Hi, I have an issue with a loading thread on windows (with NVIDIA), while rendering a progress bar on the screen.

All work fine but, if i load a map without thread, just the main thread, it take like 700ms, If I use a loading thread, to load the map, create the shaders etc... on my laptop (NVIDIA GTX 770M, 3 GB) it take 5-6 seconds more (Windows 8)!!

On linux with ATI, (macbookpro 2011), it take the same time with or without the loading thread (around 1.5 seconds).

So is windows so crap, or I need to change the thread priority? I use std::thread on windows and linux.

Thanks for any advise!
