Mr. Marziaz (sp?)... help me ...

Recommended Posts

I have spent a well documented $2,700 for a machine that somewhat reliably attains 4.7GH and always attains 4.6GHz.

 

I have followed all requirements (minimalistic) as have been presented.

 

But still ... when I approach KFJK on the Parkway visual approach for 13L ... my fps drops to 14 ... ish ... and the presentation is jerky.  I don't care about fps ... I just it to be smooth.

 

Other than purchasing a Cray computer ... I'm at a loss ...

 

I do not use any add on scenery except for KATL and KFLL ... and Orbix Global.

Minimalistic as in all FSX sliders to the left?

No AITraffic?

 

What kind of REX clouds?

Dont use the HD textures if you have performance problems.

 

Make sure your anti virus software is not running with FSX.

 

Where is FSX installed?

On its own HDD or SSD or is it sharing space with something else?

 

What memory (RAM) do you have (including latency numbers please)?

Slow latency causes stutters.

 

Two monitors...are you opening up two FSX windows?

Cause in that case frame rate drops by about 50%!

 

EDIT: And I guess with #####...you meant...Why This Framerate...correct ;-) ?

There must be something wrong with your setup, i have a medium spec setup with ORBX Global and payware scenery at most airports i fly in the UK and Europe airspace, my sliders are nearly at max, and the 777 handles perfectly!!

 

I think before you blame PMDG for performance issues you should really check out if there isnt background programs eating up your memory and cpu.

Hi gents,

 

Yes indeed, i run a Q9550 at 2.83GHz (not overclocked at all), 6GB RAM and a GeForce 480GTX at 1.5 GB VRAM.   I get very good frame rates 95% of the time.   I think there is something amiss with the setup there mate.   What other software are you running like anti-virus software and the likes?

 

Kind regards

Where is FSX Installed?  This was a custom rig built for FSX to NickN's specifications:

 

FSX is installed to D:MSFSX ... a 120GB Sansung 840 SSD

 

Antivirus software is set up to exclude the entire D drive.

 

Before we get into any hardware considerations ... read this ... it documents a month long immersion into my entire machine ... including delidding, lapping ... and stress testing.  At 4.6GHz all temps, using all tools available, never leave the 60C range ... there is no throttling going on here.

 

Memory ... Latency ... quantity ... recommended by NickN ... I even returned my Corsair Dominator Platinum for these ... (DDR3 2400 (PCS 19200 ... 9-11-11-31 CAS 9 ... not overclocked) ... smoke tested each and every one of them, individually, using MemTest 5.0 ... before the OS was even installed.  The only advice I didn't take was to use 4 sticks (instead of 2) of 4GB for other applications ... like Photoshop ... installed on C: (a 250GB Samsung 840 series).  But, I never planned to OC the memory anyway.  And yes, I'm stable running the stock MHz ... (Timings ... DRAM Frequency of 1200.0MHz ... which is 2400 ... remember ... there are two cycles to a sine wave).

 

NorthBridge is running at 4200.0 MHz.

 

And, finally, and this is most important ... I'm not blaming PMDG for anything ... I simply reached out to Ryan in the hopes that he'd offer to tunnel into my rig and see what's wrong ... I'd even offer to pay a nice steak dinner at Outback ...

 

Yes, there is something wrong with the setup ... thanks for pointing that out :lol:  ... which ... by the way ... is why I'm here!  But for the life of me ... I can't figure out what it might be.  Now ... that the particulars are out of the way (and did you enjoy the read about how to delid and lap an i7) does anyone have any viable suggestions?

 

Luv ya guys ... appreciate the great work!

All I can say is you fell into the same trap as everyone else - spend as much as possible on top-end equipment, completely ignoring what a POS FSX is as a piece of software, and then wondering why it doesn't work very well.

 

My current computer is 3 years old, cost 1/6th the cost of your new rig, and I get a cool 40 FPS minimum with the 777.

 

I'm betting you bought Intel/nVidia, right? AMD user here.

 

Don't take the tone of my post the wrong way - I'm sure your rig is great, but it is common theme among Intel usres around here that if they buy the fastest systems, overclock it to the point of breaking it, and "do all the tweaks", it will run FSX flat-out.

 

I come along, give a dose of reality (that gets ignored every single time) then I watch it happen again a month later.

 

I'm outta here +TSRA inbound.

 

Best regards,

Robin.

It's not the AI traffic, Charles  ...

 

Can you measure your temps (CPU/GPU)? Freeware tools are available. Might be an overheat issue.

 

FSX is fully patched (SP1+SP2)?

 

HIGHMEMFIX=1 in fsx.cfg?

 

Do you use an AffinityMask entry for the fsx.cfg? Does the entry suit your number of cores? Hyperthreading on/off is reflected in the entry? Does your CPU utilization go up 100% (HT off) or up to some 60% (HT on), which would be good? Just for testing, disable this entry and try again.

Robin ... thanks ... for nothing ... (no offense intended). 

 

Your comments provided no value except to justify to the forum how great you are ... I'm here to tell you ... if you are flying a T7 with a rig that cost (1/6th of mine ... note the dirth of  technical specifications) and you are getting 40 fps ... then you are a God ... and I bow and worship at the feat of your obviously fantastic capabilities of tweaking HW and SW and FSX.  I will purchase your machine for $450 ... including shipping ... just to find out ... and report back ... if you are what you say you are.  Just give me your PayPal address ... and the deal is done ... but if I find out you are not what you are saying you are ... you owe me double the principle and triple the shipping cost ... deal?

 

I have erected a shrine to Robin ... just over there in the corner ... it is encrusted in gold ... and it cost 1/6th the cost of ... well ... nothing.

 

I buy computers every four to five years to last for the next to five years.  It just happened to be that at the time I decided to build my next rig ... FSX was a hobby.  You stick your neck out and proclaim to the world that AMD is now the preferred implementation platform of FSX.  Really?  There are facts out there that contradict your proffering.

 

Oliver ... temps are absolutely irrelevant ... with all cores ... using Prime95 ... for hours ... temps only reach the low 70s ... all FSX processing keeps the temps in the high 40s to low 50s.

 

Acceleration installed ... answers that question.

 

HIGHMEM ... yes ... of course ... first thing.

 

Affinity Mask ... not yet ... did some research ... didn't think it was worth the effort ... will talk to Nick about that.

 

HT is off ... as per NickN's bible.

 

I'm sitting at KIAD at Gate 100 with the T7 and CPU usage is at 36% ... Core 1 is at 100% all the time ... and 2, 3 and 4 are around 20 to 30.

 

Just can't figure it out ... I'm sure it is something simple I missed ... keep asking questions.

Charles,

 

What if you run some non-FSX benchmarks to see if your machine performs as expected outside of FSX? I don't know how but could you run, say, the Passmark test and see if your results look right? That way you could isolate the problem to be either in or out of FSX. If your machine smokes the benches then you'd know that it's something with FSX, but if your non-FSX performance isn't where it should be, then maybe it's a bad bios setting or even, sadly, some bad hardware.

 

Hope this helps.

Try creating a fsx.cfg file using http://www.venetubo.com/fsx.html.

What is your AffinityMask set to in fsx.cg?

Reason I say that is core 1 should not be 100%, it could either be FSX (which shouldn't use core 1 much) or something running in the background of windows.  When I run fsx, it always uses cores 2-4

I'm going to suggest something you will probably regard as silly (or perhaps it was one of your first steps).

 

Back up your fsx.cfg, delete or rename it and let FSX create a new one. Put in the himem tweak and nothing else, adjust your sliders and note any results.

 

Sometimes things just get too freaky tweaky. Only takes a second and removes a variable.

 

Good luck. I'll be watching because if you find something that works, it may well work for all of us.

Hi,

 

No need to go that far. I'd send my rig but I need it for work.

 

 

 

I'm sitting at KIAD at Gate 100 with the T7 and CPU usage is at 36% ... Core 1 is at 100% all the time ... and 2, 3 and 4 are around 20 to 30.

 

Do you have add-on scenery here? Which runway (or gate) are you sat at?

 

As for my FSX settings, I disabled completely:

 

* AI

* AutoGen (who needs that at FL390?)

* Bloom

* Dynamic weather/weather rate of change (yes, this actually hits perf more than people think, and it is often enabled bvy 3rd party weather programs - it has also been found to be the source of the super high TAT bug)

 

I have no add-on scenery except for UK2000 range of airports, and FlyTampa Kai Tak and St. Maarten.

 

I run FSX at 1600x1200, AA/AS are set in the driver, FSX AA option is disabled, and AS is set to Anisotropic.

 

Frame rate is set to UNLIMITED (very important).

 

I run FSX in a window, only because task switching eventually causes FSX to crash.

 

I have no problems with UIAutomationCore.DLL, though I usually disable it by preventing system access to the DLLs themselves, and restarting the computer to clear it from memory. It causes a couple of programs to stop working but I don't need them when simming (most notably CCC crashes if a tooltip appears - work-around is don't hover long enough for them to display).

 

My system specs:

 

* AMD Phenom II X4 970 BE (3.5 GHz stock) AM3+

* 8 Gb DDR3 memory

* ASUS A4M89GTD/Pro (890GTX chipset)

* 1 Gb AMD 6790

* Win Server 2008 R2 SP1

 

...not even top of the line when I built it, though I spared no expense on the motherboard or memory.

 

 


Back up your fsx.cfg, delete or rename it and let FSX create a new one. Put in the himem tweak and nothing else, adjust your sliders and note any results.

 

Sometimes things just get too freaky tweaky. Only takes a second and removes a variable.

 

+1

 

I don't run any of these snake-oil tweaks - they don't work. The only reason HIGHMEMFIX=1 works is because that materially changes how FSX processes graphics. The rest are just nonsense.

 

Best regards,

Robin.

Charles,

 

This is what I did when my high end machine got out of whack - Go to the setup guide TABS created and set your machine up using 4XS and follow all of TABS recommendations for a low end machine.

 

If you have the B737, RR did a very good review on setting up the B737 in the manual.  I followed it to the letter. 

 

TABS did a rework of on the  machine of one of the members.  Find that thread and compare that setup to yours. 

 

Check VAS.  I am using VMMAP as recommended by one of the forum members. 

 

I have a high end machine and it got out of whack.  I went back to basics and all is now good.  One thing is I do not overclock.  Hope that helps for a start.

You have a rig almost as mine with the same processor OC at similar speed. In fact, you have a better GPU.

I have not seen that poor performance on KJFK with my FSX setup.

But to be sure, I will try that same landing approach this evening.

I you don't see a post back tomorrow is because I could not duplicate the problem.

Robin ... our discourse began poorly ... the most valuable action on these boards that all of us must adhere to is this ... turn the other cheek ... be kind ... have a righteous heart ... and most importantly ... forgive ... and move on. 

 

It was nice to meet you ... and I mean that sincerely.

As funny as this may sound, you might want to run the FSDT JFKv2. On my rig which is a 2700K (not clocked yet), 8GB RAM 2133mhz, and a GTX670FTW, I get a LOT better performance out of the FSDT JFK vs. the default version which isn't really optimized to todays standards.

 

Also, I am setup per NIcks instructions, however as he notes somewhere in those instructions, sometimes when running a plane like the NGX with complex addon airports, you may need to unlock the frames and run unlimited.

When I run the T7 or NGX I go from locked at 30 to unlimited and set the Vsync in Inspector to Force On, not 1/2. With a lot of testing I have found that works best for me in these type of situations and is still smooth and stutter free. Although it might not work for you, its worth a shot.

 

Below is a quick grab into 13L in the T7 with FSDT JFK, MegaScenery NY, and UTX night lights. FPS remained in the 50's most of the time and was smooth as silk. Plus I was able to run 70% UT2 traffic, but had the car and boat traffic turned off and that photoscenery doesn't include a bunch of autogen, so that might help as well.

Robin,

 

Re-enable your autogen and AI like the rest of us and tell us your FPS on final at KJFK.

 

Assuming FSX doesn't crash, it will be a very stuttery 15 if I'm lucky. If I max everything I get a paltry 5 FPS, depending on where I'm looking.

 

Best regards,

Robin.

I shall take it in the manner intended.

 

I suggest you try the suggestion about NO TWEAKS (except for the HIGHMEMFIX) and trying first without any AI or AutoGen, because no amount of tweaking can fix the memory leaks and problems associated with these. The perf hit you see depends on too many factors to list.

 

Be sure to run the latest FSUIPC at all times, as Pete Downson intercepts a certain class of crash and prevents it taking out the whole sim. No registration is required - just make sure FSUIPC is installed and running to benefit.

 

Above all - remember that FSX sucks as piece of software, and so if you try and max everything, you WILL have problems. I'd be interested to know how many suffered a CTD/crash/OOME during CTP. I know that during the crossing the number of pilots diminished quite a bit.

 

Best regards,

Robin.

so far I have gathered this

 

a $400 pc= a $5000 pc same frames for fsx

 

tweak it or dont tweak it

 

lock frames at 30 or go unlimted

 

disable autogen

 

 AI is fine...disable AI

 

this thread is a mish mash of information. I have found that basically your frames will steadily decrease after a fresh install. My last install got me 20fps at YBBN orbx on Orbx oz at max settings. Its now 12fps at sliders at max settings and no way to get back there again

Robin,

I'm sorry but I disagree with virtually everything you've said in this thread:

 

- AMD CPUs and GPUs are well known to perform worse in FSX than the Intel/Nvidia combination. I have personally had both and it's no contest. Their CPUs don't come anywhere close to the Intel stuff at the high end, especially in largely single-threaded applications like FSX. Even heavily overclocked AMD CPUs have trouble matching Intel's performance at stock speeds in benchmarks.

 

- A representative from AMD's driver team directly told me that they didn't care about FSX and wouldn't be fixing/optimizing anything related to it. I'd tried to get them to look into the performance issues in heavy weather/cloud situations and at the issue (which still exists even on the HD 7000 series cards) where offset diagonal lines end up running through 2D GDI+ gauges.

 

- AMD GPUs are involved with a high percentage of the bizarre graphics related tickets we get at support. Whatever AMD does differently than Nvidia in how they execute FSX's graphics results in a lot more of the skeleton VC and model stuff, blacked out scenery etc.

 

- The notion that HIGHMEMFIX=1 is the only tweak that does anything is just plain wrong. UsePools=0 and RejectThreshold are both well understood and result in higher framerates on modern hardware. When FSX was released GPUs had only 256 or 512MB of RAM on them and processed data streaming from the CPU at a rate that's orders of magnitude less than today's cards do. The vertex buffer pooling system was implemented by FSX's designers to stop the FSX graphics engine and the CPU from overloading the GPU driver with too much vertex data and crashing it. What UsePools=0 does is remove this throttle, allowing the CPU to send the maximum amount of vertex data to the GPU. When UsePools=1, RejectThreshold sets the size in bytes above which the pools system will send directly to the GPU. RejectThreshold = 0 is the same thing as UsePools = 0. This is 100% confirmed information that was given to PMDG by a former ACES programmer who was looking at the code when he replied to us - it is not speculation and he directly told us it would improve performance.

First,

 

thanks Ryan for the info. very valuable.

 

 

Second,

 

I have found that generally there are two approaches to setting up FSX, especially on highend rigs.

a) Set up everything to max, tweak to hell, and see if one needs to lower any settings

 

b) Set up everyting to minimum (or at least half the expected setting), only use conservative tweaks (highmemfix basically) and go up seeing what can the sim take until you are satisfied.

 

 

 

I found that second approach works better. Partly due to fact that you might end up with lower settings turning out high enough for you, partly due to fact you will not riddle fsx.cfg with every known tweak.

 

Some lower settings might even turn out better, for example you would rarely have full visibility in flight...

While 6+ miles is common, FSX interprets that usually as unlimited, and sets to whatever you happen to have in settings - meanwhile, really you would only by able to see maybe closest 60 miles around you...

I can totally back up this as i am testing DX10 and AMD HD7970 3GB GHZ Edition with and without Steves´s DX10 fixer and so far we have serious issues with ATI/AMD HD7000 series in FSX.
