 640) faced a major FPS drop since WotLK. Some weeks ago I swapped my OCed Core Duo out for a Q6600 Quad Core since I use my PC for professional work, too. I did not expect to run WoW faster since the Q6600 has a clocking of 2.4 Ghz by default (same as my old OCed Core Duo).WoW, however, now runs at full speed again. The two additional cores can't be the reason since WoW doesn't utilize multi-core systems very well.

WOW dont use more than 2 cores you can see that in the Task Manager, he forces only affinity for 2 cores, even if you force 4cores it doesnt make any diference in FPS, and next time you run WOW the game will set affinity for only 2 cores.

I've heard a few people mention this now and I'm interested to know just how exactly this solves anything. Whatever ~filters~ you add to the combat log, all that data is still being received by your client. You can't just turn that off, the WoW client is still processing each combat event as it arrives, the filters are simply saying "don't display this", which as far as I can tell is no different then simply hiding your combat log behind another chat frame (as the default WoW setup is) which just doesn't render the log text until you make it the active tab. I don't see how filtering the combat log could possibly improve frame rate to any observable rate.

Thinking about it now, I would assume that the actual fix is to remove all filters, and have a base combat log that picks up nothing. By picking up nothing it's processing less (no) data, which should help. :shrug: No idea really though, but if it helps, it helps.

What power supply are you running for that 8800 GTX?

Be as specific as possible with the model number if you have it.
