NZFF

Hey guys,

I was wondering, instead of posting up on Facebook and getting flamed by a bunch of randoms from all over the world I thought I'd ask here.

So I have the following HW setup at the moment.

• AMD FX-8350 @ 4.5Ghz
• Coolermaster Sedion Watercooler
• 32GB DDR3 RAM
• Gigabyte GTX660OC 2GB
• 128GB SSD (OS)
• 1TB 7200 WD HDD (FSX/P3D)
• Win 7 Pro

The problem I'm having, is that I'm struggling to reach a mere 20-25 FPS in FSX. And I'm not too darn sure where the heck the problem is. I use procexp to find out what's using all of my resources, and I find that FSX or P3D is barely using my GPU, and that my CPU usage reaches about 70%, 60% is FSX/P3D. I mention both because I get similar performance on both.

I have the following addons all enabled. So I don't know if that's it.

• ASN
• REX4+Soft Clouds
• PMDG 737(FSX)/747(FSX)/777(FSX/P3D)
• Orbx - Global, NZ-NI, NZ-SI, AU, AU-YMML, AU-YBCS, ENG, SCO, IRE, NIR
• Uk2000 EGLL, EGPH
• Aerosoft Airbus 3XX X
• Aerosoft Amsterdam X
• FlyTampa St Maarten
• AUScene Sydney/Adelaide
• TropicalSim SBGR/SBGL/SAEZ
• LatinVFR SCEL/MDSD
• AES
• GSX

And I'm pretty sure that's it.. But what I'm finding is that I'm hitting a max of around 15FPS but mostly around 10FPS and below. Is it my hardware setup?

Hi Dorien, this is very much a standard issue when running FSX in a very hi density scenery environment, your hardware is well above what I have got , there are tweaks but generally it is a case of moving the sliders back, road traffic has a large hit on frames, maybe bring the Autogen sliders down a bit.

I thought about that, but my sliders are pretty much either all to the left with the exception of AI Airlines, that's 20% and GA Traffic is 10%, all other sliders, Road Traffic/Sea/Leisure Boats are 0. And airport density is Low.

Auto Gen Scenery/Vegetation/Buildings are all on Normal. Will drop that to sparse and see what happens...

To me that dose seem the PC is under performing , 'I was guessing all your sliders were all the way to the right' , maybe have to wait till later tonight for others to compare, the sparse look you wont like but it would interesting to see how your frame rates pickup.

Yes, it does look like there's a problem somewhere. I have a very similar system, except it's an Intel i5, and I only have a GTX 650ti. Although I don't use any flash addon airports, I get 30 -- 50 frames with most settings all the way up.

One simple thing you can try -- since sometimes the cfg can get 'stuck' pointing to older drivers when you update, you could try just deleting your fsx.cfg and let it rebuild.

You're using an AMD kill it, kill it!!. Just kidding, not gonna start that war up again.

It could however be part of the problem. I say that because you have it coupled with an NVidia graphics card. Whilst you have a good APU and a good GPU FSX relies more on APU/CPU than it does on your graphics card so coupling an AMD APU with an AMD GPU that works in symbiot with that APU would p[possibly yield better performance results because they would both boost each others performance in certain areas. This is why I stay away from AMD and just go with the Intel/NVidia combo personally because they run by themselves without looking for a boost from something.

2 other things of note is Aerosoft Amsterdam and the PMDG 777, couple those 2 together and you are not going to get a great frame rate at that airport regardless of how your sliders are set. It is a complex aircraft and a hugely complex scenery and some of the ORBX ones will clunk your frames a little too. The thing to remember is the more you have running, the more you will drop your frames.

Here's an example, I fly into Heathrow and I have the following for the area.... Aerosoft London VFR & Heathrow Extended, UK2000 Gatwick/Luton/London City/Stansted, ORBX England/Vector/Global, Rex 4 and soft clouds and full AI traffic and I get between 5-8fps or an OOM and I have between 10-15fps for the other airports mentioned there.

Have you tried Bojote's Tweak

you will find it may help with your fps

I'm curious about your stated CPU loads. When you say 70% how is that load spread across your cores?

You might have one core pegged 100% and the others mostly idle - which is what you'd expect from FSX being largely single threaded - and it could well report a *total* CPU loading of say "60%".
