I'd like to see how my system stacks up against newest CPUs in this pretty severe test.  It won't take long to set up if you have the basics installed.  

 

1.  Set every single variable in FSX to maximum:  that's all traffic of every type, clouds out to 110M, ground & aircraft shadows on, every possible setting to the absolute maximum possible in the customized settings dialogue in FSX.  Set UPPER_FRAMERATE_LIMIT=0 in fsx.cfg

 

2.  Install REX cumulous cloud set #24 at the 2048 density setting.

 

3.  Change LOD in fsx.cfg to 6.5 after you've maxed out all settings in FSX, then closedFSX so that 6.5 does not revert to 4.5.

 

4.  In nV Inspector:  vsync at 1/2 refresh rate, frame limiter at 30, AF 16x, AA_MODE_METHOD_SUPERVCAA_64X...., and 8x Supersampling.

 

5.  Start FSX & load up the NGX engines running at KSEA 34R at dawn, weather set at Major Thunderstorm.

 

What are you seeing for frame rate sitting on 34R?  Thanks in advance!

Hi Noel:

 

Yep, I have all of that ... once I get my system reassembled tomorrow and test it out at 4.5GHz I'll set this up and let you know.

 

Have you purchased FTX Global yet?

Have you purchased FTX Global yet?

 

I tried not too because I had vowed to buy no more addons for the dying platform, however when I verified the license would be good for P3D too I went for it.  Haven't installed it yet though...

 

Thanks for offering to try this acid test!  

I'm not sure I got all of your requirements correct ... but I'm sitting at between 21 and 22 fps.

 

I just finished my new build and am running 4.5GHz @ Vcore of 1.28 ... "stable" after AIDA64 FPU Test of 60 minutes.  Temps rose to 80C and stayed right about there.

 

Hope this helps.

Whoaa ... back up there champ ... all I had was FTX Global installed ... after installing PNW my frames went to 15 to 16 ... that bloody test had all 8 cores at almost 100% ... where in God's name did you come up with THAT one!

fter installing PNW my frames went to 15 to 16 ... that bloody test had all 8 cores at almost 100%

 

Did you make sure ALL of the parameters set were identical, including Inspector, etc?  What processor are you using that has 8 cores?

The only thing I'm not doing is using that frame limited of 30 ... I ran textures at 4096 and 2048 ... little or no change.

 

Am I low or high?

 

C. T.

VC or 2D cockpit? Makes a diff on fps.

Default AI-traffic on max or some add on AI-traffic att max?

As far as I know C. T. has a 4 Core 4770K processor. And probably with HT enabled since he says "8 cores", which would explain the very high temps with AIDIA64 FPU stress test. AIDIA64 FPU stress test isn't that good for stess testing and checking heat. (C.T. hasn't updated his "My PC" info).

VC ...

 

All traffic sliders to the max

 

As far as the temps go ... when testing at 4.5GHz ... ASUS shot the Vcore up to 1.37 or so (Adaptive voltage for now)  ... those temps were not generated by a Vcore of 1.28 ... that's the unloaded voltage.  At 4.4 at 1.36V my temps were in the low 70's using Prime95 for an hour.  This is down from 93C before the delidding ... I consider that a success.  I also noticed that my H100i coolant temp, which previously stayed at 32/33, now rises to 40 or so when under heavy load ... the heat is now getting past the thermal die and into the cold block of the H100i ... which is a good thing.

 

Yea ... 4 core with Hyper Threading enabled ... haven't gone through NickN's document yet ... waiting for Chapter 103.  But this makes me question the statement that FSX doesn't use those four virtual cores ... they were at 100% with all the others.  Maybe I'm doing something weird hum?

 

Question:  When installing the texture from Rex textures I didn't see an option to control the size ... I just installed the clouds you wanted me to ... then in the .cfg file I set the texture setting to 2048 ...then 4096 ... where it is now.

 

If you really want to work through this simply give me a call ... phone number is in the About Me section ... probably the easiest way to get through this?

I personally don't use offset or adaptive voltage since I have no controll on what VCORE the BIOS will end up with. I use manual mode to be on the safe side.

 

OCCT Linpack (64Bits + AVX) is the best stress test when it comes to temps.

Enabling HT won't give you any benefits with FSX, only higher temps. Disable HT and you'll lower your temps with about 10C while stress testing with OCCT. FSX will use physical cores, but not virtual cores.

Sorry this is misinformation , FSX has no way to tell if it is running Hyperthreaded or not. Hyperthreading is totally transparent to the OS and programs....

 

To clarify: back when there were chips like a P4 that were single core but had HT, they had issues with FSX stuttering so I believe when the game was installed it only treated such machines as a single core and couldn't take advantage the multithreading code they put into SP1 for FSX

Stats:

 

Multiplier:  44x

VCore set to manual (1.29V)

NB Frequency:  3900MHz

HT disabled (though I'm beginning to question this)

 

Passed ROG RealBench V1.1 (which failed at 1.28V)

 

I just completed OCCT 4.4.0, CPU: Linpack, 64-bits, AVX Capable Linpak selected and ran it for an hour:

 

Maximum Temps in CPUID Hardware Monitor

 

Core #0:  66C

Core #1:  69C

Core #2:  66C

Core #3:  67C

Package:  69C

 

Starting full AIDA64 now ... finishing up with an hour of Prime95 and saving the best for last ... Intel Burn Test V2.54.

 

If all of that passes at 4.4GHz then I have a base from which to explore 4.5+.

So how much perfomance gain would you estimate that I would gain when enabling HT? Just wanna know what to espect when exposing 4 more "cores" to FSX. Must be at least 30 - 40%?

(Even though you didn't direct that question at me ... ^_^) ... but when I did the test with it enabled I wasn't blown away with the results.  I'm going to run it again with HT disabled ... after this round of stability testing is completed ... and see if HT really does anything.  People can talk all they want ... but when the Task Manager says all 8 threads are churning along ... I tend to believe what I see.

 

I don't expect anything anymore ... this is now firmly grouped into the domain of an "intellectual endeavor".  I've blown through ALL financial budgetary restrictions, estimated amount of time spent on this machine, time away from work ... wife is mad a hell and about not ready to take it anymore ... and I'm just getting started!  I hope to hit 4.7 stable ... I've done everything at the hardware level that is humanly possible to facilitate a good overclock ... EXCEPT spending the money on a custom cooling loop ... even I draw the line somewhere.

 

Now I'm on a mission to find out what every setting in that damn UEFI does and how it affects the machine. 

 

Then I'm going to follow NickN as he develops his Haswell guide ... then ... in a couple of months ... when all of this is done ... I might actually take the NGX for a spin (obviously loosing sight of what this machine was for to begin with!).

PS:  I'm selling my Corsair Dominator Platinum 16GB (2 x 8GB) DDR3 2400 MHz 10-12-12-31 (CMD16GX3M2A2400C10) for a $50 discount ... head on over and build.

So easy to loose yourself in endless tweaking Sometimes you just have to resist the minutia and urge to tinker...get in the virtual cockpit and enjoy it.

 

 

@UlfB - HT really doesn't seem to impact FSX in a positive or negative way at all on modern hardware....but Windows itself can benefit from having HT on. If you use addons or have other stuff running in the background then why not leave it enabled so they can benefit from it?  You can force FSX to only run on certain "cores" if you will by using affinity masks in the config file but if I recall correctly Phil Taylor said it wasn't needed after SP2/acceleration( I could be wrong on this , couldn't locate the article)
