Ok I just tested in Riftbreaker as it has a demo. Happy to report FSR works perfectly fine without the new driver and the performance boost is nice!
**Note I had other crap running that probably effected performance. So my results are far from perfect. I just wanted to see if it worked**
Riftbreaker GPU benchmark
No FSR - Avg: 94.58
FSR Ultra Quallity - Avg: 121.77
FSR Quallity - Avg: 137.22
So working like a charm on my Radeon Fury. So allot less disappointed, still not happy but drivers going into legacy mode
