Framerate issues latest GPU driver

[Abysspurnyan]

Today I updated from AMD Crimson drivers 2.4.1 to 2.5.1, after this update everything except for Warframe runs fine.
Warframe appears to stick to 65 fps in orbiter, relays and missions.
The odd outliers here are Navigation, Cetus and Fortuna, where it actually goes to 120 (the cap I set for Warframe).
In both Orb Vallis and the Plains framerate appears to be normal until everything finishes loading, then it just sticks to the same framerate as any other mission.
Especially the performance in the open world hubs are odd, since normally framerate here is lower in the game due to all the players around.
One thing I've noticed is how the game refuses to utilise more than 35% of the gpu

My PC Specs are:
- Intel i7 6700K
- Red Dragon Radeon RX 5700
- Corsair 16 GB DDR4 2133mhz
- Asrock Z170 fatal1ty gaming k6
