Sudden Framerate drops on overpowered PC

[Blake0812]

The fact that you had the problem before and fixed it proves that it has something to do with your computer, either a background program/service or settings in general. As Jens said those errors at the log are "harmless" and do not make the game lag. The issue is not with the game itself but rather with something which is interfering with it.

Well I hate to do this but I'm gonna reinstall Gamebooster and see if that makes a difference. Probably gonna isolate which program is running that's causing these drops.
