I currently have an Intel i7-4790k overclocked to 4.7Ghz, 16GB DDR3 2400Mhz RAM, a Radeon R9 380 4gb DDR3 GPU, running Win 7, and completely up to date. More than powerful enough of a computer to run DCS, as my older, lower powered machine can do it.
From looking at the logs, it seems that it isn't finding textures, or can't render them or something, and it also appears that there is sound files or sound protocols that can't be initialized or found.
