Thanks for the info Fatback.

 

I went to look at that utility @ coder bag and saw "The first thing that you should do is to go to a resource manager to check if you have parked cores." I had HT enabled (stupid asus default bios setting I always forget to change) and saw in the resource monitor that cpu1 & cpu3 (and corr. ht "cpus") were parked.

 

Disabling HT in the bios and going back to RM - I saw no cores labeled parked. So I reckon that is one way of disabling parking.

 

Question I have now... does disabling parking w/ HT enabled increase fps. And curious what gain by up-ing thread priority (I'm too scared to use realtime btw).

 

@ Devon... my understanding too... applications either benefited or "not" from HT. FSX appeared in the "not" category. IDK tho... maybe this unparking the cores and/or up-ing thread priority changes HT behaviour wrt FSX. Who knows?

 

Sounds like a job for one of super-testers (e.g. Word Not Allowed... Hasse... )

I have Win 7 64bit and tried all of these suggestions. I noticed 0 changes in my FPS, except that the '*******' tweaks, which I've tried in the past, again gave me choppy frame rates and poor texture loading.

I went back to the backup FSX.CFG I created with Word Not Allowed's guide and I was back in smooth frames and texture loading.

 

Even with unparking my 4 cores of my i7 and setting FSX to a high priority (not doing realtime for safety reasons), I didn't notice any increase in FPS.

At FSDT KLAX my usual frames of about 23 in the NGX were still the same.

 

There must be something else hardware related that attributes to the OP's increase in frames.

I think it says something, that similar threads pop up monthly or even more frequently. I think we can say there is a consensus that people desperately want more performance from FSX and are pretty much willing to try anything short of voodoo to get it. (probably would try voodoo if it was guaranteed to work!)

I done the unparked cores about 6 months ago, and did see a small performance improvement in FSX.

 

I am already doing all of the other tweaks (inc. Bojote tweaks which gives better results for me - and maybe other ATI users - than Word Not Allowed's guide did).

 

I've not tried the priority increase so will give it a pop!

I've tried voodoo, it doesn't work :(

The best things I have found are :-

 

- Being fortunate enough to have a decent rig in the first place.

- Stopping your AV software while simming, (I use Avast Free), especially if it's a resource hog.

- Stopping unnecessary processes before starting FSX (I use Razer Game Booster)

- Being sensible with your settings, and making sure they are comensurate with your rig.

+1 for Razer's Game Booster it's great.

disabling hyper threading has no effect on performance. It's a windows feature that allows for better multitasking. you're not multitasking with fsx. This stuff is so bloody system specific. I got significant, repeatable gains in fps in saved, repeatable test flights with setting the priority to real time COMBINED with unparking my cores as did a couple of other people in here. The differences aren't wishful thinking. it's the difference between 12 fps and 25 fps over ultra dense scenery like seattle (orbx). I have no idea why or how, but it just works for a certain setup. Strangely, I get the best performance with the Bojote auto tweaker, whereas some of you say it causes major issues. The Word Not Allowed's guide (many of the same tweaks) caused me noghting but issues and poor performance whereas some of you say it made things great. Who the f___ knows. This is a strange beast.....I just wanted to post WHAT WORKED FOR ME in a very clear way so that it MIGHT work for even just one person. That's all. I've tried a lot of stuff....some works some doesn't. That's fsx.

I've never had any instability or crashing priority in RealTime. However, with my current audio drivers, I get crackling and audio artifacts only in that mode. I don't get any sound issues in High priority. I usually don't bother setting the priority to HIgh because for the most part, my rig gets 30-60 fps everywhere in high settings. The endless flight sim dream is high fps and great performance in all flight conditions, sigh. 10 gig processor would do the trick! ; ) five years maybe? .

I've been having problems with my H100 cooler and have to RMA it so have my FSX rig set to defaults with no overclock. Thought I'd give this a try anway and with CPU priority set to high and the cores parked I'm locked on 30FPS almost anywhere I fly. I flew into KORD this afternoon and dropped down to low 20's high teens but that's with US Cities X Chicago and FSDT KORD and 50% UT2 traffic. Even then it was really smooth. Once I'm back up to 4.8Ghz it'll be even better. I don't know why (FSX tweaking is an art, not a science lol) but it works for me. I'm not sure if it's the parked cores or higher cpu priority but I'm rocking. Thanks to the OP for this one...

I read through this thread and saw the claims of improved performance and the cries of snake oil. But I figured what have I got to loose...

 

My starting point was with scenery density and medium and on a clear day with no AI in site and not a cloud in the sky I was lucky to get 17FPS with plenty of freezes and screen stutter.

 

I followed the advice provided by the OP and now under those same conditions I'm running in the 25 to 30 fps range and silky smooth (no stutters or freezes). Wind the scenery complexity up another notch, add some AI traffic back in, and toss in a t-storm with precip' for good measure and I am running 20 to 24fps and still smooth as glass. That same combo before this would have put me down in the 11 to 14 range at best.

 

Color me happy!

So Tom...

 

This is using hyperthreading?

 

Thx,

5. Went into Task Manager/processes/ and changed the affinity for fsx to 'Real time'.

 

Ok I'm on Win 7 X64, Im in the task manager now, clicked processes, and dont see where you change this. Could you describe what to look for here?

 

Thanks

Look for the fsx.exe... right click on it and then "set priority" on the menu... that brings up the next set of options... realtime etc.

 

Realtime can lockup the system... I'd recommend having everything backed up (good idea anyway of course).
