Tailspin45 Posted April 12, 2017 Share Posted April 12, 2017 Talk about a love-hate relationship! I love flying around my San Diego stompin' grounds, but I hate the horrible frame rate. Suspect I've done something wrong, or something happened during install, I'm not blaming ORBX or Matteo to be clear. But I haven't found a solution and FSX is unflyable. My I7 4.2Ghz GTX-580 rig should handle it OK. In fact, before KSAN install I'd see 45-50fps with lots of AI traffic and cars, fog etc.. Suspecting texture issues I reset FSX to 30fps but that didn't help. One possible clue, for those who know more about these things than I do, is the frame rate is about 30 when the aircraft is sitting on the runway and I don't change the view. But start rolling or look around and it drops to 6 fps - this with clear skies, by the way - and then it slowly goes back up to around 30. Yes, I've turned everything down in KSAN; I even have zero traffic in FSX, mid-water, normal autogen. For the record running Win 10, FSX Gold, DX-10 Fixer, Orbx SoCal, TrackIR, SPADnext, AS16, REX Texture Direct with Soft Clouds. And yes, I did dig around in the forums here and Googled my brains out looking for a solution, but no joy. And no, I didn't change anything else; this occurred before the Win 10 update and problem didn't change afterward. Thoughts, suggestions? Link to comment Share on other sites More sharing options...
Richard Lincoln Posted April 14, 2017 Share Posted April 14, 2017 Hi, Thanks for posting in the Forum, my first thought would be to back-up the original cfg and let the sim create a fresh one. Could you please report back as to the settings you have selected in your control panel in FTXCv3? Link to comment Share on other sites More sharing options...

Tailspin45 Posted April 15, 2017 Author Share Posted April 15, 2017 That KSAN variability percent should be 16.3% not 116.3%, to be clear. Link to comment Share on other sites More sharing options...
Tailspin45 Posted April 18, 2017 Author Share Posted April 18, 2017 And OKC average shiykd be 30.1 not 301.1, but I suppose that is obvious. What;s nto so ibvious is why there have been no suggestions or replys. Did I say something wrong? Link to comment Share on other sites More sharing options...
Doug Sawatzky Posted April 18, 2017 Share Posted April 18, 2017 What happens if you uncheck/deactivate it in your scenery library? Did you open the DX10 fixer to trigger an element scan? Link to comment Share on other sites More sharing options...
paulb Posted April 19, 2017 Share Posted April 19, 2017 Hi, I am not sure if my comment helps, but I installed KSAN last week. My typical 30+ orbx frame rate dropped into the low teens at KSAN. I was not too surprised as I do find that large detailed scenery (typically very big airports) really slow things down a lot when compared with my usual bush flying in PNW for example. I have had a similar frame rate issue with the biggest airports in Australia. I have only flown at KSAN twice so I will need to go back and test it again. Re your comment about changing views and particularly looking around - as you will know, this asks your pc to load lots of new textures - hence the usual frame rate drop. It then takes a short time to load everything and speed up again. So that is not too suprising. One last observation - your GTX580 video card. Perhaps that is struggling with the demands of a large complex airport? I am wondering if it could be a memory issue? Cheers Paul Link to comment Share on other sites More sharing options...
Tailspin45 Posted April 20, 2017 Author Share Posted April 20, 2017 I tried disabling KSAN before posting here, Doug. Problem went away, so I knew it was something to do with the KSAN add-on. And yes, I had run DX Fixer. But thanks for the suggestions. They didn't help me but may be useful to others. Now running a GTX970, overclocked my mobo, and added back in every KSAN frame rate killer. Even the animals. And I'm a happy boy. Frame rates are acceptable running around mid-20s and no lower than 15-17 but still smooth with no glitches or stutters near the airport--and that's with low stratus weather, typical for the area. Paul's comments reinforce my discovery, and were helpful. Like KSEA, KSFO, etc. KSAN is demanding. But WOW! Link to comment Share on other sites More sharing options...
