I have what I consider to be a mid-high end computer and the specs should allow FSX to run smoothly, or so I thought.
The problem is that whenever I start a flight, the FPS is around 30 locked at add-airports (50 unlocked at default airports). But then it steadily decreases to the 10s and sometimes below 10 after 15 minutes or so of flying (I may sound a bit spoiled, but I need these frames as I run a FSX YouTube channel).
Here are my specs:
MB: ASRock H97M Pro4
CPU: Intel i5-4690K Haswell overclocked to 4.2GHz
CPU Cooler: Cooler Master 120V Seidon
GPU: EVGA GeForce GTX650 1GB
RAM: 8GB (4GB x2) DDR3
PSU: Dynex 520W
As you can see, my computer should be able to handle FSX well, but for some reason it's not. I've tried a clean fsx.cfg, defragging the hard disk, using the Nvidia Inspector settings, and lowering cloud and water settings on REX4, but none of those fixed the problem.
What do you guys think is causing this problem? Hardware bottleneck? Improper software configuration? Any input would be greatly appreciated.
Thanks in advance.
