Unusable frame rate on high end PC.

Recommended Posts

Hi all, I'm new to AVSIM, but not MSFS, so forgive any errors in my forum edicate. :blush:

 

What, I'm facing here is NOT your average frame rate issue. I've read and read and read about people having problems keeping their frame rates above 30, but a huge percent of those are old, outdated forum posts where the user was still using a sub-3GHz CPU and only 2GB of RAM on a not-so-high-perfomance motherboard.

 

I understand FSX is highly CPU intensive, and seems to have a nasty habit of 'ignoring' your video adapter's graphical processing capabilities. I'm estranged that it doesn't call on the processing power of CUDA  in nVidia GPUs, since 'traditional' processing is so important to it.

 

Anway, what I'm facing here is an almost definite 14FPS when the G1000 is turned on and the engine is running. I have managed to reduce a few settings here and there and use a frame cap to keep everything at 30FPS (I run everything else at 60FPS), which is absolutely fine for flight simulator use.

 

What is it about the G1000 that pulls the frame down into the teens? I understand it may be a virtual display and all, but my video card is now slouch in that department. Not only am I a flight simulator pilot but also a heavy gamer, where my hardware is put through (what apears to be) much, much higher stresses at the display level.

 

Here's a final breakdown of the issue...

 

Frame rate can be locked at 60FPS, but when the G1000 is turned on it will plummet to 14FPS and begin bobbing between that and about 24FPS unpredictably.

 

Frame rate can be locked at 30FPS, same issue.

 

If the engine is started and the G1000 is switched off, the frame rate will to return to a consistant 30 or 60FPS, whichever it is locked at.

 

I have a few other aircraft featuring the G1000, including Flight1's CT182T. Issues are the same as above.

AMD Phenom II 955 OCd to 3.6GHz

Corsair Dominator 4GB DDR3 @ 1.5GHz

WD Black HDD @ 7200 RPM

EVGA GTX560ti 1GB

I think you'll have a better chance at getting this answered in the FSX forum since your issue revolves around the G1000 and not the aircraft so I'm going to move this to the FSX forum.

A couple of points:

 

1. You don't have a high-end PC. You're absolutely correct that FSX is CPU intensive. An AMD Phenom isn't going to get you there. Most people would probably consider the i7 Sandy/Ivy Bridge or Haswell to be high-end for FSX. The sooner you can move to Intel, the better.

 

2. Whether or not you choose to move to Intel, you should consult one of the comprehensive setup guides available on the internet. Word Not Allowed's FSX/P3D hardware and setup guide is terrific. Avsim has it's own "official" guide as well. NickN, a longtime contributor to the community, is in the process of drafting a new guide (he calls it the "Bible"), providing yet another approach. Pick ONE, and follow it to the letter, starting with a clean FSX install--and, preferrably, a clean OS as well. The key here is to pick just one guide, since they offer different (i.e., sometimes incompatible) approaches to increasing performance.

 

Edit: If you can upgrade your GPU to the GTX680 or 780, that will help as well. Money, money, money...

Keep in mind that CUDA was still on the drawing board when FSX was made.

 

 

I've got a similar system to yours* and GDI programmed displays (e.g. G1000) tend to drag my framerate down, so I simply avoid planes that are equipped with them.

Glass cockpits tend to put an extra heavy burden on the CPU.  FSX has always had a reputation for performing much better on Intel CPU's and Nvidia graphics cards.  AMD's processors have lagged behind Intel's in terms of performance since the advent of the Intel Core2 series of CPU's.

 

What you might do to try to improve performance is to turn down or turn off AI traffic, especially road traffic, and set your graphics sliders one or two notches below maximum.
