Hey guys,

I am currently running an i5 3570k @ 4.4ghz and getting around 25 - 30 FPS on the ground / low altitudes and well into the 40's in the air. My question is if I overclock to a higher GHz, will the performance increase? My PC Specs are as follows ...


i5 3570k @4.4 GHz currently sitting around 63 degrees celcius on 100% load.

EVGA GeForce GTX 650 Ti Boost @ 1200 MHz

8 GB Corsair 1600 MHz RAM

Cooler Master Hyper 212 EVO

600w CX600M Corsair Power Supply


I am using FSX Acceleration pack and the addons I run are REX+, PMDG 737NGX, Airbus X Extended, UTX, and some airport scenery addons. I am looking to pick up Ground Services X and I have heard that was pretty frame rate intensive so I wanted to make sure I could run it before I bought it. I do fly on VATSIM sometimes so the traffic sometimes lowers FPS as well.

My fsx.cfg is tweaked pretty well I would say so there isn't much improvement there. Also, would overclocking the ram add any improvement?


Thanks for any help,

overclocking the CPU is most important and will allways give some more fps and smoothnest in FSX. Some experts say that the best range to run fsx is at 4.5 - 4.8GHz or higher. From there begins fun :)
