Witam! Mam taki problemik, laduje sobie texturke do pamieci nakladam ja na czworokat a gdy uruchomie moj program to widze jak mi sie on troszke przycina a przeciez ta texturka zajmuje okolo 1MB i mam tez malo zmiennych tak samo mam z kursem zamieszczonym na stronie http://nehe.gamedev.net/d...n.asp?lesson=10 tez mi sie on troszke przycina podaje moja konfiguracje sprzetowa:
-Athlon XP 1800+
-GE-Force 2 MX 400
-RAM 256/333Mhz
czy ktos mi moglby powiedziec czemu tak jest??

PS A i jeszcze jedno ten program jest pisany w C++ OpenGL

  1. albo skopales cos z kodem
  2. albo to wina Twojego systemu, odpal program na innym komputerze

(co do punktu 1. to nikt Ci nie sprawdzi bo kodu nie zamiesciles tu.....)
