Unexpected FPS drops (Sometimes)

Unexpected FPS drops (Sometimes) - Sunshine Reflecting in Sea and a White Swan Raising Water Particles with Wings

I've recently run into a very annoying problem in Assassin's Creed Black Flag. I am playing this game on my laptop which have the following specs:

Intel Core i7 4510U @ 3.1 GHz (At turbo boost)
8 GB RAM
NVidia 840M 2GB
Intel HD 4400 2GB
Windows 8.1 64bit

When I start this game, I either get 45+ FPS or for some reason I get around 25 FPS on the SAME SETTINGS. Clearly, over-heating is not the problem here because when I am able to run this at 45+ FPS the FPS doesn't drop less than 40 even after 4 hours of gameplay.

Things I've noticed when I get 45+ FPS: GPU maintains a temperature around 65, and the GPU fan runs at full speed.

Things I've noticed when I get 25 FPS: GPU maintains a temperature around 44, and the GPU fan does not run at all.

Things I've done:

  1. Updated my NVidia drivers
  2. Went to NVidia Control Panel and set default GPU to NVidia
  3. Went to Nvidia Control Panel and preferred Max power for this game

Can any of you guys please point out where the problem might be?



Best Answer

Background process might be factoring in. Check what else is running and close any unnecessary programs.

If you have any programs like evernote or dropbox, check if their syncing schedule is during the times you experience drops?
