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:
- Updated my NVidia drivers
- Went to NVidia Control Panel and set default GPU to NVidia
- 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?
