Sure. In this code:
// --------------------------------- //
// USEASBMP bug
// --------------------------------- //
SETSCREEN 640,480,1
WHILE KEY(01)=FALSE
FOR loop=1 TO 100
SETPIXEL RND(640),RND(480),RGB(200,0,0)
NEXT
time1=GETTIMERALL()
USEASBMP
time=GETTIMERALL()-time1
PRINT "TIME TAKEN : "+time,0,460
SHOWSCREEN
WEND
I'm averaging around 1700ms for the USEASBMP command to work. Windowed makes no difference. Changing to 320x240 speeds it up to around 1680ms
