Hi, this is sort of a weird problem.
Bandicams versions released in 2020 seem to be unable to record Ghost Recon Wildlands (2017 game). I know it was possible before because I have recorded it before.
PROBLEM - When the record video hotkey is pressed, the FPS counter blinks once, and doesn't go red. No recorded video file is present when I exit the game too.
So long story short - after troubleshooting, the "newest" version of Bandicam that can record successfully is v220.127.116.117. Any version AFTER this exhibits that behaviour I mentioned above. From v18.104.22.1684 onwards (this is the "next newer one" I have to v22.214.171.1247), pressing the record hotkey in Ghost Recon Wildlands will give that behaviour. The FPS counter continues to work, by the way. Just that video can't be recorded.
So yes, current version v126.96.36.1999 also can't record Ghost Recon Wildlands.
