Impact of planes size
Posted: Wed Jun 17, 2015 8:39 pm
Hi,
I'm currently rewriting my map scroll engine.
One of the alternatives is to use large planes to 3x3 viewport idea
If I use it, i'll need to use large plane size (64x64 or 128x128)
So here comes my question :
is there any direct impact on
- memory (tiles available on VRAM?)
- performance (slower to scroll ?)
?
apart the problem linked to DMA, I don't remember reading any line about diff between 32x32 and 128x128 plane size...
Did I miss a post ?
