Sudden FPS drop?

Featured Replies

Hi everyone.
 
Today, all of a sudden without a warning, my FPS dropped from approximately 25-30 FPS in EGLL to 6-8 FPS.
I have no idea what's causing this problem. I installed FPS_Limiter 0.2 earlier today together with a couple of airport freewares. I also changed some settings in FSX and in the fsx.cfg I changed TextureMaxLoad from 6 to 30.
 
Next time I opened FSX the problem turned up. I immediately removed the addons and changed TextureMaxLoad back to 6.
I jumped to different airports and it was all the same.
 
It turned out that this wasn't the only problem.
I started the 'default' flight at Friday Harbor using the AirCreation Trike Ultralight, and some of the scenery were missing and looked weird.
 
I run FSX: Acceleration on Windows 7 64 bit.
 
A list of my addons:
 
AirbusX
iFly 737
Ground Services X
FSDreamTeam Zürich
REX Essential + Overdrive
Ground Environment X - Europe
Ultimate Terrain X - Europe
EZCA
UK2000 Gatwick
FSRecorder
A couple of freeware airports
 
I would be happy to upload images of the incorrect scenery, but it says: "Upload Skipped (Error503)", so that's not possible either.
I have no idea what to do now, so I really hope you could help me.

the fps drop i used to notice on my laptop, it was due to the gpu or the cpu touching max temp or high temps so they used to throttle down, but it could not be the issue in your system. you could recheck  the addons and the GPU settings. check temps maybe it solve it.

 

you can recreate the fsx.cfg

 

you should always post your system config.

Already tried to recreate the fsx.cfg :-/ I will post my system config tomorrow - it's getting late here :-)

I'm not much into computers, but this I what it says under "dxdiag".

Download HWMonitor and play. When FPS drop, minimize fsx and check maximum core temperature and tmpin0 temp (Gpu)

I'm pleasantly surprised to see the initial response to this focus in on hardware instead of a hundred posts of various tweaks!  I don't however think that is the problem here, especially given that that it's more likely a heat induced problem would cause errors, which arguably could cause the system to slow down just before the software errors.

 

Better Settings::

Since you've rebuilt your FSX.CFG, you'll want to add / add-back the tweaks from http://www.venetubo.com/fsx.html before you report back on temps.

 

I strongly advise against changing any values manually except TEXTURE_MAX_LOAD (1024, 2048, 4096) unless you're exceptionally well versed in how those other settings affect rendering and associated timings, unless you're really into tweaking and experimentation. With your CPU and Graphics card, you should have performance you're happy with by using the website noted above.

 

Back to Heat: Given the processor type and associated date of release, it may be time for a good internal cleaning anyway, if of course that hasn't been done already. Just a guess, but if you're computer was built within 6 months of the processor release date, then it may be that it needs a good cleaning. The lint / dust can cause heat to built both by clogging up vent and acting as an insulator.

 

I sincerely hope you'll be able to return to enjoying your simulator very quickly. By all means report back to let everyone know one way or the other.

 

Happy New Year.

Hi Mephic and DaveCT2003.

 

I tried to download the HWMonitor, but nothing seemed unusual there. I also tweaked the fsx.CFG again, but that didn't help either.

I decided to do a complete reinstall of everything and so far, without any addons installed yet, it's working normal. I will try to see if I can find the problem, if it's caused by addons.

 

Thanks for your help - and Happy New Year!

Yep the only thing is to install them one by one and perform thorough checking which one is causing troubles
