Hey folks. I have been experiencing this really annoying stutter/lag with FS9 for a while now; and I have no clue as to what is causing it, or how to solve it. Any ideas? (take a look at a video I found on youtube with the same problem). I have tried possibly everything at this point, including format and the issue still persists.

I have my fps locked at 55, when the stutters occur (in 1 to 2 second intervals) the fps are still solid at 55.Any suggestions?System specs:i7 975 3.33Ghz (boosted btwn 3.8-4.1Ghz) factory liquid cooled.16 GB 1333 RAMEvga 3GB GTX 580600 GB HDNo antivirus software running.All processed killed prior to gaming.

What Are Your Settings Within FS9? You Have A Nice System So Im Not Too Sure... What Are Your Ai Traffic Settings And How About Anti Aliasing? Also What OS

What is your CPU temp? I had the exact same issue as you on my I7, turned out the fan was faulty and the CPU was running hot.Regards

FS9 is maxed out (as it has always been). It is freshly installed since I formatted my pc. I ran a default test without AA or any additional graphic settings and It still did the stuterring. I tried changing GPU and using my older GTS 240 SLI and it still did it (prior to formatting).. I have Win 7. I have nothing installed yet. Default everything till I solve the issue.. Interesting thing is that this is the first time doing this. I have installed it multiple times in this PC and it used to run smooth. Ever since I upgrade my GPU to the 580, I have noticed this lag.

I Agree With Rob I Had A Faulty Fan On My Old I7 Computer And Had Stutters.... So That Could Be Your Problem But Im Not Entirely Sure... You Could Tweak your FS9 CFG

Take a look...

Mine was running at around 80 degrees. As suggested also post your cfg.Regards

A lot of stuff needs to be fixed in that cfg. I'm on my iPhone so can't edit it for you. Hopefully someone will come along and sort it for you.Regards

Yes, Like i mentioned, It is the default cfg. No tweaks yet. lol.. Even with a modified CFG I was still having the same problem.

I've experienced the exact same type of stutters, also with an i7 975 (see the multi-page thread I wrote several months ago). Unfortunately I never found a solution. So, certainly do post up if you found anything that helps. I've scaled graphics back from the PMDG-recommended settings through nVidia Inspector and set FPS to unlimited with an external limiter to 60. That's the best I've been able to do but will get stutters every few seconds like yours nonetheless.

Have you tested the CPU at stock speed?

Have you tested the CPU at stock speed?

Actually did that not too long ago. And the problem still persists. I think it's the nvidia drivers.. Prior to using the GTX 580 I used the GTS 240 with nvidia 186... drivers, and it ran flawlessly. Unfortunately there are no nvidia 186.XX drivers for the 580...

Well... After a bit of testing I have come to the conclusion that the problem are the nvidia 280+ drivers... Reverted to my GTS 240 with drivers 185.26 and the problem has been solved.. Sad thing is I can't use my GTX 580 with fs9 :(

Guys I have the same identical issue, costant fps a 30 fps (locked at 30), never go down this value, but I have this regular and costant lag on the groun and in the air.

 

I'm using 344.11 nVidia drivers, and have a fresh install of FS2004 with Maddog professional.

 

Any ideas or special setting to set into NI?
