Hi river1009
Thank you for your asking. First of all, please avoid overlapping thread or message, which may disturb the mods and the users to solve the issue. 
1. Does the issue appear right after any system/apps' download or update?
2. Had ROG supported 90FPS before? If it supported before, which version?
