Hi I found this accidently while testing my engine, don't know if this work for all ppl tho....

instead of CLS you can replace it with these inside your rendering loop

Code: Select all

#include "crt.bi"
'
'
'
SCREENLOCK
Memset SCREENPTR, 0, w * h * bpp '(1/2/4) depending on BPP
'
' rendering
'
SCREENUNLOCK

here some result of blitting 32x16 sprite to cover the whole screen (20x30=600times)

Average FPS is (sum of 10 sec FPS) / 10

640x480 16
- Fullscreen
Average FPS : 426 Frame - NORMAL CLS WITH 2 PAGE
Average FPS : 534 Frame - CUSTOM 2 PAGE [+108]
Average FPS : 544 Frame - CUSTOM [+118]

- Windowed
Average FPS : 325 Frame - NORMAL CLS WITH 2 PAGE
Average FPS : 436 Frame - CUSTOM 2 PAGE [+111]
Average FPS : 418 Frame - CUSTOM [+93]

You could also do Line (0, 0)-(w - 1, h - 1), 0, BF... not sure how that would stack up, but I'd guess it's close to using memset.

So, just use Locate 0,0...

Plus that'll give you the option if you even want to reset it or not....depending on speed or algo....with cls, it uses it automatically, which is a waste if you dont need it...
