CPU bottleneck? 35 - 40 % usage during witcher 2

ok to start off these are my specs

gtx 680 2gb

amd phenom II 1090T x6 @ 3.8 ghz

8gb ddr3 RAM

700W power supply

So, I noticed a problem where my game would run at 45 fps during intense combat, but then in certain areas my fps would drop to 18 when looking at a certain angle

an example of this drop would be

- next to the roses of remembrance, looking down at flotsam.
- during the prelude to the ghost battles in the second chapter, looking at the burning battleground.

So i noticed in this game my GPU usage is only used up to 50% MAX . When the intense fps drops arrive my gpu usage drops to 32%

it's crazy. people have told me it has to be a CPU bottleneck, but im not too sure about that because I have only had FPS problems with this game so far. My rigg handles everything else i throw at it.

And for comparison, when i max out metro 2033 my gpu usage is 75% minimum.

> all my drivers are up to date
> I do not have ubersampling enabled
> I tried uninstalling and reinstalling the game three times
> V sync is disabled


This is driving me crazy.

Does anyone know what the problem could be? Thank you in advance.


Also....


If this IS a cpu bottleneck, what CPU should I get? My motherboard only supports AMD, sadly...

  1. Updated the game to the latest? few of the first one versions of the game were crappy and had bad performance issues. Also possible it's just a crappy sort of coded game. Happens a lot that even the best of systems can't handle.

    Yeah its completely updated. Its a shame...

    I also had the same problem with my AMD 6870 1gb
  3. The best way I've fuond to see if it's CPU is just to do an antialias test, run through fraps and record your frame times. Then turn on anti-aliasing and look at the frame times again. (you can use just the min/max/average numbers too).

    If you notice that your min/max/average all drop by similar percent amounts then it's your GPU. If you notice your Max and average drop, but your minimum numbers stay pretty much the same, then the times that are slow your GPU is waiting around on somethign anyway so it can't make frames. . . that mean CPU.

    If you look at frame times as a chart you will notice spikes in the slow down areas (longer frames) and those spikes won't change, but the average, and especially the really fast frames, will slow down when you turn on anti-aliasing.

    Alright so after doing that my avg and max increased a tiny bit with it off, but my minimum stayed the same either way.

    Soo it's the cpu I guess...but whats the deal? Why is this only happening with the witcher 2?
  5. Probably just a lot for your CPU to do, like high mesh scenes. The same kind of things happens in lots of MMO's when tehre is lots of stuff around.

    Every MMO I played is fine with this tho...

    Is there any way to fix it?

    Other than overclock more or get a faster CPU, not really. By faster I don't mean more cores, i mean actually faster for the games you want to play. Take a look at this CPU scaling chart for The Witcher 2 . . . http://www.techspot.com/review/405-the-witcher-2-performance/page8.html

    There is a reason far more people choose Sandy/Ivy bridge for gaming rigs.

    I pretty much gave up on it. it's not worth my time. If this is the only game in my whole library having problems like this, well then the game is unoptimized shit. Specifically speaking the Enhanced Edition is unoptimized shit.

    If i can max crysis 3, bf3, metro 2033, saints row 3, and many more dx11 titles without a problem, then there is no excuse for the witcher 2.

    I have never had a problem like this outside of the witcher 2, and that tells me something.
