i have a amd fx 8120 overclock to 4.4ghz with a gtx 660 no ti n some cfg tweaks n when i do day flying with pmdg i get around 30 to 20 fps but when night flying it get around 10 to 14 fps can someone help or give me some tweaks i know the 8120 is not that great with fsx

I would assume so. At night you have night textures, add to that all the lights and beacons and what not that have to be on as well at airports.

If you're using UTX's night lighting option, disable it.  Doesn't look very good and is a huge hit on performance.   I'm using 5 y/o hardware at 3.72Ghz and don't have poor night flying performance (relative to day performance).  I tend to avoid the NGX when in big terminals, saving it for areas my machine can perform well in.  I have most all sliders hard right except traffic.

This. Also, there's an add-on called ExperienceX which provides night lighting with little to no cost of FPS. In my experience once disabling UTX, day and night flying has around the same performance.

 

If you use any ORBX products, they also have a free addon which provides good performance with night flying.

In my experience, Experience X does have a performance hit that's just as bad as UTX, if not worse.  This is of course in dense metropolitan areas near busy airports.  Also, there seems to be a very small radius in which lights are displayed, and the light density is way too low.  I've tried it even with the latest update and am very disappointed in this product.  I contacted the developer for support and they did try to help, but it just doesn't play nice with other add-ons in my experience.

Thanks i am going to try this to see if it helps

Thank u very much that did the trick it was UTX causing the problem i just need now to tweak it a little more but now i am flying smooth

Old thread but I was kind of shocked to get an OOM error. I NEVER get them but did for the first time in over a year while flying at 5000ft over southeastern Canada at night.

 

I don't do much night flying and am surprised to learn night flying is actually harder on ones system. I guess all those city and street lights do add up.
