I know that AMD FX are not the bightest cpu's out there, but results on our forums for AMD:
Quote:21 | 20 | 60 | 53 | 37 fx 8320 | 16gb | gtx760
Quote:19 19 85 49 39 fx 8350 | 32gb | r9 280x
Quote:17 20 158 56 50 FX 8320 | 8GB | R9 280X
VS i5 which easy go into 80+ in that scene, like:
Quote: 25 112 50 30 23 i5 2500K | 8GB | R9 270X
or everything posted here, look like a huge problem for AMD owners. |

As expected!
The core 3D dlls are written by nVidia, nothing that runs good on any AMD hardware

But it runs well on Phenom II's -

So either it jumps between cores, ore uses x87, which is emulated on AMD FX and slow as f*** (Btw, you shouldn't be using x87 instructions in XXI century) |

Probably the first one since Windows scheduler is pretty bad with multicore. Give Windows a high load on one thread and you will see it jump betwen cores like a mad giving worse performance because of it.
I would try to force it to one core and see if that improves performance.

Same, first thing I tried - bind it to one real core - nothing. Tried with/without fx scheduler patches, so it's not core/cache thrashing or r`tarded windows scheduler with task jumping between cores. When I'm at home, I'll check if cpu frequency doesn't drop to idle there (which would be strange...) |
