weird FPS problem

[Bladefeather]

When I'm playing SL, I don't usually get too much lag.  However, any time I open another window, my FPS drops to around 5.  It stays this way even if I close the other window, and the only way to get it to quit lagging is to close out of SL and then log back in.  Anyone know what's causing this?

are you using updated drivers and up to date viewer?

This has been a bug in the past, but should be repaired for some time now.

It's expected for the viewer FPS to drop when the viewer is out of focus or minimized.
The FPS should return to normal once the viewer is back in focus though.
It sounds like you are suffering from BUG-37795 - evere performance issues in all Second Life viewers after installing KB3176938 (Windows Version 1607 Build 14393.105). Problem continues with KB3189866, KB3193494 & KB3194496

Make sure your Windows is fully up to date & if you have Nvidia graphics, update to the latest driver version, that should fix it.

I updated my drivers and now everything is running great.  Thanks for the help!

I have an NViDIA GTI660 TI card  and after installation of fs (32 bits and 65 bits) frames were dropping to 2.5.

It starts at 77 fps then after a while a few minutes  it dropped to 2.5 then it went up to 77 fps.

I noticed some time between them so I checked for logging.

And It works for me now open firestorm and goto the debug settings

ctrl-alt-shift-s
MemoryLogFrequency 0 (default 600)

Somehow its related to huge fps drop and now i can use firestorm again. 

I hope it will help you too!
