Bonjour, j'ai résolu ce problème après beaucoup de travail, il te suffit d'aller dans options dans programm files et modifie ceci :
[Graphics settings]
Brightness = 1 ; 0-10
FullScreen = 1 ; 0 = off, 1 = on
FullScreenWidth = 800
FullScreenHeight = 600
FullScreenBPP = 16 ; 16 bit / 32 bit
FullScreenRefreshRate = 0 ;
FullScreenAALevel = 0 ; AntiAliasLevel
FullScreenAAQualityLevel = 0 ; AntiAliasQualityLevel
FullScreenVSync = 0 ; 0 = off, 1 = on
WindowWidth = 800
WindowHeight = 600
WindowX = -2147483648
WindowY = -2147483648
WindowAALevel = 0 ; AntiAliasLevel
WindowAAQualityLevel = 0 ; AntiAliasQualityLevel
Shadows = 0 ; 0 = none, 1 = shadow, 2 = self shadow
Effects detail = 1 ; 0 = low, 1 = high
Texture detail = 1 ; 0 = low, 1 = high
Texture filter = 2 ; 0 = Bilinear, 1 = Trilinear, 2 = Anisotropic
EnableTL = 0 ; 0 = off, 1 = on
EnableHAL = 1 ; 0 = off, 1 = on
ShadowBufferSize = 0
Hardware Mouse Cursor = 1 ; 0 = off, 1 = on
[Audio settings]
Music volume = 6 ; 0-10
Sound effect volume = 9 ; 0-10
Voice volume = 8 ; 0-10
Reverse channels = 0 ; 0 = off, 1 = on
Use Miles = 1 ; 0 = off, 1 = on
Miles provider = Miles Fast 2D Positionnal Audio
Voila ! C'est tout simple. Cela doit venir de TNL
