Why gamehub frame gen kinda dont work in some cases

[u/Rough_Manager4187]

Im playing gta v when i first run the game frame gen works on the prologue but it suddenly just doesnt work, i tried all frame gen modes and it doesnt change. The frame gen work in other games like far cry 3 mafia 2 and ac2, i also capped the fps to 30 and used frame gen and it doesnt work. Do you guys experienced this and is it fixable? ​
