Hello

@waldiamiga
Ok will test those demos

@Intuition
I have used the patch but perhaps it dont works with the demo WipeOut_2097_Demo
This demo works some time on os4/wazp3D but finally crash due to the memory hit bug

@kiero
I am using only glDrawArrays for all drawings (see below)
Now Wazp3D convert all primitives (like say a W3D_DrawTriFan) to triangles/points/lines list so now only the "newdraw" code is still present

/*==================================================================*/
void HARD3D_DrawPrimitive(void *hc,void *p,unsigned long Pnb,unsigned long primitive)
{
struct point3D *P=p;
struct HARD3D_context *HC=hc;
unsigned char UsePersp =(HC->state->PerspMode!=0);
struct TexCoord4f *V=(void*)HC->V;
unsigned int mode;
long int n;

HFUNC(HARD3D_DrawPrimitive);
OS_CurrentContext(hc);
VAR(P)
VAR(Pnb)

if(Pnb>MAXPRIM)
return;

if(UsePersp)
{
NLOOP(Pnb)
{

V[n].s=P[n].w*P[n].u ;
V[n].t=P[n].w*P[n].v ;
V[n].r=0.0;
V[n].q=P[n].w;
if(1.0 if(P[n].z<0.0) P[n].z=0.0;
}
glTexCoordPointer(4, GL_FLOAT, 4*4,HC->V);
}
else
{
NLOOP(Pnb)
{
if(1.0 if(P[n].z<0.0) P[n].z=0.0;
}
glTexCoordPointer(2, GL_FLOAT,PSIZE,(void *)&(P->u));
}

NLOOP(Pnb)
PrintP(&P[n]);

if(primitive==W3D_PRIMITIVE_POINTS) {primitive=GL_POINTS; goto newdraw;}
if(primitive==W3D_PRIMITIVE_LINESTRIP) {primitive=GL_LINE_STRIP; goto newdraw;}
if(primitive==W3D_PRIMITIVE_LINELOOP) {primitive=GL_LINE_LOOP; goto newdraw;}

if(primitive==W3D_PRIMITIVE_TRISTRIP) {primitive=GL_TRIANGLE_STRIP; goto newdraw;}

if(primitive==W3D_PRIMITIVE_TRIANGLES) {primitive=GL_TRIANGLES; goto newdraw;}
if(primitive==W3D_PRIMITIVE_POLYGON) {primitive=GL_POLYGON; goto newdraw;}


newdraw:
REM(newdraw)
VAR(primitive)

if(currentP!=P)
{
REM(P changed)
currentP=P;

glDrawArrays(primitive,0,Pnb);
