Garnicht so simply, simply one simple Echtzeit-GameAPP-Window, that:
as many as possible FPS allows with F11 between Vollbild- and Window-mode switch can by maximize-Button into Vollbild-mode switch can a self-contained aktivierbare Zeichenfläche (Canvas) own (klick in that Window) the game into Pausemodus shifts, if Canvas inaktiv a brauchbare FPS-Messung with Speed-factor for RealTime supply
too must one first herausbekommen, that in that Memory bitmap (-1) draw not so meaningfully is How as if one whom Screen into hPic rendert, because mcopybmp slower is as one nProc nDrawhPic(... .
I access with this structure 1.500 FPS with 1.024x768, this gives Spielräume for even all The items which not mere with the display or the Window keep busy separate even with a possible game-code.
the tether is right simply, simply into gRenderer{ einklinken to startPaint gScreen.
