Not flicker but tucker^^

If the Code looks like this:

Graphics 800,600
bglsetswapinterval(0) '<--- return 0

while not keydown(KEY_ESCAPE)
If MilliSecs()-timer>1000
timer=MilliSecs()
fps_=fps
fps=0
endif
fps:+1

SetColor 255,255,255
DrawText fps_,0,0
flip
wend

...DrawText return about 47-50 fps, display is running@115Hz. What should i do to achieve more than just 50fps -_- ?

I believe that there is a query over the accuracy of the MilliSecs command. For accurate FPS readings you need to find some way of querying the system's high performance timer. Sadly I do not know how to do this on Linux.

:( . Will this prob ever be solved? Or did i sth. wrong by installing the graphic card drivers, etc?

bglsetswapinterval is not currently implemented in the linux beta

ah, ok. Then i will code @ 47hz till this will be corrected ^^. Thx
