Are you running a beta version of PUBG Mobile (like 1.0.2 or 1.0.3) by any chance? The latest version available for me to download on Google Play Store is 1.0.0 which does not enable 90 FPS gameplay on ROG 3.

[GhostRecon]

No..I am not in beta version. It's showing me 90 fps in smooth

Also, I noticed fps stability is not good at 90 fps( even without screen recording)

Did you download it from Google Play store?

[GhostRecon]

No . could be this because it's not from playstore? Do Rog 3 support 90 fps officially for pubg?
