After my i5 3570k died on me last week, I decided to spend a few extra bucks and go for the i7 3770k.  Upon receiving it, I went ahead and installed it in to my system and overclocked to a stable 4.2 GHz.

 

Before, I was running the 3570k with a GTX 560 1GB video card, which seemed to be a good balance of CPU vs. GPU, with the GPU topping out at about 30% load.  I could consistently obtain a smooth 30FPS under just about any scenario.   Now with the i7 installed, my GPU load quickly jumps to 80-100%, and my frames jump from 30 down to single digits and fluctuate wildly.

 

After installing the chip, I disabled hyperthreading in the BIOS.   I started with a clean FSX.cfg and applied the tweaks that are found in the tweaking guide here at avsim.  The current tweaks of note are: bufferpools=0, FFTF=.15, Texture_bandwidth_multiplier=80, affinitymask=14, Highmemfix=1.  I went so far as to apply the venetubo tweaking tool .cfg and tried it.  Similar results across the board.

 

I also use the NVidia Inspector and use the common settings found here and elsewhere.  I have the GPU controlling the Antialiasing and Anisotropic filtering.

 

Seems to me that the CPU is sending more to the GPU than the GPU can handle.  This leads me to believe that I may have to set to usepools=1.  The only problem is that the more I read about using that in the .cfg file, the more confused I become.

 

Can someone help a brother out?  A good starting point would be much appreciated.

 

Thanks,

 

Matt

 

 

Why not just try the usepool tweak? You can always remove it if it doesn't work for you.

Take out the overclock. SpeedStep will run FSX just fine at 3.9 GHZ.

I don't know what's up.  Runs great in DX10 mode but DX9 is a pretty terrible experience.

The Master Chief is right.

 

Always listen to the Master Chief.

 

 

Also, DX10 itself is smoother than DX9, has not to do with your system (in this case).

Change Anisotropic filtering to "Application-Controlled" in the Nvidia Inspector settings and in FSX set filtering mode to "Anisotropic" and make sure antiailasing is unchecked.

Do you have your old fsx.cfg still?  If all you changed is the cpu, you could try putting that back in and just making sure it has the right affinity mask just to see what results you get.

Delete the FSX cfg, so FSX builds a new one.

 

Do NOT apply any tweaks at all.

 

Test without any overclock at all.

 

What do you see?

 

If all okay, overclock to your 4.2.

 

What do you see? What are the temps? Is the CPU throttling back due to high temps?

 

Are you getting artefacts in FSX with BP=0?If so reduce FSX settings like Autogen accordingly.

Well Matt I wouldn't go to the old usepools=1

 

Since you want to have less data sent to the GPU just simply downsize Texture_bandwidth_multiplier=80 to 40

Remove the terrain fiber FFTF=.15 so it's going to default 33 or you could even make it larger ;-)

 

Remove also the bufferpools=0 a far better tweak is see below

 

RejectThreshold=126976, //98304, 126976, 262144, 524288  (play with the different values)

(This is actually the only tweak I use in combination with AM and Highmemfix and TBM and TML the rest is just waist of time ;-))

 

Thanks for your advice guys.  I'll have to take chief's advice and remove the overclock, build new .cfg and see what happens.  I shall report back this evening once I give it a shot.

Did you stress test your overclock?  Did you apply additional voltage?  How do you know the old CPU died?  That practically never happens.  In my 10+ years of PC repair, having repaired literally tens of thousands of PCs I've seen all of 2 CPU failures.  Did you physically damage it or something?  

 

 

Thanks for your advice guys.

 

 

Matt,

 

Good decision my friend. That should resolve your bottleneck issue.

 

I'd also like to add a little something else if I may. Don't get caught up in all this overclocking and chasing frame rates. If you can achieve smooth flight running the aircraft and scenery that you wish, then just stick with that.  I run a first generation i7 computer with every high end aircraft and most of the high end scenery and the only time i struggle a little bit is when I'm streaming HD video and VATSIM audio of my flights.  In fact, shared cockpit in the Maddog is seamless, and hopefully it will be with shared pit for the Dash 8/4 and PMDG aircraft when they're updated for that.

 

I just prefer flying to tweaking, but I will admit there was a time I chased the frame rate thing.

 

Oh, I will be upgrading to a new computer this year, just haven't settled in on which way to go yet.

 

I think you'll be fine.

Andre, so if I understand correctly the higher the number on: "Texture_bandwidth_multiplier=80 to 40", the more the GPU will take the load?

Correct but it's a combination of the CPU and GPU same holds for the rejected threshold or bufferpools...

But in general your load on the graphics bus will be higher...

Very well, thank you!
