Issues with random fps in world of warcraft

post #1 of 6
Thread Starter 
Not sure where I should post this, so thought I would do it here.

First of all this is my system:

http://valid.canardpc.com/show_oc.php?id=2264662

Graphic drivers is: 295.73

I also did a clean install of the new drivers, where I cleaned regedit etc.

Issue:

When I play world of wacraft (Yes, I do play other games than that as well), my fps seems to be very random. It can be a constant 60 fps, but then all of a sudden it will start dropping to 30 fps then to around 23 fps.

I have checked the in game settings to see if anything is holding it back like fps limiters, but I have taken those off and it still does the same thing. Sometimes I can get it up to 60 fps simply by tapping out then in again, but as soon as I look around it starts dropping and being random again. The same happens when I switch from "primary monitor" to "monitor 1" and back again in the WoW settings. I only have 1 monitor btw.

The refresh rate for my monitor is 60, and I have made sure that it is that in WoW, nvidia settings and of course the monitor ones.

I really don't know what could be causing this at all, and I have tried a few things to remedy it, but it keeps persisting, so perhaps some of you know it is, or have an idea to solve it.

Thanks

Do you have a system monitor open to see what your CPU and RAM usage is?

What are you doing when you notice the drop? Any specific things on screen? Raids, dungeons, populated city? How is it out in the world with nothing else going on? The biggest hit I've seen is some of the smoke or haze effects causing a pretty substantial hit in performance.

WoW isn't really the best coded game as far as performance goes, though there is a lot of dynamic stuff as well. Population in the zone, even if not on screen, can affect the performance. Dalaran for example, used to also render the world below the city, causing some major performance hits when it was populated. I don't know if they ever fixed that.

I used to play WoW myself and have had some of the same issues.

The problem with WoW is that it a very outdated game engine and is heavily CPU driven and does not maximize your GPU. When I used to play it on my 570GTX I noticed some sudden drops in FPS at times and it turned out that my card was 2D clocks at times(425Mhz core). I used MSI afterburner to monitor the clocks on my card. It would spike between 3D and 2D clocks at times causing stutter/lag.

It has something to do with the power management settings What I did to fix this was to go into the Nvidia control panel and set up a profile for wow.exe. Under power management, instead of "Adaptive" select "Maximum performance" Make sure you reboot after you do this. (If you want, you can force this power mgt setting to maximum globally)

Turing your graphics settings to maximum to force your GPU to run at 3d clocks helps but I found that adjusting the power mgt settings to work much better at forcing WoW to use 3D clocks.

Their Direct X 11 (not really DX 11 lol) in the game settings can also help WoW use more of your GPU and get better frame rates but it was always buggy for me which resulted in more client crashes.

hope this helps.

v-sync(or whatever nvdia equivalent is!is probably enabled!also for the low fps remember this in shaded area (like cave,wood etc)your fps will drop (stay in the sun)

I'm currently trying out what you said and so far it seems fine, but will let you know if anything changes of course. So far a big thanks smile.gif

To the others about performance issues it really shouldn't be there in WoW with 580 gtx in SLI, where I can run BF3 in full detail with full fps. This is why I found it odd that it behaved like this in WoW when it isn't exactly a game which is more demanding than BF3.

EDIT: Been working great, although after 30 minutes or so I got a driver crash. Make that multiple driver crashes now.
