Hello,

 

I recently finished a full sim reinstall, and It's all up and running now. I've tried copying my exact settings and tweaks so that everything would be as before the reinstall, however I've noticed one great difference. Now, after the reinstall, I've been getting enormous FPS drops as soon as my engines have been started up. As soon as they stabilize, My FPS drops from a stable 30-35 to 10-12. As soon as I cut the fuel flow to the engines, my fps jumps back tp 30-35. I never experienced this "drop" before, and I'm therefore wondering if there might be an effect setting or anything like that causing it, which I might have missed. I have this problem with all addon aircrafts that I've so far reinstalled, which are the PMDG 737, the 747, and the FSL320. The fps drop is significant and superannoying..

Im running the latest P3d version, V5.3. 

My specs are not the greatest, but i've never had an FPS issue before. 

Intel I5 8400

GTX1070 8GB

8gb RAM

nothing is overclocked.

Any ideas?

Check the affinity mask settings in Prepar3D.cfg.

If you tweaked them on your old install they may have reverted to default which may not be ideal.

Hi ray, thanks once again for a fast reply. I tried setting my affinity mask to 88, but the sim keeps reseting it to 63. I suppose it's because 88 maybee doesn't work with my processor. I've a 6 core I5 8400 , no HT, do you know how I can look it up, or do you perhaps know what the affinitymask should be set to?

Check this post -- (which includes a link to a AM calculator) -- 

 

Yeah I saw that one, I'm just to dumb to understand it 🙃. Have been reading through it for the last hour, nothing makes sense:-)

63 means all 6 cores are in use. With HT off that doesn’t give you any leeway.

88 is not useable.

I suggest using the following…

[JobScheduler]
AffinityMask=63
P3DCoreAffinityMask=63
MainThreadScheduler=0
RenderThreadScheduler=1
FrameWorkerThreadScheduler=2

Thanks, that's what my .cfg had before. Despite that being my Prepar3d.cfg I still have this fps drop problem. Do you have any other ideas?

Here's my Prepar3d.Cfg incase it helps troubleshooting.

Guys, if Wilhelm experiences a dramatic FPS drop after he starts the engines, it cannot be because there is something wrong with the default AM setting. Optimizing AM can help optimize the FPS a little bit if other applications are used alongside, but there is something other at play. (And if it was due to default AM, many others would see the same problem).

After you reinstalled your sim, you should not have "copied" your previous settings, but started with new ones. I recommend that you delete the cfg and configuration files and see if that helps.

I didn't copy any configuration file, I meant that I used my old graphic and lightning settings. But I will try regenerate my cfg and see if it helps, thanks. 

Wilhelm,

Turn EA off and change this entry.

Sure, but I had it running well with EA turned on before the reinstall, and I'd like to keep on using it. Do you mean I should stop using EA completely, because that might increase my framerate but it's not a fix to my problem.

It’s impossible to read through a cfg and make recommendations. I spotted two which I thought would help you.

EA eats fps with my more powerful 1080Ti but the higher resolution may be partially responsible.

I’m sorry but you’re going to have to go through it yourself unless you kept a copy of the previous one.

Without seeing your problem it’s hard to judge. Starting engines shouldn’t impact on fps. Does it also happen with default aircraft?

I had a similar issue a few years ago with P3d v4 that was related to using the audio system built on the motherboard.. Probably a long shot but do some troubleshooting like disabling the builtin sound card in the bios.

No, it seems as it’s only happening with add on aircrafts. I’ve tried seeing if I’ve have the same problem with the AC11, but couldn’t notice any drop. Maybe, since it’s not such an advanced aircraft the difference isn’t as noticeable, but it’s much more obvious with the large data-demanding add on aircrafts.
