- : video card bandwidth ? interleave pixel write ? c2p ?

-
- Well, if you can save >30% by doing the above why not (Copy to video
- card and do rgb->yuv conversion)? You can go from 15fps to 20fps...
-
- : A factor could be 24bit->ham.
-
- I was talking about speeding up mpeg player on chunky GFX cards...
- On aga/ecs the cpu interleave time is waisted by the c2p code.
- So even so people say its 'free' on 040 +, its c2p is not free at
- all!. On something like MP is mean no free yuv conversion on
- game like doom it mean no free texture mapping.
