Is my Gigabyte GTX 660 ti being bottlenecked by something?

I get unbelievably low FPS (40 max/20 min) in World of Tanks @ MAX.
This PC is brand new, I just built it yesterday.

Specs:
Processor: AMD FX-8350 Vishera, running @ 4.1ghz
MB: Gigabyte 990fxa-ud3
GPU: Gigabyte GTX 660 ti 2GB DDR5
PSU: Rosewill Xtreme Series RX850-S-B Power supply - 850 Watt
RAM: 16GB (2x8GB) G.Skill Ares 1866 - Manual set timing to factory | 10-11-10-30
(Running @1600 due to BIOS problems accepting 1866- Any help with that would be wonderful as well)
OS: Win 7 Home Premium 64bit

Running all my games @ 1366x768 resolution.

What I've done:

Fully updated all drivers for motherboard/gpu
Updated BIOS, etc. while trying to fix my 1600-1866 ram speed issue.
Spent hours googling for similar problems without any luck.
Turned everything to Performance in NVidia control panel, as well as turned off VSync in-game & on panel.

    I don't think the CPU is the answer, its more than capable of handling the GPU :/
  3. It's the only thing in your list that is sub-par.
  4. World of Tanks has been known to choke on some high end pc's but it is mainly the fault of the drivers like here

    http://ftr-wot.blogspot.ca/2013/02/wot-and-nvidia-drivers-v-31407.html.

    and here http://forum.worldoftanks.com/index.php?/topic/214555-84-terrible-fps/

    Try using older drivers like 306.xx http://www.nvidia.com/object/win8-win7-winvista-64bit-306.97-whql-driver.html

    Also, mind telling me your IGN in world of tanks? I'll help you more later if you want.

    Thank's for the advice, my IGN is _dipstick
  6. The AMD CPU is fine for most games but not WOT

    You need to OC the CPU more since WOT is stupidly single threaded. Even a stock i5 would bottleneck an 660ti
    I hit 100% usage on 1 core while the rest idle, GPU at about 70% usage, latest AMD drivers and all that

    Running high preset on my sig rig 1080p 50fps+ min

    Due to me just building this PC yesterday, I still have the stock heatsink because I didn't think I would have to OC this setup to play WOT. What would you recommend as for OCing with the stock heatsink, if at all?

    I would avoid any OC for now or only a very light one 4.3ghz?

    I had a 2ghz phenom II n930 + 5650m and @768p medium the cpu was bottle necking my 5650m 50% gpu usage and only 30fps ish

    Any setup on earth needs an OC to play wot 50fps+ :P They really need to get more load onto additional independent threads


    I would say you got an driver + OC issue since even my Phenom II x4 N930 @2ghz didn't have that many issues
  9. download coretemp and Gpu-z

    http://www.alcpu.com/CoreTemp/php/download.php?id=3

    http://us1-dl.techpowerup.com//SysInfo/GPU-Z/GPU-Z.0.6.9.exe

    And post an image to us like this or tell us the cpu and gpu usage



    Also, why does i7 3630qm at 1.6ghz + nvidia 650m run WoT faster at 1366x768? Is the FX-8350 that horrible at a game that uses one and a half cpu cores?

    I would say he has an driver issue or even another issue playing it's hand here

    my PII x4 n930 at 2ghz and a 5650m runs WOT a bit faster at high for 1366x768 on my laptop

    Your i7 3630qm also should turbo up to 3.4ghz :P
  11. Temps don't seem to be an issue
    CPU is loaded all the way up on 1 core all the way

    I would say an driver issue is your biggest culprit. Or some unknown issue with some random program in the background.

    Try a light OC to see if you get a bit higher fps to see if the issue is with the CPU

    I took the advice of shotgunz, and downgraded my gpu driver to 306.97, no change in FPS

    Try a light OC as well as testing out different levels of quality
  14. You may want to lower your settings. Max settings is not an easy task.

    What AA level do you have it set to? Anything beyond 4x MSAA is asking for trouble.

    Only AA in WOT is FXAA LQ, MQ and HQ

    He could ahve used hardware AA i guess

    My AA was turned to HQ, I set it to Off and Low without any FPS increase

    Can you check GPU usage? If lower graphics settings does not improve FPS, that is a big sign that your CPU is a bottleneck.
  18. My GPU usage is at only 17%, proving that the way WoT is ran, from one core, is bottlenecking my GPU. Is there any way around that short of OCing?

    His GPU load in his screenie earlier is about 19%, that is to be expected though for 1366x768 (I only hit about 70-80% on 1080p high on a 7850)

    In either case it is a bottleneck. And his resolution difference should at most halve the usage. When you drop the resolution, it does make you hit the CPU cap easier than at higher resolutions. It just happens that his cap is very low.
  21. It's just weird that his cpu is such a limit when much weaker cpu's have about the same fps
