Big fall in FPS in long flights

[expat]

Not a big tube flyer but frequently will fly a heavy freighter long haul overnight while asleep and land somewhere interesting the next a.m.

Have good fps steady at 31fps for most other shorter flights, but when I check the long overnight flights the next day the FPS is down to about 3-4 fps. Yikes. Changing views or re-entering the a/c while in the sim does not improve things. Saving the flight and exiting/re-entering the sim (P3Dv4.1) however gives me back the solid 30 FPS. Otherwise PD3 runs smoothly and anomaly free.

Have an i7 4770k Haswell 3.5ghz Quad Core with 8GB mem, GTX 780 with CPU and GFX factory overclocked.

Any others found this?

Is your PC configured to run certain processes over night.....such as virus scans....defragging, etc...?

Runs a scan only at 2am every Tuesday. No defragging with SSD's.

If it's not a hardware overheating problem, then you might want to look into these 8 GB of RAM which might be a little bit low ?

His video card is really on the low end of P3D 4 specs too.

Rig is liquid cooled and no other overheating symptoms. When I find it running a long flight at 3 fps, exiting and re-entering the sim immediately cures the issue - it then runs at 30 fps (fixed) just fine, so if it were overheated this probably wouldn't happen.

Card memory is only 3GB so that, as well as the computer memory probably could do with a boost.

Dumb question (have not followed hardware specs in a while) - what would be the choice card to upgrade to and has the configuration/compatibility of motherboard slots etc changed from what I currently have for a single GTX 780? Mobo is Asus Z87-K, Intel Z87 Chipset

Also, to move to 16GB computer memory, my current memory is 8GB Total (2x4GB) Corsair Vengeance LP, 1600MHz. Would I just go to two stick of 8GB of the same? Is it likely I could just pop out the old and insert the new hardware?

Thanks much for your guidance.

Memory (RAM) upgrade is quite easy, it is indeed a simple plug&play.
It depends how many memory slots you have too. Currently you have 2x4 GB. If your motherboard has two more available slots for memory, then you could simply add another 2x4GB of identical RAM, that would work right away.

Another important thing would be: what version of Windows do you have ?
If it's Windows 7, you might run into maximum RAM limitation, based on which edition (home / home premium etc...) you have...

Helpful Daube, thanks. Winows 7 Professional 64 bit here.

Ah, the professionnal edition is limited to 192 GB of RAM, from what I read. You should be alright
