weird FPS issue.

[B@nj0 P3do]

so basically, my FPS is acting really strange in one certain Display mode, namely Windowed.

Fullscreen mode: 60 fps
Windowed mode: 58fps
Windowed mode, with all corners out in the edges: 11fps
Windowed mode(fullscreen): 58fps

when I have it in windowed mode, with all the corners on the edge of the screen, GPU usage drops from 63% to 10-11%

Images showing what I mean between windowed mode and windowed mode with all corners in the edges:
Windowed:

Windowed mode, with all corners out in the edges:

this started happening today, cant understand what the problem can be

Probably your computer drops 3D acceleration off for some reason when you're running the game Windowed. Have you done something with drivers lately, or tweaked windows or graphics card power features?

I upped the Overclock from 900Mhz to 960Mhz, but that is the only change.
I dropped them back to 900Mhz and it was still acting up

Edit: Stock and still acting up

I must say I have never encountered this, but you can try Blizz tech support and see if they have any knowledge about it. If you have altered or installed some new programs lately they may cause what vesseblah said, my brother had a sudden fps drop when he let our cousin use his pc, turns out he installed some shit and just clicked away on the shiny buttons that lead to install. Most likely I'm wrong, but there is a slight chance.

Also love your avatar!

I managed to get Metro 2033 for free, added to steam and then Steam removed it (from my steam list, can still play it) since it was not ment to be free (nvidia screw up).

But I really doubt a game beeing removed from steam can cause WoW to behave like this in a certain setting =/

I will make a post on the official Wow-europe forums though

Still having the problem, help would be appreciated please

I know that can happen if the Windowed mode size was adjusted without setting the display resolution.

Unfortunately WoW does not have the adaptive resizing ability EVE Online has, where the game adjusts its resolution to the window size (So resolutions like 1099x987 are completely normal in that game). This means that WoW instead has to manually get the processor to recalculate the appearance of every single frame because they all need to be rescaled; creating an absolutely massive performance bottleneck.

If you can - try and find a way to reset the Windowed mode size. Start by setting another resolution for example.

why is your fan speed on min? what are your temps?

Unfortunately WoW does not have the adaptive rezising ability EVE Online has, in which it fetches the window size and adjusts the game resolution to fit that.

I'll give that a try when I get home (sent form phone)

I have watercooling on my PC, so nothing is connected to the Fan connection on the Graphics card

Temps are a wopping 40-42 celcius max on the graphics card, and 60-62 celcius on the CPU

Happens to me on Nefarian but its even worse. I run WoW on Ultra High (shadows on normal because it looks bad on high) and when crackle happens I get around 1fps ... I seriously doubt its my PC specs since they are more then fine for WoW (cpu kinda meh but its decent 4.0ghz clock at), my guildy also experienced this....

Made a ticket to GM.... Also running Window Mode (fullscreen window mode)...
