I have used -march=native -mfpmath=sse and now movies do play well. |
| 29 |
I'm still not sure why I had this problem. |
| 30 |
I did use mmx and sse use flags, but did removed them. |
| 31 |
Is it possible that my gcc didn't created good efficient binary before I |
| 32 |
used recompiled world? |
| 33 |
I really don't think so. |
| 34 |
I didn't use -march=native, but did find what my gcc find as native |
