Windows 10 in combination with oculus runtime 0.5 and vorpx 8.1 seems to work but it is not perfect. Thnx for the suggestion @BuckleBean! I will just wait for the 0.9 update then.
I just bought vorpX for my oculus rift but then I came to the conclusion only runtime 0.7 is supported for windows 10. Is there anyway around to make vorpX run on a windows 10 pc at this moment?
