OS: Windows 7 x64 (Service Pack 1)
Video Card: ASUS STRIX-GTX1080TI (GeForce driver 391.01)
Bandicam Version: 4.1.4.1413
Bandicam Mode: Game Recording Mode
I would believe I have observed this issue with almost every game (examples include PlayerUnknown's Battlegrounds, Star Trek Online, Space Hulk: Deathwing - Enhanced Edition, Tera, etc). Bandicam is running, however when you launch the game Bandicam never hooks the game, never draws the FPS counter, won't record, and won't take screenshots even though it's running and responsive when I interact with it. In the past restarting Bandicam has fixed it, however lately it doesn't always resolve the issue.
The only installed Anti-Virus/security software is Emsisoft Anti-Malware (EAM), and I have exclusions set up for Bandicam, Steam, and all of my games so that EAM won't open hooks to them or monitor them.
The issue has persisted through multiple driver updates, and different video cards. I would believe it started with the introduction of Bandicam 4.x, however I can't quite remember. I think it was sometime around December 2017 that I started noticing it, however I can't be entirely certain on the date since I allowed so much time to go past before reporting it.
