Hi all,

I have being using FSX se for along time and over the years many tweaks have surfaced with lots of  different opinions on what works and what doesn't and so on 

So the question is, and yes it is VERY subjective what tweaks are really needed in FSX se. I use Steve's Direct x10 fix

-Infinity mask=

-highmemfix=

-buffer pools=

Any others I have missed?

Cheers

You mean Affinity Mask, right? That's only if your CPU has HT (Intel) or SMT (AMD) and you have no desire or way to disable it. That, FFTF (only if you want to used in-sim FPS lock) and that's all.

Highmemfix is only needed if you have the Boxed edition. FSX-SE does not need that tweak.

BP=0 never worked for me.

In which computer are you running FSX now?

Hi Rhys,

The best advice I found with FSX was to avoid all tweaks (apart from highmemfix if you have the boxed edition)! 

When I first got FSX many many years ago I overtweaked it to the point where I had to uninstall and reinstall it.

After reinstalling it I then rigidly followed the Avsim FSX Configuration Guide when setting it up again and basically I haven't looked back since!

Cheers,
Bill

Hi 

Thanks for the tips 

Yes, Affinity Mask, my i5 multi core does not have hyperthreading. I have got that tweak in my cfg file, sounds like I need to remove it.

I might delete my current cfg file (back up the current one) and start with a clean and fresh cfg file. and follow the Avsim Config guide 

 

Cheers

Yes, that might be your best choice. Now you know you don't need any Affinity Masks.

buffer pools helps with artifacts popping in and out for me 

Just follow the helpful FSX FAQ from this site.

Also, if it is performance you seek, everyone is going crazy over the frame generation program called Lossless Scaling. I can literally play FSX with 10fps perfectly fine now, amazing stuff.

After migrating to a much stronger computer with Windows 11, FSX is worse than before when I used a Windows 7 box.  I observed that there's no point up-ticking the scenery settings, using the same reasonably low settings is the only thing that works (for me).

As far as tweaking the configuration goes, here's what I'm trying with moderate success:

-highmemfix=

-buffer pools=

-frame rate unlocked

with FSX, it's always a "wait and see" what happens depending on the area I'm flying.

What happens if you dial up the settings? OOM errors?

Two that I would add would be the one that improves LOD render distance for textures, if your PC does not take a performance hit. It did make cities significantly prettier for the textures. unfortunately the render distance for the object is dependent on its quality. i.e. the only way to have beautiful cities is to have custom scenery. Custom scenery draw distance is much further than autogen. Unfortunately the autogen is limited to the in game setting menu with respect to density, but they will always pop up at the last second. 

I have not tried it yet, but there is a setting that significantly improves draw distance for simobjects, i.e. ai planes. This I think is an absolute must, otherwie planes spawn into view 0.5 NM out, which is last second.

The main issue is not how powerful the PC is, but the 4GB VAS limitation of FSX. Unfortunately you can have a state of the art PC with a powerful processor and graphics card and lots of RAM but if you are using FSX with resource heavy addons (aircraft, scenery or both) then you might quickly approach the 4GB VAS limit which is when problems develop.

Although there is nothing to be lost by experimenting with things like LOD and AI draw distance, you need to be aware that increasing the render distance for both will add to the resource usage and increase the risks of an OOM (out of memory) warning as you approach the 4GB limit. AI aircraft, in particular, carry a significant VAS hit. Of course if you are mainly flying using default aircraft and scenery then VAS issues should be less of a problem.

Where is this FSX configuration guide?  All I find are dead links.

Here is a working link to the Avsim Guide.
Here is a working link to Nick's Bible
That should keep you busy for years. 

Thanks.

But that is version 1.0.  There was a version 2.0 put out in 2017.  But I can't find it.

I used a bunch of cfg file tweaks for the boxed version of FSX, but none for the Steam Edition.  The Steam Edition has the fixes already in it, so cfg file modifications are not necessary.
