im playing at a Intel i7 920 system, with 6gb trichannel ddr3 memory, even so.. i still think a whole lot about my gaming performance and the grafical enviroment. tho, still need to find a situation of lagging due to fps:)
Addons that add colors to abilities when out of range can be quite a CPU hog (Buttonrange, Redrange to mention two).
I'm no lua expert, but I think I read somewhere that it has to do with the way the frames is updated (and how frequent it does this).
This is an good example of addons being lightweight in the memory department, but using quite a lot of CPUtime.
AddonProfiler appears to be broken... for any reason it does not show anything. Tried different time frames, different scenarios (e.g. ooc, infight, party, raid, pvp) but after the testing period there are only "--". Need help
Old computer, 1gb memory, broken video card with no graphics acceleration that can still somehow push 1920x1200, and I have no issues from addons. Memory has never been a concern.
Badly coded addons are a concern. Don't use unmaintained fringe nonsense. Don't have unnecessary addons loaded for critical things like raiding.
Unload addons with option house:
Use addonswitcher to change profiles quickly:
Get dynperf if you have fps issues:
Buy a decent SSD if you are thinking of spending money. Yes, it will let you visit Dalaran without being horrified by the lag.
Addon memory used to cause lag (Vanilla WoW era). The Lua scripting system would garbage collect (GC) addon memory, every once in a while go through everything stored in addon variables and check to see if it was still being used. If not, it would clear out the space for future use. With lots of addons using lots of memory, this took a noticeable amount of time and showed up as brief lag. Lag in the middle of Blackwing Lair was bad. I even had an addon that would trigger GC that I would run before combat. TBC introduced a new continuous GC process that broke the job into small bits so you never saw noticeable lag from GC. Unfortunately the myth persists that addon memory = lag and people to this day use that as a measure of quality of an addon.
That isn't to say that addons won't cause lag and many posters in this thread have already pointed out some that do. Any addon that looks at incoming combat messages will slow down in AoE. Addons that try to do big chunks of work every frame drawn on screen will also cause framerate issues. Addons that try to communicate with other people running the same addon can also cause issues.
The above mentioned OptionHouse will also profile addons for CPU usage, you may want to try that to see which addons might be impacting framerate.
when i looked att the fury warior movie from tankspot i got todaly sold.
i maked one warrior and start to lvl 45 then i start to look after some cool/good addons.
I whanted the cool range thing on midle of the scren in the movie. and i think its iceHUD right =??? so i tryed it and it will not work thee wey i whant it to....
