Thread: Best FPS for FSX

  1. Default Best FPS for FSX

    Hi! I need help to boost my FPS in FSX in my computer. Is there any way to have high FPS possible with lots of scenery without killing the FPS?

    You want at least a dual core CPU capable of overclocking to around 4.0GHz or better. A recent i5/i7 Intel processor is best.
    You want a CPU heat sink capable of allowing your overclock.
    You want a robust motherboard compatible with your other components and configurable for overclocking.
    You want at least 4GB of fast RAM capable of allowing your overclock.
    You want a Hard Drive that spins at 7200 RPM or more with SATA III conections or better, an SSD (Solid State Hard Drive) is ideal provided it is large enough for your operating system install and foreseeable FSX/Add-ons install.
    You want a Graphics Card (GPU) equal to or better than a Nvidia GTX 460 with 1GB VRAM.
    You want a quality Power Supply Unit (PSU) providing 650w or more. Do not skimp in this area more is better, quality is very important.
    You want Windows 7 Home Premium 64 bit or better (Professional,Ultimate).
    You're welcome!

    That is a very broad question.
    Unfortunately with flight simulators, there is no such thing as a free lunch - high visual detail comes at the cost of high processing power.

    There are an infinite number of tweaks, settings adjustments, and other things which you can do in order to squeeze more performance from the simulator. Far too many to detail in this thread, in my opinion. Do some browsing both here and at other flight simulation forums, and you will come across hundreds of ideas, tips, and changes which you could theoretically make. In my experience, even with the most profound of tweaks and tips, you will always be compromising something for performance.

    Personally, I do not do any of the extra legwork to tweak my FSX installation except for changing the settings which are built right in to the simulator itself.

    The only other tip I would recommend is do not look at the FPS indicator and use that as a judge of performance. Use the experience as a whole, without the FPS counter, as your guide. Who knows - you may unexpectedly end up happy with an FPS level lower than you might think, allowing you a higher degree of visual detail!

    Good luck!

    I agree with greggerm. If you pay too much attention to the FPS counter, it'll screw with your head. Sometimes with video cards and older game platforms like FSX, bigger and badder ain't always better. I have an ATI Radeon 4600 series and I average 15 to 20 FPS with default planes in JFK with scenery complexity maxed and autogen set at very dense with cumulous clouds starting at 5000 feett up to 20000 feet. I have very few tweaks done in the FSX cfg. Most everything is maxed except the mesh resoltion and mesh complexity. I just have a quad core 3.0 ghz machine with 4 gigs of ram.

    Just imagine what you would get if you did tweak your system then Peter. Your system is way better than mine and I'm getting better framerates than you are a Heathrow with VFR Real Scenery.

    (Mind you, I've wasted hours and hours on tweaks that don't work as well as those that do).

    Imagine; you could be having fun with stutters and CTD's and then enjoy spending more time tweaking rather than flying.

    Try turning off unnecessary Windows background tasks for better frame rates. There are a few applications (some free) which will shut down task not necessary for FSX.

    I decided to set up a stand alone PC ONLY for FSX and only having Windows and FSX installed. Not even Virus protection software (can't see the point if I'm not downloading anything just running FSX).
    I do everything else including internet browsing and downloading on my second PC which doesn't have to be fast. After downloading anything for FSX I scan for virus's and then if clean transfer to my 'FSX' PC.

    I only have a CORE 2 DUO 3.0 Ghz CPU, 1GB video card and 4Gb RAM and get frame rates over 50 with scenery etc complexity set around mid way.
