BETA Release OglaClient Beta 100416

[dumbo2007]

Right yeah....I forgot about the crash on Radeon cards.

By the way....there was some code available in MSDN on how to get the video card manufacturer using Windows Managed Instrumentation :

#define _WIN32_DCOM
#include <iostream>
using namespace std;
#include <comdef.h>
#include <Wbemidl.h>

# pragma comment(lib, "wbemuuid.lib")

int main(int argc, char **argv)
{
    int i;

    if(ShowVideoControllers() > 0){

}

Should compile with VC++
