    Kishonti GFXBench 4.0 crash


      Kishonti just released a new version of their cross-platform OpenGL benchmark - https://kishonti.net/news_single.jsp?id=27817230


      On my Optimus rig it passes all tests in a row with GeForce GPU, but not with integrated GPU.


      Note: GFXBench is picky with ALT-TAB


      I'm not familiar with your GPA so i tried good old IDA (demo 6.8), offsets below are after "memory re-basing" and only for the mentioned driver version.

      Works fine with single tests
