Hello everyone,

 

I have a big framerate issue in fsx. I have a pretty good system but can barely run at 30 FPS with all the sliders near zero. Can someone avise me if my system has a nottleneck somewhere that is causing this? My specs:

 

Intel Core i7 Quad (with hyperthreading) @ 3.5 GHZ,  Nvidia GeForce 8600 & Nvidia GeForce GTX660, 2*500GB Seagate Hard drives, Asus Sabertooth Z77 motherboard, Corsair Vengence 2*8GB DDR3 RAM

 

Thanks,

 

Matthew

This is normal.  When you lock your FPS at 30, you hope it will stay there during most of the flight but it's nearly impossible to maintain 30 fps because of various factors such as commercial scenery, commercial aircraft, time of day and real weather.  If you have all of your sliders to the left then you'll have graphics anomalies and your FSX will not look very good.  Even at the default settings (the settings FSX provided you when you first installed FSX and ran FSX for the first time) are better than all the sliders to the left but it will also produce anomalies. When you are flying at FL200, you should be getting at least 60 fps even in a commercial aircraft.  As you descend and land or takeoff at a commercial airport, your fps will easily drop to near single digits. Pinned at the top of this forum is the excellent AVSIM Software and Hardware Guide which is constantly updated.  It provides some settings and tweaks you can employ to make fsx run better.  The settings and tweaks do not work for every system, especially the BufferPool tweak. 

 

Hope you have better success after setting up your FSX and display driver settings via the AVSIM guide.

Thank you Jim,

 

After using the guide you mentioned, I have hugely improved my FPS and my sliders. Now most of my sliders are near the middle (exept traffic) and I get 28-30 FPS on the PMDG 737 NGX. I really appreciate your help.

 

 

Cheers,

Glad it is working for you Matthew. There are some really good suggestions in the guide. That sounds normal with the PMDG737 and 28-30 fps is really good in FSX.  You are just going to have to accept the periodic frames going into the teens once in a while.  I occasionally get one digit fps but it is only momentarily and not really an issue for me.  At least it does not crash to desktop and the flight still is relatively smooth. 

 

You only indicate you have an I7 CPU installed.  Which one?  The 2600K?  The 3770?  If you have the "K" at the end of it, you can overclock your system a little and maybe get a few more fps.

Jim,

 

I have an i7 3770K and I do plan to overclock it. My main concern is my 500 watt power supply. Do you think it will be sufficient to bump my CPU up to 4 GHZ?

 

Regards,

I recommend at least a 750 KW or higher for overclocking.  They are being made better though but, if you are going to upgrade the supply, get at least that wattage.  I have my CPU oc'd to 4.4GHz and see no reason to go higher.  I had it at 4.8GHz for a long time but had periodic BSOD's so lowered the oc and haven't had any BSOD's since.  In the AVSIM Hardware Forum you will see some settings people used for overclocks and many discussions on this topic.  I think you can even find some suggestions for your 3770K.

 

Best regards,

Jim
