    Na da finds mal raus, du Drops.

    Bye, TGGC (Ein Jahr Helden)



  • Also bei mir funktioniert dass erste Projekt,
    wird wohl an deinem Rechner liegen

    Das zweite auch



  • Also bei mir klappt OpenGL nicht, wenn ich neue Windows NVidia Treiber benutze. Meine Grafikkarte ist etwas älter. Vielleicht probierts du mal verschiedene Treiber versionen aus.



  • Oder verschiedene Gehirn-Versionen? Mit Autocogito und so....

    und auch denken



  • Die Standard-DevCPP Templates sollten eigentlich überall funzen.

    Ich tippe auf eine schrottige OpenGL32.dll.

    Hast Du MS "Treiber" drauf?



  • ich bin mir ziemlich sicher dass ich nicht die standard windows treiber für meine riva tnt 2 hab, sondern irgendwelche aktuelleren



  • ein update auf die neuste version des graphikkartentreibers hat das problem beseitigt.
