- Well, I have come up with similar results using 704x480 HAM8 and PPshow30
- This was displayed in interlace (I only have a 1084 style monitor)
- I loaded the anim into View3.2 and it reported an average frame delta of
- 127K (quite high yes, but ~4FPS !!??) Geez, glad I kept my DCTV.
- I was hoping for better than this.
