no you dont understand, you made a cool soft for ESL, great, but it doesnt work for w7 pro, you are the dev, when you dev, you should take all env ! but im agree with you about m$ !
btw, you didnt answer to my question about dx11 feature, where and which i must disable to test, because it will be break my nuts if i must upgrade to w10 just for one game (or ask to ESL to find another system)
