Welcome to DXGL!

I have CPU i7-4790K, 16GB DDR3-2400, GPU EVGA GF GTX 780 Ti Classified with 361.75WHQL and Win 10 x64.
I tried to run config DXGL v0.5.8, to add profile "3DMark03" and to change to "non-resizable window".
I tested to run 3DMark03... but fullscreen mode only!??

I want windowed mode because we get ABNORMAL performance in FS (fullscreen) mode - FS mode is slower than windowed mode.
