Laptop GT540M struggling with Havok physics?
This is a long-running problem with my laptop. Certain games, specifically Assassin's Creed II, Red Faction Guerilla, Saints Row The Third, and Sonic Generations, all have huge framerate drops. Seemingly at random or because of specific circumstances (some explosions/ effects destroy the framerate, other times the same explosion will occur at 50-60 fps with no problem). In every game, the framerate will drop to 10-15 fps. Not 5 fps, not 25 fps, always 10-15. And the problem gets more frequent the longer the game is running. But I've checked the temperatures, HWMonitor and CoreTemp say CPU cores are normal, 60-70c under load, and GPU-Z says GPU is only about 60c under load. And then I noticed all of the games use Havok physics. Games that don't use Havok (or with Source games, a modified version that apparently has no trouble on this computer), such as Mass Effect 3,The Witcher, Borderlands, or otherwise demanding games like Serious Sam 3, have no such issue. The global setting is GT540M and I've set every game in the NVIDIA settings to use the NVIDIA device.
Consistent drops to 10-15 fps regardless of video settings, only in games using Havok physics, laptop is in performance mode, and temperatures are normal. But it's not like this is PhysX where you can choose what device takes care of it, Havok is part of the engine. How could I possibly fix an issue like this? Is it a memory issue? Where do I even start? Maybe it's a CPU problem?
i5 @ 2.4 ghz
I'm terrible at this.
