1) full system specs (new build):


  • make and model of the motherboard - ASRock Z87M Extreme4 LGA 1150 Intel Z87
  • power supply - Coolmax 240-Pin 900W Power Supply with Active PFC (ZU-900B)
  • SSD - Samsung Electronics 840 EVO-Series 120GB 2.5-Inch SATA III Single Unit Version Internal Solid State Drive MZ-7TE120BW
  • HDD- Seagate Barracuda 2 TB HDD SATA 6 Gb/s NCQ 64MB Cache 3.5-Inch Internal Bare Drive ST2000DM001
  • Memory (Set up Dual Channel in A1/B1) - G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL
  • NVIDIA Drivers - 331.82 and 332.21
  • OS - Win 8/8.1
  • Video Card - PNY 770 GTX 2gb plugged into PCIE1 (monitor is plugged into the GTX via HDMI)


  • 2) Full description of the issue:

    I'm trying to game at 1920x1200, trying to play both BF4 and Far Cry 3. NVidia Experience indicates I should be able to play these on High/Utlra. This proved very quickly to be false, and I dropped the graphical settings very quickly to low (AA off) on both games, which has made little difference.

    I'm able to sometimes run decent framerates (60-100) as soon as I start a new session of BF4, but they are very short lived, and I'm in short order running in the teens or worse. FC3 is no better -- I cannot even have an engine rendered cutscene play smoothly. I don't know the setting to doublecheck my fps in FC3, but to my eye it's maybe 30, then stutters under 15-20, and goes back and forth.

    I see similar results in Uengine Heaven benchmarking (particularly with AA on), but with a better base frame rate (go/stutter/go/stutter):

    Heaven Benchmark v3.0 Basic

    FPS: 61.2
    Scores: 1541
    Min FPS: 9.0
    Max FPS: 141.7


    3) Attempted resolution steps

    - Updated driver firmware
    - went from win 8 to 8.1
    - reduced graphical quality to low
    - checked process monitor to make sure there weren't any competing resource hogs/startup items
    - checked power management, disabled energy saving on the GPU and set CPU minimums to 100%
    - installed EVGA precision and set a target FPS
    - confirmed Ram is in DC config, the 770 is in PCIE1 and the monitor is plugged into the 770.

    I'm at my wit's end here. Any help would be appreciated. I have a worthless $1,100 computer right now. I'd rather keep the hardware if there's an available solution than ship it back -- if you fix the issue I'll paypal you $20, dead serious.

    tl;dr can't play games on low that I should be able to play on high/ultra

    Have you overclocked anything? Run the on screen display that precision x provides and see if CPU and Gpu are running at 100% in game. This sounds like a psu or a ram issue.

    Can you monitor your GPU temps? It might be overheating and throttling itself back.

    No overclocking done, no. I don't understand how either could be pegging at 1920x1200 on low with no AA?

    How do I go about checking to see if there's a PSU/RAM issue?

    This happens straight from cold boot. I can't imagine there's time for temps to get that high? I can boot, go to Heaven Benchmark and immediately see the stuttering right from the preview.

    Try the GPU in another PCIe slot. And it's worth checking the temps, you never know lol

    To check the PSU, you would really need to borrow another one. What CPU do you have? You can try using the integrated graphics to see what that does.

    One way to check the PSU is with the Logging function of HW Info64: http://www.hwinfo.com/

    The program defaults to log a plethora of otherwise unneeded information at a 2 sec interval, which is pretty long for monitoring voltages.

    Go into the "Configure Sensors" menu and just pick out your voltages that you wish to monitor - especially +12 v. and +5 v. Set the monitoring interval to 250-500 ms. Start monitoring and start your game. Monitor it just long enough to see some of your problem artifacts because you will be saving a lot of data. Open the data in MS Excel, or the open office equivalent and check for wide voltage swings.

    Good luck!
