  1. very weird for these specs..
    Do you have all relevant drivers ?
    Gpu's well placed ?-
  2. Works fine, latest drivers, updated FSX. Now i got about 15 fps steadily after updating FSX
  3. Thats still not good -
    What are your temps, monitor with hw monitor..
    What games have you played and fps ?
  4. All these games maxed out:

    Killing Floor-60-80 FPS

    TF2- 100-200 FPS

    ARMA2- 20-60 FPS

    Empire Total War 25-55 FPS

    Napoleon Total War 25-55 FPS

    Left 4 dead 2- 60-65 FPS

    Mostly I get 60fps in my games

    Temps are ...

    CPU Temp: 16 Degrees Celsius 60 in Fahrenheit

    All the cores are around 34-37 Celsius
  5. Have you applied all the patches for FSX? FSX is very processor bound and the original .exe only supported a single core. The patches enable support for multiple cores.
  6. I believe the highest update is SP2 correct? thats the highest I went
  7. This topic has been moved from the section Video Games to section Graphics & Displays by Saint19
  8. You can try With the latest patch available from developers website-
  9. as stated above, it's very cpu intensive, have you tried overclocking your 920? What resolution are you playing at?
  10. no, have not tried overclocking although i have watercooling, i play at 1024x768 but i will be getting a monitor for christmas that supports 1920x1080
  11. Full screen, right? That's insane for that low resolution.
  12. so what do you think is the problem?
  13. I can't think of any logical reason. Have you tried uninstalling and uninstalling fsx? Are you trying a crazy AA level or something?
  14. highest AA but thats it, uninstalled it yes
  15. i have this system n when i install addon like pmdg n ultimate traffic n rex my frame rates drop
