The project cars wins 10 benchmark is outdated already.
since they are testing is b4 15.7,
b4 15.7 the win8 Amd driver does not have cpu overhead optimization, but the win 10 beta has some optimization already. So obvious we see win10 is faster on project cars back then.
Now I hope to see win 10 vs win 8 CPU overhead bench base on the new 15.7. To see win 10 really make a huge diff or not. If u got powerful cpu, u might wanna down clock a bit to see the diff.

Tried pCars, Win10 advantage is still there and quite significant.

Btw other games is nothing like this, they either marginally slower or marginally faster.

I guess Fiji really 'overclocked' to maximum for its current 'stock speed'.
No wonder AMD locks down the voltage to hide it.
