FSX low performance with new PC

[Mark Hurst]

Gunning for a 4.5 ghz machine with a I5 is wishful thinking

I stand corrected. Nice Job..........

[alferra]

Sorry to but in guys, but one quick request to the OP

 

raulfernando, can you post a screenshot of your nvidia inspector settings ? I am thinking the other guys are headed the right direction with the CPU but just wanted to see if there is anything out of wack with your GPU. The 960 is a powerful card.

It must be frustrating for people who know better and have learned the hard way to always have to advise people after the fact about the PC they should have bought.

 

Typical process:

 

Step 1: Watch youtube video of amazingingly realisic flight sim

Step 2: Feeling inspired, buy really expensive PC with as much Ram and cores as possible.

Step 3: Buy FSX

Step 4: Install FSX to default folder

Step 5: Install the most complex airports, airplanes, scenery and weather addons known to man.

Step 6: Go into settings, turn all sliders up to full.

Step 7: Start flight

Step 8: Program crashes

Step 9: Restart FSX

Step 10: Restart flight

Step 11: Program crashes

>Repeat steps 9 to 11 many many many times

Step 12: Pour a stiff drink

Step 13: Join an FSX forum

Step 14: Start a thread asking if your computer specs are good enough for what you're trying to do.

Step 15: Weep uncontrollably when you are told your machine is subpar.

Nice job E-Buzz, always nice to get advice from someone with the same hardware that knows what they are talking about.

The thread made me think of the bad old days of overclocking when it was more or a art than the simple process it is today. Oh the intoxicating smells of over heating CPUs and motherboards, Oh the adrenaline rush you got from knowing that at any minute something could go bang. Oh the complete look of glee on the persons face behind the counter at the local computer parts store as you walked in, wallet in hand needing a new something because you've just blown it up. Good times, good times.;)

this is what I got after reset all bios from reset.

I have used to modify values AI suite 3

These values are with FSX open and runing and internet

[il88pp]

That looks much better.

multiplier is 16-39 (16 to 39)

bus speed is 99.98 Mhz (practically 100Mhz)

 

Clock speed will vary, as required, between

16x100=1,6Ghz

and

39x100-3,9 GHz.

 

Your FSX experience should now be much improved.

If FSX was running when you took that CPU-Z shot, something is not right.

It should have been running in the 3700-3900 mhz range with FSX running.

Not the idle 800 mhz. You sure FSX was actually running, not paused, etc?

That shot shows what it should look like when idling.

Raul,

 

This information doesn't help because it shows your global settings, not your FSX settings. Once again, I would suggest you forget about Inspector for now. Your video card will run FSX on a 1080p monitor perfectly well with no fiddling at all, as will almost any 3D-capable video card you could have bought in the last five years. You do not need nvidia Inspector and most likely you have messed things up by fiddling with it.

 

I suggest you reset the nvidia FSX profile to standard, like this:

 

(1) Go to your regular nvidia control panel (right-click on the desktop and select it).

(2) Click the 'manage 3D settings' option.

(3) Click the 'program settings' tab.

(4) Select FSX in the drop-down list.

(5) Click the 'restore' button.

 

Now forget everything else and adjust your FSX settings until you get some kind of reasonable performance. I gave some suggestions in my first message, for me those are the ones to try first.

I splashed out on a super-duper PC for 1100 GB pounds (1700 US dollars) last year and now all my high-end games and sims run smooth as silk.

The moral?- a good computer will be like a Godfather to you and make all your troubles go away..:)

Thing is.. He has a good puter. It should run well if he can get it lined out.

Clocked up that chip can be stout. At real high clocks it might even beat my

i7 at single thread. Not sure without comparing CPU bench scores..

[raulfernando]

Yes MBKHOU I got these values after reset from BIOS setting AUTO

In the AI suite benchmarking said 4.1 MHZ

[il88pp]

Is your fsx performance improved now?

[E-Buzz]

Hi raulfernando,

As il88pp asks, how is FSX running for you now?

And as MBKHOU says, when you ran CPU-Z and took the pic, was FSX running or was it paused?

If FSX was running, I believe there is still something not right - the voltage is very low, as is the multiplier. It looks like the CPU may be idling or not responding to load from FSX.

It looks like you were able to successfully change the Bus speed back to 100, which is a step in the right direction.

If at this point FSX is running with better FPS, despite the CPU-Z info, we're done.

But if your still getting the same in your first post, we still have some work to do.

Mark Hurst - Any idea if this is a Speed Step problem? Have you seen this kind of behavior before? I can't comment because I disable it on my mother board.

 

raulfernando,

Please do this:

Describe, step-by-step:

1. What you did with AI suite (also please post which version you have and what the current settings are).

2. What you did with the BIOS - what keys you used and what selections were/you highlighted and chose.

3. Which airport, aircraft, weather settings, scenery settings, and if FSX was paused or not, were used when doing the CPU-Z thing.

4. What other, if any, programs were running concurrently during this time.

 

Again, if your happy with the current performance, we're done and congrats!

I'm only assuming your still not getting good FPS performance yet...

 

E-Buzz :pilot:

[MBKHOU]

Yes MBKHOU I got these values after reset from BIOS setting AUTO

In the AI suite benchmarking said 4.1 MHZ

 

That would tend to indicate it was clocking up under load..

But...

Your benchmarking does not match the CPU-Z info. Are you adjusting

things after resetting in the BIOS? The reason I say this is because CPU-Z

said your multiplier was 8x39. With this setting, your CPU should not have been

capable of doing 4.1 mhz. It should have topped out at 3.9 mhz. This tends to

indicate to me that you adjusted things again after resetting in the BIOS.

Don't do that at this point! It's just confusing things.

 

I also noticed the low voltage on that CPU-Z shot. Wasn't sure what to make of

that. My i7 runs at 1.04 volts which should be standard as I've never adjusted the

core voltage.

[il88pp]

What CPU-z (CPUID) shows is a snapshot of the running system.

It Shows the current clock, and the current voltage. (the current current, lol)

The Voltage changes up and down together with the frequency.

Notice in the following shot the CPU is ideling (1600Mhz), and the Voltage is 0.840.

When my machine runs full blast, the frequency is 4000Mhz and the Voltage is around 1.12 Volts.

 

CPUID also shows the range of the multiplier that is set possible for the Processor. Mine is 16-40. Ideling at minimum 16x100=1600Mhz (1.6 Gigahertz), and maximum speed is 40x100=4000Mhz (4.0 Ghz).

 

(By the way, Mark hurst, you may want to download a new version of CPUID. Your version is very old. At least, the one in the screenshot is. Current version is 1.71 (generic) or higher (for specific mainboard versions). (Unless that newer version does not work with your slightly older 2550k of course.)

 

 

Anyway, my freq 1600 gave a voltage of 0.84.

 

In the screenshot (post 32) he is showing a frequency at the time of the snapshot of 0800 Mhz, and a Voltage of 0.75

That does seem reasonable to me, perfectly fine actually.

It looks like the machine was ideling at the time of the snapshot. FSX paused (pause on task switch on perhaps.).

 

So the voltage is not the issue.

 

I don't think there is an issue at all really. But he needs to confirm if his FSX is running ok now.

 

I have no idea why his processor throttles all the way down to 8x100= 0800 Mhz when it has nothing to do.

Mine goes no lower then 1600 now. Its set between 16-40. But, I have a different generation i5 (3570k), his is newer, 4690k. Maybe that's what causes the difference. - Or I could make mine go as low as 800 too, but apart from a mildly higer mutiplier I changed nothing in BIOS. All speedstep stuff is on as far as I know. Also C states.

So my CPU should be throtteling down as much as the chip can do I think.

 

My cpuid showing voltage and frequency while ideling. il88pp.

[MBKHOU]

His drops to 800 mhz because that's the low end multiplier for that CPU.

I'm not sure if it can be adjusted or not. 800 mhz is also the lowest this i7 4790

will idle. I turned that off as it made the puter sluggish for everyday use. And FSX

did run a good bit better with that turned off. I can set mine so it still uses the speed

step turbo clock on demand, but the Intel low idle is off and the idle is much higher,

in the lower to mid 3000 mhz range.

FSX ran a good bit better this way, and the puter was much snappier for everyday

loading.

But now, I've turned all the speed stepping off, and am running a constant clock

speed for all four cores. The CPU benchmarks show a slight decrease with it constant

3800, rather than "auto" with peaks to 4000. But... FSX ran better with the constant

3800 clock.

 

Maybe the voltage derate is normal.. I never watched mine in "Intel idle" mode to see

if mine does that. With the constant 3800 on all cores that I'm using now, my voltage

is parked on 1.04 v and never changes that I've noticed.

[Mark Hurst]

By the way, Mark hurst, you may want to download a new version of CPUID

 

Why?

[il88pp]

Hi MBKHOU,

Ok, the 800 is normal then. I did not, (and do not) , reccomend that he change that at all.

I also think for now he should not overclock at all.

His CPU is blazing fast already. No need to overclock.

 

Raul, I think you should set AI suite to default setting.

 

Then focus on getting fsx running ok.

About my pc, thanks, we talked about this before, with loki also there I think. I have since disabled speedstep (called differently im my bios). Also something like the c3 to c6 states (not 100% sure if that's what it was, I'd know if I'd look in bios again)

It worked, the cpu ran at max all the time. But I did not really notice much improvement. And, it gave me the heebyjeeby's after a while. Was afraid over overheating while 'ideling' even.

So I undid everything, hard bios reset, and set my old values up again. simply upping the Multi, that's it. There really is not that much difference, because while running fsx the cpu is constantly at max freq anyway. And since I bought my first SSD a month ago response time is great and programs start almost immediately.

As my case is small, with very little ventilation, throttleing down when idle is something I can use. And FsSX is running smooth as silk. Not a stutter anywhaere.

Thanks for your advice in all this, I'm learning a lot. You Always explain things very clearly.

[il88pp]

Why?

 

I noticed the version you have (1.59) only shows the current values, and not the Multi range that is set. (15-46 you said).

We (you) can see it is running at 4.6, but not where the Multi is set.

I thought you may like to see that info displayed as well.

 

For example your screenshot from post 15 shows a Multi of x16.

Raul, I think you should set AI suite to default setting.

 

I wouldn't use it at all at this point. I'd reset the BIOS again to stock,

and not do a thing else with the CPU, except maybe run CPU-Z to verify

it's clocking right. Then fire up FSX and see how it runs.

 

............Then focus on getting fsx running ok.

 

Yep.

[Mark Hurst]

Multi range...I thought you may like to see that info displayed as well.

 

Fair enough, that might be useful. I only really use CPU-Z to check if I've lost my overclock after my PC starts. With the current version I know that if I don't see 1604 MHz, something's gone wrong.

[razbdaz]

Hey Guys, have you ever looked at this post. I personally believe he is the go to for FSX issues and PC viability. I found the OC post extremely helpful in setting up my system.

Don't want to ruffle anyone's feathers, just a suggestion when I see Core voltage fiddling and concerns over PC longevity ......
