Why GSdx9 not suppost MTGS??

[SSforME]

The zeroGS supposted the MTGS,but the GSdx9 not.
Why??
And how to make the GSdx9 suppost MTGS??
I am interesting in it.

Simply because Zerofrog added DC/MTGS features to PCSX2 and also wrote ZeroGS, while Gabest wrote gsdx9 and is the only one that would know it well enough to implement those features into it.

AFAIK gsdx9 is discontinued because gabest doesn't have the time to work on it anymore. So don't expect to see it in the future.

Exactly.

Actually MTGS and GSDX9 can actually do work.

However, the main problem seems to be incompability between these two stuffs. Actually if you're lucky, or patient, sometimes, games like Resident Evil 4 and SRW Alpha 3 will work with MTGS/DC and GSDX. Resident Evil 4 actually looks very identify to the PC version 1.1.

I found some code with MTGS in GSdx9 source.

#ifdef _OPENMP
// need real cpus, with HT it is only going to be slower now
omp_set_num_threads(omp_get_num_procs());
#endif

/*
// return;
// omp_set_num_threads(2);
//
{
int tmpsize = 1024*1024*2;
BYTE* tmp1 = new BYTE[tmpsize];
BYTE* tmp2 = new BYTE[tmpsize];

for(int i = 0; i < 1024*1024; i++)
((DWORD*)GetVM())[i] = rand()*0x12345678;

GIFRegTEX0 TEX0;
TEX0.TBP0 = 0;
TEX0.TBW = 16;
GIFRegTEXA TEXA;
TEXA.AEM = 0; // 1

__declspec(align(32)) static DWORD dst[1024*1024];

int nthreads[] = {1,2,4,8};
for(int j = 0; j < countof(nthreads); j++)
{
omp_set_num_threads(nthreads[j]);

clock_t start = clock();

for(int i = 0; i < 1000; i++)
{
unSwizzleTexture32(CRect(0,0,1024,1024), (BYTE*)dst, 1024*4, TEX0, TEXA);
// for(int k = 0; k < tmpsize; k++) tmp2[k] = tmp1[k];
}

clock_t diff = clock() - start;

CString str;
str.Format(_T("%d threads: %d ms"), nthreads[j], diff);
AfxMessageBox(str);
}

omp_set_num_threads(2);

delete [] tmp1;
delete [] tmp2;
}
*/
}

But the omp_set_num_threads() was not definition.

How to finish it???
