TL;DR not included
I’m happy to update you that we finally understood what causes FPS drops for some of you. We’ve been working hard at trying to recreate this on over 30 different computers with vastly different specs with no luck. However, we now discovered that there is a Microsoft bug for WPF apps with transparent windows (like Overwolf) which leads to FPS drops in games. The bug is for users playing on Windows 7 machines, on windowed mode, with a transparent WPF application working in the background (Overwolf or any other), and Windows 7 Aero mode off.
We’re looking into how we can solve this Microsoft bug ourselves, or at least dramatically reduce its impact. Until we implement a fix, a possible solution could be one of the following:
- Enable Windows Aero – this will have close to 0 effect on performance. You can read more on that here.
- Play on full screen.
See you in game!
