Post Does Prepar3d make a cfg file based on hardware?
on: April 29, 2012, 16:23

I ask this question because I recently did an upgrade of my mobo and cpu. I went from an I7 950 to an I7 3960x, from 12 Gigs of Tripple Channel ram to 16 gigs Quad Channel ram, and kept my GTX590... You should have seen the look on my face when I loaded up Prepar3d for the first time after installing my new hardware... OMG... it was terrible!!! I mean a studder every half second, completely unflyable! (with very modest graphic settings mind you)

And my old 950 was good, not great but very good... So I decided to go do community tweaks, I actually took the lazy way out and went for broke with http://www.venetubo.com/fsx.html which is an online tool, I figured things really couldn't get any worse for my $1000 processor. To my amazement the cfg that they returned was night and day better than what I had been using...

Back with my 950 I never tweaked, I left everything default from the get-go and had great success. So I am wondering does Prepar3d do an initial hardware configuration to the cfg file, or was it just complete dumb luck?

ava_ati, based on the specs you list I think you were at the high end of the hardware spectrum already. Did you find the tweak section In the Prepar3D learning center?

I would be interested to know what you put in your .cfg and any performance notes you want to share. I've experimented with quite a few cfg files and computers and usually end up with different results. The http://www.venetubo.com/fsx.html site is a great place to start but on my current machine at home I've made some additional changes.

I haven't gone through the settings yet, been a long week. This weekend I am going to go through and see what it changed, especially since it the changes introduced a "prepar3d has stopped working" error. I would assume it is the bufferpools = 0 tweak, but I cannot say for sure as there was no error in the event viewer.

I was pretty close to the top end, but I was no longer at the top... I thought for sure there was no way that performance would get worse with the I7 3960x but that sure is what it is looking like... My next step is going to be renaming the cfg file and letting prepar3d create a new one. Then taking those three, my first one with the 950, the one edited by the website, and a brand new one created on the 3960x and seeing if there are any differences.

P.S. Another motivating factor in my upgrade is that my old ASUS board never turned off correctly, I would always have to cut the power off at the power supply to actually turn the computer off... That is the second board from ASUS that has given me problems, I will never again buy one of their boards.

This what I got; using the tool, you have to rename it, because filename is a fsx.cfg name
FPS Limiter is working as well.
see herehttp://janvaane.org/virtualfsx/?p=2565

Tweaking & Tuning Results for (FSX SP2/Acceleration - ESP - Prepar3D)
Based on your Hardware configuration and the current settings present in the Prepar3D.CFG file you just sent, we have determined some the following recommendations may apply to you. You are using the NORMAL setting, we'll simply recommend (but not change) sliders that affect performance at the expense of visual quality. All other tweaks will be applied. See legend for reference so you know exactly what was changed.
message in green simply indicates you had that option already optimized
Text in blue refers to actual tweaks that were automatically applied to the file you uploaded.
a red color indicates important recomendations we are NOT applying to your configuration.
AffinityMask not present. Adding for optimal results with your hardware.
You don't have a BufferPools section!, adding optimized settings.
HIGHMEMFIX was added to your config!
ALLOW_SHADER_30=1 has been added to make FSX Shader 3 compatible
Aircraft shadows removed for performance. Use Conservative to prevent this change.
Adjusting TextureMaxLoad to 12 based on your hardware.
SWAP_WAIT_TIMEOUT has been added to your configuration to prevent blurries.
SmallPartRejectRadius have been added to your config for performance
Adding MAX_ASYNC_BATCHING_JOBS for improved autogen batching performance.
Adjusting SOUND_LOD for improved performance when using AI sounds.
Removing overlay tips to avoid graphics corruption.
We suggest to try setting FPS to unlimted inside FSX, and use an EXTERNAL FPS limiter. You'll experience a massive performance increase. Download the limiter here
*** ATTENTION PLEASE READ *** the above changes were applied to the Prepar3D.CFG file you uploaded! not the one FSX uses! so, if you want to apply this to your configuration make sure you download the tweaked Prepar3D.CFG file suggested by the tool. (check below)

Yea mine said about the same, but like I said it created a "prepar3d has stopped working error," about one hour into my flight, so that is a definite no-go for me.

I've never edited my Prepar3D config.. Heck, I never even knew that learning center tweak section existed. I just checked it out and it was like running into an old enemy. :)

I hardly ever get blurries, great frames considering how high I slide everything over. You really need to try hard to get blurries with this sim at high settings w/ good hardware. Scenery sliders all maxed out (except mesh resolution which stays at 5m for Orbx), Airliner traffic / ga traffic 10% w/ vehicle, boat, ferry traffic at 0% and forced 8X SSAA. I keep LOD at 4.5 though for long hauls. I don't trust 5.5 and 6.5 yet and just use it for screen shots in short bursts. I fear OMM errors and those two settings are playing with fire for long haul constant use. (in my opinion).

With `another' sim getting blurries was like a constant reoccuring nightmare. Spend 1/2 the day tweaking to get rid of them. A few days later they return out of no where just to annoy you.

<3 Prepar3D now that I've sat and figured out its qwirks with certain addons.. :)
