    Re: OpenGL 3 Updates

    The reall memory size and other requirements put on the texture memory might change in unexpected (for external observer) ways between formats or texture sizes depending on what the hw requires. Even...

    Re: OpenGL 3 Updates

    Yes drivers lying and optimizing to gain few fps in benchmarks is problem which the API can not directly solve. The only thing the API can do is provide strong mechanism for specifying the program...

    Re: OpenGL 3 Updates

    The GL_VERSION string has first part before the space well specified. Actually some people got incorrectly even Windows version check which returns structure with major and minor fields. This is why...

    Re: OpenGL 3 Updates

    The problem with the strings containing multicomponent information is that they increase chance that people will process them wrong (especially if they contain date). For example OGL version check in...

    Re: OpenGL 3 Updates

    Why would they need to do something like that if the discard is not worse that the alpha test? Imho it is more likely that they will modify your shader to add the discard to emulate the alpha test on...
